Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To recompress an image, upload one still AVIF to the AVIF Quality Recompressor, then move the manual quality slider and set the effort-style hint that guides the encoder. The preview and size delta update so you can see the exact tradeoff between visual quality and file size before you commit.
When the balance looks right, export the recompressed AVIF. The tool keeps the format as AVIF rather than converting it, so you stay in the same efficient format with a smaller, cleaner result.
The AVIF Compressor is meant to be practical and fast, using simple presets for people who just want a smaller file. The AVIF Quality Recompressor is for users who already know they want tighter manual control over AVIF quality and are willing to trade a little speed for precision.
Because recompression and export happen in your browser, the AVIF is never uploaded. That keeps your asset private while you fine-tune the quality on your own device.
Short answers for the questions people usually have before trying a utility like this.
Yes. The goal is still-image AVIF-to-AVIF recompression, not format conversion, so your output stays in the AVIF format.
Yes. Recompression, preview, and export all happen in your browser, so the AVIF is never uploaded to a server.
Use the recompressor when you want a manual quality slider and precise control. Use the AVIF Compressor for quick, preset-driven exports.
Yes. It is free to use with no signup, and all tuning and 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.
Fine-tune AVIF quality, adjust the runtime effort hint, and compare the resulting file size before you download it.
This browser cannot process AVIF locally yet. Use a modern Chromium or Safari build with ImageDecoder and OffscreenCanvas support.
