How to convert AVIF to WebP
- Drag your AVIF files into the box above or click “Choose files” (folders and pasting from the clipboard work too).
- WebP is preselected as the output format; adjust quality, size and target file size if you like.
- Press “Start converting”; files are converted in your browser, in parallel.
- Download the files one by one or grab them all as a ZIP.
Why convert AVIF to WebP?
At the same visual quality WebP is usually clearly smaller than JPG and PNG, which improves page speed and Core Web Vitals.
Some older software cannot open AVIF; converting makes the images usable everywhere.
AVIF vs WebP
| AVIF | WebP | |
|---|---|---|
| File extension | .avif | .webp |
| Compression | Lossy + lossless | Lossy + lossless |
| Transparency | Yes | Yes |
| Animation | Limited | Yes |
| Typical file size | Smallest | Very small |
| Support | Current browsers | All modern browsers |
| Best for | bandwidth-sensitive web pages and high-resolution photographs | websites, blog images, smaller replacements for JPG and PNG |
AVIF is a next-generation format based on the AV1 video codec; at equal visual quality it is usually smaller than JPG and WebP. WebP is a modern format from Google that offers lossy and lossless compression, transparency and animation. Some older software and print/office tools cannot open WebP.
Tips for the best results
- For most photos a quality of 80–85 is visually indistinguishable while making the file much smaller. If you have a size limit, use the “Target file size” option.
- For the web, limiting the width to 1600 pixels cuts file size a lot while keeping visual quality (Resize section).
- Metadata such as GPS location and camera details (EXIF) is always removed from the output.
Privacy and security
Conversion runs entirely in your browser (using WebAssembly); your images are never uploaded to our server and never leave your device. The server only receives anonymous counters that contain no file names or content (source/target format, size, duration). Metadata such as location and camera details is always stripped from the output.
