AVIF compressor

Why compress AVIF?

AVIF can be tiny, yet camera and design exports are not always tuned. Hitting a compression percent gives a predictable byte budget for AVIF delivery without leaving the browser.

What changes in the file

• Output stays AVIF
• Encoder quality is searched to approach your size target
• EXIF and other metadata are not preserved through the WASM encode path
• If quality alone cannot hit the budget, the image is scaled down and re-encoded

How to compress AVIF

1. Open the AVIF compressor and drop one or more images (any supported source format).
2. Choose a compression percent (or a preset). The tool computes target size as original × (1 − percent/100).
3. Start compression. Encoding runs locally with WASM codecs and downloads as AVIF.

About AVIF

AVIF is a next-generation image format based on the AV1 video codec. It typically yields smaller files than WebP or JPG at similar quality and supports transparency and high bit depth.

FAQ

Does this AVIF compressor upload my files?

No. Detection, decode, and WASM encode all run in your browser. Formatly never receives the image bytes for compression.

What does the compression percent mean?

It is a size budget, not a vague quality label. 90% compression on a 50 MB file targets about 5 MB (keep 10% of the original size). The encoder searches quality and, if needed, scale to approach that budget.

Can I compress other formats into AVIF?

Yes. Drop JPG, PNG, WebP, HEIC, and other supported sources; the page exports AVIF. On this page the output format is fixed to AVIF.
