About GIF Color Palette
Sample dominant colors per frame or globally and export a palette table for CSS, design tools, or re-quantization passes.
Each frame is decoded into a composited RGBA buffer, then we bucket pixels by 4-bit colour channels to find the most frequent shades. The result is a quick, deterministic palette suitable for re-quantization, theming, or export.

About GIF Color Palette
GIF Color Palette is part of a collection of single-purpose image editing and conversion tools. Sample dominant colors per frame or globally and export a palette table for CSS, design tools, or re-quantization passes. Each tool is intentionally narrow — it does one thing well rather than offering many overlapping features — which makes the common path predictable and the result easy to verify before you download or copy it.
The processing pipeline is straightforward: your input is parsed by standard browser APIs, transformed according to the options you select, and serialised back into a downloadable result. Accepted input formats are GIF. The 50 MB per-file ceiling matches what a typical browser tab can handle without paging to disk.
Most people land on GIF Color Palette via a search at the moment they actually need the tool. That shapes the design: the page is a single screen with the input on one side, the controls in the middle, and the result on the other, so a first-time visitor can complete the job without reading documentation.
The execution model is straightforward: your file is bytes in the tab's memory, the engine reads those bytes, computes the result, and hands the result back to the browser. The transformation happens locally, which is why the tool keeps working when your network connection drops mid-job and why it produces the same result every run for the same input.
A practical note on limits: GIF Color Palette accepts inputs up to 50 MB per run, and the tool processes one input at a time to keep memory usage predictable. If you ever bump into the ceiling, the cause is the size of the input.
For multi-step jobs, GIF Color Palette sits next to GIF Analyzer, GIF Lossy Compressor, and GIF to CSS Animation. None of them depend on each other — you can use GIF Color Palette on its own — but together they cover the common variations of the task this page exists to handle.
GIF Color Palette is shaped around the recurring needs of two audiences: designers preparing marketing assets, who use it as a quick utility between bigger tools, and developers preparing UI screenshots, who use it as their primary way of getting the job done. Both groups get the same defaults and the same speed.
When the job finishes, GIF Color Palette hands you the result as `{name}-edited.gif`. Filenames are derived from your input where possible, so a quick batch of jobs leaves you with a tidy folder rather than a pile of generic "output (3)" files. Nothing is auto-saved on Favtoo's side because nothing was ever sent there.
Some notes on the design of GIF Color Palette. The page is intentionally narrow: one input, the controls relevant to the task, and one output. Adding unrelated features would make the common case slower for the majority of users, so the surface is held to what people actually use.
GIF Color Palette is one example of a broader pattern: utility software increasingly works as single-page, client-side experiences. Every page in the catalog is shaped that way, which keeps each tool fast to load and easy to recommend in a single link.
Pro tip: GIF Color Palette works just as well in a private/incognito window as in a normal one, which is occasionally useful when you want zero browser-history footprint of the job. Another tip: if the tool ever feels slow, it is almost always because the browser tab is competing for CPU with another tab — pausing or closing the heavy ones gives the engine room to work.
GIF Color Palette runs as a regular web page, so there is no install step or permission grant before the first run. The page can be audited by viewing the source or by watching the developer-tools Network tab while a job runs.
When something goes wrong, the cause is usually one of three things: a malformed input, a browser that is out of memory, or a corporate proxy that is interfering with the page's static assets. The first two are easy to diagnose; the third typically requires asking your IT team to allow standard browser APIs to load.
That is essentially everything GIF Color Palette does and how it does it. Open the tool above, drop in your input, and the work happens in the page. If you find yourself reaching for it often, bookmark the page — it loads quickly on subsequent visits, and your most-recent settings are remembered for the rest of the session.
How it works
- 1Land on the GIF Color Palette page. The tool is ready to use the moment the page renders.
- 2Select the GIF file you want to process — drag-and-drop and the file picker both work.
- 3Adjust the options to match what you need. Sensible defaults cover the most common case, so you can usually skip this step.
- 4Trigger processing. standard browser APIs reads your input, applies the transformation, and writes the result back into the page.
- 5Save the output (`{name}-edited.gif`) when it is ready.
- 6Re-run with different settings as often as you want. Each run produces a fresh output and the original file on disk is never modified.
Common use cases

FAQ
Global vs per-frame palette?
GIF often uses local palettes; pick global merge for brand swatches or per-frame for accuracy.
Can I copy hex codes?
Yes — the generator output lists swatches you can paste into Figma, CSS, or other editors.
Why fewer colors than expected?
Transparency and dithering can consume palette slots; some frames share fewer unique colors.
Does sorting matter?
Sorting by luminance or hue helps designers; it does not change the underlying GIF until you re-encode elsewhere.
Browser differences?
Color picking uses decoded RGB values; minor display differences can occur with wide-gamut monitors.
Privacy?
Yes — palette extraction is computed locally in your browser with no mandatory uploads or account creation.
Why is in-browser GIF processing slower than online editors?
Server-side editors run on dedicated CPUs with native code paths and parallel workers. Our GIF engine decodes every frame with gifuct-js and re-encodes with gifenc — both pure JavaScript libraries running single-threaded inside your browser tab, which is typically 2–5× slower than a backend pipeline. The trade-off is total privacy: your GIF is never uploaded, never logged, never stored on any third-party server. Closing the tab erases everything from memory immediately. For most short loops the wait is small, and for sensitive material — work captures, dashboards, private screen recordings — the privacy gain is well worth the few extra seconds.
Is my GIF uploaded to a server?
No. Everything runs entirely inside your browser tab using gifuct-js for decoding, the HTML5 Canvas API for pixel work, and gifenc for re-encoding. The file is decoded into local memory only, processed in the same tab, and the result is offered as a direct download. Nothing is transmitted to any server, no account is required, no analytics are tied to your file, and closing the tab discards every byte from memory.
How big a GIF can I process?
Up to 50MB and roughly 16 megapixels per frame, with a soft cap of about 600 frames. The limit exists because every frame needs to fit inside your tab's memory as full-resolution RGBA pixels (four bytes per pixel). Most short loops, screen recordings, and reaction GIFs sit comfortably under that ceiling. If your GIF is larger, run the GIF Compressor or GIF Frame Skipper first to bring it down before applying further effects.
How are colours quantized in the output?
gifenc builds a fresh palette per frame using a wu-quant algorithm with up to 256 colours. This keeps colour-shifting effects (fades, glitch, brightness) accurate even when the source palette was tiny. You can lower the colour count in the Color Reducer / Compressor / Lossy Compressor tools to trade colour fidelity for smaller files.
Are transparent backgrounds preserved?
Yes — gifuct-js gives us a per-frame alpha channel from the original GIF's disposal data, and we composite frames into RGBA buffers so transparency survives every effect. When you re-encode, gifenc writes a 1-bit transparent palette index whenever the source alpha was zero, so transparent regions remain transparent in the output.
Does the loop count carry over?
Yes — when the source GIF declares a loop count via the NETSCAPE2.0 application extension, we read it during decoding and write the same value into the output container. If the source has no loop block (a one-shot GIF), the output also plays once. Tools that explicitly let you change loop behaviour (Loop Editor, Boomerang, Player) override this and write whatever loop count you choose.
Which browsers are supported?
Recent Chrome, Edge, Firefox, Safari, and other Chromium-based browsers all work. The tool only relies on the standard HTML5 Canvas API, ArrayBuffer, and Blob URLs, all of which have been universally supported for over a decade. Mobile browsers work too, although large GIFs may take noticeably longer because phone CPUs are weaker than desktop CPUs.
Is there a watermark or sign-up wall?
No. The tool is completely free, requires no account, attaches no watermark, and shows no popup ads on your output. A small fair-use throttle runs in the background to discourage automated abuse, but it does not affect normal one-off conversions. The downloaded GIF is exactly what gifenc wrote out from your edited frames — nothing more, nothing less.
Why did GIF Color Palette reject my input?
Failures usually fall into one of three buckets: the input is in an unsupported format, the input is over the size cap, or the input is structurally malformed (a truncated download, a partial export, or a stream the engine does not recognise). The first two are easy to confirm — check that your file is one of GIF and that it is below 50 MB. For the third, opening the file in its native viewer first is the fastest way to confirm the source is intact.
How long does GIF Color Palette take to process a file?
Most jobs finish in seconds. Speed scales with input size and with how many CPU cycles your browser tab has available — the engine runs in your browser, so it shares resources with whatever else you have open. For inputs near the 50 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
Do I need a specific browser to use GIF Color Palette?
GIF Color Palette works in any modern browser released in the last few years — Chrome, Edge, Firefox, Safari, Brave, Arc and the major Chromium derivatives are all supported. The underlying engine relies on widely-supported web APIs, so there is nothing exotic to install. If you are on a very old browser version and the tool fails to load, updating to the latest release of your preferred browser is the only fix needed.
Can I use GIF Color Palette for commercial work?
GIF Color Palette can be used for personal and commercial work alike — there is no separate "business" licence to purchase. The output you generate is yours to use however you want, including in client deliverables, internal documents, or commercial products. Favtoo's only ask is fair, individual use; the tool is not designed to be embedded as a backend service or wrapped behind an API for resale.
How accessible is the GIF Color Palette interface?
GIF Color Palette uses native HTML controls wherever possible, which means keyboard navigation, focus rings, and screen-reader labels work the way the platform expects. The drop zone accepts files via the keyboard-accessible file picker as well as drag-and-drop, and result downloads use standard browser download flows. If you spot an accessibility gap, Favtoo treats it as a bug worth fixing.
Does GIF Color Palette need an internet connection to run?
Once the page is loaded, GIF Color Palette can complete jobs without an active internet connection — the engine is bundled with the page, so there is no per-job network call. The initial page load does require a connection (to fetch the static assets), but after that you can disconnect entirely and the tool will still work. This is a side-effect of the local-first architecture, not a deliberate "offline mode" feature.
Does GIF Color Palette reduce quality of the result?
GIF Color Palette is built to preserve quality wherever the underlying image format allows it. Operations that are mathematically lossless (e.g. structural transformations, lossless re-encoding) round-trip with no perceptible change. Operations that involve a lossy codec inevitably introduce small artefacts at the byte level, but the defaults aim at the sweet spot where output looks or sounds the same to a normal viewer or listener while still being meaningfully smaller or faster than the input.
Are there any hidden fees with GIF Color Palette?
GIF Color Palette is free to use. The processing runs in your browser, which keeps the per-user cost low enough that the tool can be offered openly. The download is the same file the engine produced — you can use it for as many runs as you need.
Does GIF Color Palette match what professional tools produce?
GIF Color Palette is built on standard browser APIs, which is the same class of engine used by professional image editing and conversion pipelines. For deterministic operations, the output is byte-identical to what an equivalent CLI run would produce; for operations involving a codec or a model, the result is well within the range of what comparable tools generate. If you have a specific reference output you need to match, run a small test job first to confirm the configuration produces what you expect.
