Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To inspect an image, upload one AVIF to the AVIF Alpha Checker and switch between the RGB, alpha, and alpha-mask views. The alpha and mask views reveal exactly which areas are transparent, translucent, or opaque, which the normal RGB preview alone cannot show.
After analysis, the tool reports the percentage of transparent, translucent, and opaque pixels, giving you a definitive answer on whether the AVIF carries real transparency. If you need a visual record, export the current alpha view as a PNG.
An AVIF can technically support an alpha channel and still have messy edges or no meaningful transparency at all. The AVIF Alpha Checker makes that easy to verify before the asset moves downstream into a design, sticker, or web workflow that depends on clean transparency.
Because the analysis runs entirely in your browser, the AVIF is never uploaded to a server. You get a private, on-device check that is safe to run on client assets and unreleased graphics.
Short answers for the questions people usually have before trying a utility like this.
No. The AVIF Alpha Checker is an inspection-first tool. It does not modify the source AVIF; the only export is a PNG of the current alpha preview.
Yes. After analysis the tool reports transparent, translucent, and opaque pixel percentages, giving a definitive answer on whether the AVIF has meaningful alpha.
No. The AVIF Alpha Checker runs entirely in your browser, so the file stays on your device and is never sent to a server.
Yes. It is free to use with no signup, and all inspection and PNG export happen locally in your browser.
Every tool on Cleanor is free with no sign-up, no credits, and no limits. Files are processed privately in your browser. Looking for on-device phone cleanup and Premium features? That lives in the Cleanor app.
Confirm whether an AVIF really contains meaningful alpha, inspect the alpha render, and export the current view as PNG.
This browser cannot process AVIF locally yet. Use a modern Chromium or Safari build with ImageDecoder and OffscreenCanvas support.
