AVIF (a next-generation image format with tiny files) and WebP (a modern, efficient web image format). This free tool converts AVIF to WEBP directly in your browser, so your file never leaves your device. No install and no sign-up needed.
Batch conversion, ZIP download and quality control
- Convert many files at once — drop or pick several AVIF files and they are converted one after another.
- When you convert two or more files, the results are bundled into a single ZIP so you download everything in one click.
- Adjust quality and size: lower the quality or resize to make the WebP files smaller. The setting applies to every file in the batch.

Frequently asked questions
Is my AVIF file uploaded when I convert it to WebP?＋
No. The conversion runs entirely in your browser using your device, so your file is never sent to any server.
Will the quality drop when I convert AVIF to WEBP?＋
Both AVIF and WebP are lossy formats, so re-encoding may slightly reduce quality.
Can I convert several AVIF files to WebP at once?＋
Yes. Add multiple files and they are converted one by one in your browser. A single file downloads directly; two or more are packed into one ZIP. If one file fails, the others still convert.
Is it free? Do I need to sign up?＋
Yes, it is completely free — no sign-up, no install and no watermark.
Is there a file size limit?＋
You can convert files up to 30 MB. Everything is processed on your device, so very large files depend on your available memory.
Can I convert the other way, from WebP back to AVIF?＋
That direction is not available right now. AVIF can still be converted to several other formats.
