Compress AVIF Images
Re-encode AVIF for tighter file size — the modern format with the best compression ratios.
Your images stay on your device. Nothing is uploaded.
AVIF delivers smaller files than WebP at equivalent quality and is now supported across Chrome, Firefox, Safari, and Edge. If your AVIF files are coming out larger than expected, the encoder quality is usually the culprit — re-encoding at a slightly lower quality typically halves the file size with no perceptible difference.
Compression remains client-side. For converting other formats into AVIF, use the dedicated AVIF converter.

Frequently asked questions
- How do I compress a AVIF image?
- Drag and drop your AVIF file (or click to select) and the compressor reduces its size automatically using the pre-tuned settings on this page. Adjust the quality slider, max dimension, or output format for a stronger or gentler compression. Everything runs in your browser — your file never leaves your device.
- Does compressing a AVIF reduce quality?
- AVIF's quality scale is non-linear — q60 in AVIF often matches q85 in JPEG visually. The default reflects this; the slider gives you fine control. You can preview before downloading and tune the quality slider until the size and quality balance feels right.
- Is the AVIF compressor free?
- Yes. Image Compressor is free, requires no signup, and has no upload limits. For batches, use the bulk compressor.
- Are my AVIF files uploaded to a server?
- No. Compression happens entirely in your browser using the Canvas API. Files never touch our servers — that is what makes the tool both private and fast.
- What is the largest AVIF I can compress?
- Single uploads are capped at 25 MB to keep the tool responsive in the browser. Very large files may be slower because compression uses your device's memory and CPU rather than a server.
