About Color Depth Checker
Color Depth Checker performs color depth checker as a focused single-page utility. Generate a JavaScript snippet to detect color depth, HDR support, color gamut, and contrast preferences. Defaults are tuned for the common case so the first run is one click, with every option that matters exposed for the moments you need to fine-tune the result.
Architecturally, Color Depth Checker is a single-page client. The processing layer is standard browser APIs; the UI is a thin React shell on top. Inputs flow through the engine and the output is returned to the browser as a Blob you can save or copy. The 0 MB cap is the only hard limit and it exists to keep memory usage stable on every device.
Color Depth Checker parses your file with standard browser APIs entirely inside the browser, applies the options you selected, and returns a download. The processing has no network step, which means a slow or intermittent connection does not slow down the work — once the page is loaded, only your CPU and RAM are involved.
The heaviest users of Color Depth Checker tend to be product managers comparing options, teachers building resource lists and creators experimenting with formats. Each group brings slightly different expectations to the tool, but the same single-page architecture serves every one of them with the same response time.
The right moment to reach for Color Depth Checker is when you have a focused web and productivity utility job that fits inside a browser tab. Open the page, drop in the file or paste your input, choose the options that matter, and the tool returns the result.
A practical note on limits: Color Depth Checker accepts inputs up to 0 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, Color Depth Checker sits next to Screen Resolution Checker, Device Pixel Ratio Checker, and Browser Feature Detector. None of them depend on each other — you can use Color Depth Checker on its own — but together they cover the common variations of the task this page exists to handle.
Color Depth Checker is honest about scope: it handles a single, well-defined web and productivity utility step. Specialist edge-case work — uncommon formats, very large inputs, or pipelines that need scripting — is what dedicated desktop apps are for. This page handles the common case quickly.
Color Depth Checker returns the result as a download. If you are running multiple jobs, the output names will not collide as long as the input names differ. You can re-run with different settings as many times as you like; each run produces a fresh file with no caching trickery in between.
Some background on the design choices behind Color Depth Checker: every option you see on the page is there because a real workflow needs it, and every option that is not shown has been deliberately omitted to keep the common case fast. The bias is toward minimal-but-complete.
Color Depth Checker 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.
If you want to get the most out of Color Depth Checker, three small habits help. Drag-and-drop is faster than the file picker once you get used to it. The keyboard shortcut for downloading the result is whatever your browser uses for "save link as," because the result is a normal download. And if you are working on a sensitive file, processing in an Incognito or Private window is a good extra layer — it leaves no trace in browser history when the tab closes.
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).
Color Depth Checker 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
- 1Open the Color Depth Checker workspace above. The interface is a single page, so there is nothing to navigate.
- 2Drop a web utility file onto the upload area, or click to pick one from your device.
- 3Tweak the controls if the defaults are not quite right for your input. The options are kept short and labelled in plain language.
- 4Hit the run button. standard browser APIs does the work in your browser tab.
- 5Save the output when it is ready.
- 6Repeat the process for additional inputs whenever you need to. The page stays loaded, so subsequent runs are quick.

FAQ
What is color depth?
Color depth is the number of bits used to represent each pixel. 24-bit means 16.7 million colors.
HDR support?
The script checks for high dynamic range support via the dynamic-range media query.
Color gamut?
Detects sRGB, Display P3, and Rec2020 gamut support for wide color range.
Private?
Yes — runs locally.
Dark mode?
The script also checks prefers-color-scheme for dark/light mode preferences.
Accessibility?
Contrast preference (more, less, custom) is detected for accessibility-aware designs.
Does Color Depth Checker reduce quality of the result?
Color Depth Checker is built to preserve quality wherever the underlying web utility 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.
Can I use Color Depth Checker offline?
Once the page is loaded, Color Depth Checker 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 Color Depth Checker match what professional tools produce?
Color Depth Checker is built on standard browser APIs, which is the same class of engine used by professional web and productivity utility 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.
Does Color Depth Checker have an API?
Color Depth Checker is a browser-only tool by design and does not expose a hosted API. The reason is the same as the privacy story: there is no Favtoo backend doing the work, so there is no service to call. If you need to script the same transformation, the underlying engine (standard browser APIs) is open-source and can be used directly from your own code.
Which file formats does Color Depth Checker accept?
The accepted formats are listed in the upload area on the tool itself. If your input is in a format that is not directly supported, convert it first using one of Favtoo's converter tools — every Favtoo converter outputs a file that is a clean input to the next tool in the chain.
Is Color Depth Checker keyboard accessible?
Color Depth Checker 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.
How long does Color Depth Checker 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 0 MB ceiling, expect anywhere from a few seconds to roughly a minute on a typical laptop. Closing other heavy tabs noticeably speeds things up.
Does Favtoo keep a copy of files I process with Color Depth Checker?
Favtoo keeps no copy of your file because Favtoo never receives your file. Color Depth Checker runs entirely in your browser, the input is held only in your tab's memory, and closing the tab discards it. There is no opt-in cloud history, no "recent jobs" panel synced to an account, and no server-side retention to configure — the architecture simply has nowhere for your file to be stored.
