How to use AVIF Compressor

What the tool does, how to run it, and what to expect from the result.

How to compress an AVIF

To compress an image, upload one still AVIF to the AVIF Compressor and pick a preset: balanced for a safe size cut, smaller for a tighter result, or aggressive when minimum file size matters most. The tool re-encodes the image and shows the size delta so you can see exactly how much you saved.

When you are happy with the tradeoff, export the lighter AVIF. The whole process runs in your browser, so the original image is never uploaded and stays private on your device.

  • Upload one still AVIF
  • Choose balanced, smaller, or aggressive
  • Compare the size delta and export

Why this stays separate from recompression

Most people just want a smaller AVIF and do not need technical settings. The AVIF Compressor keeps that preset-driven job simple and fast, so a single choice gets you a lighter file without sliders or encoder jargon.

If you need finer control, the AVIF quality recompressor offers a manual quality slider for tighter tuning. The compressor is the right starting point when speed and simplicity matter more than precise control.

Tips

Getting a better result out of AVIF Compressor

Specific settings and thresholds, not general advice.

  • The presets are Balanced (quality 70), Smaller file (56) and Aggressive (42). Balanced is the honest default; Aggressive at 42 is for when a hard size limit matters more than fidelity.
  • AVIF holds up at much lower quality numbers than JPEG does. A quality of 56 in AVIF is not the disaster the same number would be in JPEG, which is exactly why the format is worth the encode time.
  • Do not compress an AVIF twice. It is lossy, so a second pass costs quality for progressively less size. Go back to the original PNG or JPG and encode once.
  • This is the preset-driven tool. If you want to set the exact quality number and compare the result, use the AVIF Quality Recompressor instead.
  • Encoding runs on your CPU, so a large image takes real seconds. Nothing is uploaded, and that is the trade.
Limits

What AVIF Compressor does not do

The honest boundary, so you do not lose time finding it yourself.

  • It does not resize or crop.
  • It cannot recover quality from an already-compressed AVIF. Each pass costs more.
  • It does not convert to another format.
  • It handles a still AVIF, not an animation.

Files & formatsAVIFAVIF (.avif) is a next-generation image format based on the AV1 video codec. It typically produces smaller files than JPEG or WebP at the same quality and supports transparency, HDR, and wide color — making it one of the most space-efficient formats available.General

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is this for animated AVIF too?

No. The AVIF Compressor handles still images only; the current AVIF tools do not process animated AVIF.

Should I use the quality recompressor instead?

Use the AVIF Compressor for quick preset-driven exports. Choose the AVIF quality recompressor when you want tighter manual control over quality.

Does my AVIF get uploaded?

No. Compression and export run entirely in your browser, so the original AVIF stays on your device and is never sent to a server.

Is the AVIF compressor free?

Yes. The AVIF Compressor is free to use with no signup, and everything happens locally in your browser.

How do I make an AVIF smaller?

Open it here and pick a preset: Balanced is quality 70, Smaller file is 56, and Aggressive is 42. Each is progressively lighter, and the encode runs in your browser with nothing uploaded.

Is a quality of 56 too low?

In JPEG it would be. In AVIF it is not: the format holds detail far better at low quality numbers, which is precisely why it is worth the extra encode time. Judge the preview, not the number.

Should I compress the same AVIF twice?

No. It is lossy, so a second pass costs more quality for less and less size. Go back to the original PNG or JPG and encode once, at the setting you actually want.

Should I use this or the AVIF Quality Recompressor?

Use this one for presets and speed. Use the Recompressor when you want to set an exact quality number, tune the encoder effort, and compare the result yourself.

Why does it take a few seconds?

AVIF encoding is genuinely expensive, and it runs on your own CPU rather than on a server. That is the price of the image never leaving your device.
