About GIF to APNG
Convert animated GIF to animated PNG (APNG) for higher color fidelity on supporting viewers.
The GIF is decoded into composited frames and re-played onto a canvas while the browser's native MediaRecorder API encodes the live stream into animated PNG (APNG / WebM fallback). This avoids loading FFmpeg WASM (which would download tens of MB) and stays fully client-side.
Note: animated WebP and APNG do not have a universal browser encoder. We export a WebM-VP9 stream renamed to your chosen container — most players accept it. For strict APNG / WebP, use a desktop tool.

About GIF to APNG
GIF to APNG is the kind of utility you bookmark and reach for when you need it. Convert animated GIF to animated PNG (APNG) for higher color fidelity on supporting viewers. It loads quickly, works on any modern browser, and produces a result you can download or copy in a single click.
Typical users of GIF to APNG include e-commerce owners cleaning product shots, developers preparing UI screenshots and illustrators packaging artwork. The thread connecting all of them is the same: a focused image editing and conversion task that fits cleanly into a browser tab and benefits from a tool with sensible defaults and minimal setup.
GIF to APNG is a static page plus a client-side engine. The browser does the work; there is no separate backend in the loop for the actual processing. That architecture is why the tool starts immediately, why it does not depend on the load on a remote service, and why running multiple jobs in a row does not slow it down.
Behind the controls you see, standard browser APIs is doing the actual image editing and conversion. GIF are first-class formats and the engine produces a deterministic output for any given input + options combination — useful when you need to re-run a job and expect identical results.
GIF to APNG is shaped for the gap between "I'll do it by hand" and "I'll script it." When the job is small enough that automating it would take longer than doing it, but annoying enough to want a focused tool — that is the situation this page is built for.
If your task needs more than one step, chain GIF to APNG with APNG to GIF, GIF to WebP, and GIF Compressor. Each tool produces output that is a clean input to the next, so multi-step workflows are just a matter of opening the next tool in a new tab and continuing.
The output handed back by GIF to APNG is `{name}-edited.gif`. If you would prefer to keep the result in the browser instead of downloading it, you can copy it from the result panel and paste it directly into another tab — useful when the next tool in your workflow expects pasted text rather than a file.
A practical note on limits: GIF to APNG 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.
GIF to APNG is built around steady iteration on a small set of options rather than feature creep. Every additional setting attracts a slightly different audience, but a long settings panel makes the common case slower for everyone. The current controls reflect what users of the tool actually use.
Some context on why GIF to APNG exists in this form: modern File APIs, high-performance JavaScript engines, and well-maintained open-source libraries now make it possible to perform image editing and conversion work entirely in the browser. GIF to APNG is built on top of that capability, which is why a single page can host the full pipeline.
Useful patterns when working with GIF to APNG: keep the input file open in another tab so you can compare against the result; give the output file a descriptive name when saving so you can find it later (the default name is sensible but generic); and treat each run as independent — the tool has no concept of "history", which means you cannot accidentally pollute one job with leftovers from another.
For most failure modes, refreshing the page and re-running the job is enough — the engine has no persistent state to corrupt. If the same input fails twice in a row, the input itself is most likely the problem (a truncated file, an unexpected variant of the format, or a stream the engine does not recognise).
GIF to APNG produces deterministic output: the same input plus the same options always produces the same result. That predictability matters when the result has to match an upstream specification or be reproducible later.
GIF to APNG is one of many single-purpose tools in the catalog. Each is built around the same single-page model. Use this one, close the tab, and come back the next time you need the same job done. None of the tools require prior knowledge of the others — each page is self-contained.
How it works
- 1Reach the GIF to APNG page in your browser to begin.
- 2Drop a GIF file onto the upload area, or click to pick one from your device.
- 3Pick any non-default settings you need. Most users leave the defaults alone for the first run and only revisit if the result needs tuning.
- 4Click to start the job. The engine (standard browser APIs) processes the input in the page; you can watch the progress indicator until it completes.
- 5Download the result as `{name}-edited.gif`. The file is generated in your browser and saved through your normal download flow.
- 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.

FAQ
APNG vs GIF size?
APNG can be larger because it stores truecolor frames — prioritize quality over smallest bytes.
Where is APNG supported?
Firefox, Safari, and Chromium-based browsers generally display APNG; always test your target audience.
Does Discord show APNG?
Platform support changes — preview in the exact app you plan to share before relying on APNG.
Disposal methods?
Exports pick disposal modes that avoid ghosting between frames when viewers composite animations.
Older Internet Explorer?
IE never supported APNG; use GIF or MP4 fallbacks for ancient environments.
Private?
Yes — decoding and encoding occur locally in your browser.
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 use GIF to APNG instead of a paid online tool?
Desktop apps usually have more advanced features but require installation, maintenance and (often) a licence. Paid online tools are convenient but route your file through their servers and gate downloads behind accounts. GIF to APNG sits in between: free, instant, and private, but intentionally narrow in scope. For one-off jobs and the common image editing and conversion operations, it is usually the lowest-friction choice; for highly specialised work, a dedicated app is still the right answer.
Can I self-host GIF to APNG for my team?
GIF to APNG is a static page running an open-source engine in your browser, so a typical corporate firewall does not get in the way as long as it allows JavaScript to load from Favtoo. For teams that need to host it themselves on an internal network, the underlying engine (standard browser APIs) is open-source and can be packaged into a private build with the same behaviour. Reach out via the Contact page if that is something you are exploring.
What permissions does GIF to APNG need to function?
GIF to APNG only needs the standard web platform — file picker access for the inputs you choose to load, and optionally clipboard access if you copy the result rather than downloading it. There is no microphone, camera, geolocation or background-permission request, because none of those are needed for the work the tool does.
Are there any hidden fees with GIF to APNG?
GIF to APNG 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.
How accessible is the GIF to APNG interface?
GIF to APNG 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 to APNG reduce quality of the result?
GIF to APNG 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.
Which browsers are supported by GIF to APNG?
GIF to APNG 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.
