FAQ
- What is the maximum file size?
- 3 MB. This is set by the Vercel free tier request body limit. For larger images, clone the repo and run locally — there is no size cap when self-hosted.
- Does conversion affect image quality?
- Lossless formats (PNG, TIFF) preserve every pixel. Lossy formats (JPEG, WebP, AVIF) use the quality slider — 80 is a good default that balances file size and visual fidelity.
- Why convert to WebP or AVIF?
- WebP is 25–35% smaller than JPEG/PNG at equivalent quality and is supported by all modern browsers. AVIF is 50% smaller still but takes longer to encode. Both are great for web delivery.
Why convert AVIF to GIF?
GIF preserves every pixel without quality loss, useful when you need a lossless archive copy of a AVIF image. GIF is often used as a target when you need wide compatibility — it is supported even in environments that do not accept WebP or AVIF.
- –Legacy compatibility — GIF is supported in nearly every image viewer and email client, including ones that reject WebP.
- –Batch conversion of AVIF files in a CI pipeline using the REST API: POST /api/image-converter.
- –Quick one-off conversion without installing software — everything runs in your browser.
About AVIF and GIF
AVIF is based on the AV1 video codec and achieves up to 50% better compression than JPEG. It is supported by Chrome, Firefox, and Safari.
GIF supports animation and transparency but is limited to 256 colours. Best for simple animations and pixel art.
Quality note: AVIF is lossy; GIF is lossless. Converting to GIF will not restore quality lost during the original AVIF compression, but no additional quality loss occurs in this conversion.

- Does converting AVIF to GIF reduce quality?
- GIF is lossless, so no quality is lost in the conversion. The file may be larger than a lossy alternative.
- Can I convert multiple files at once?
