Convert AVIF to WebP
AVIF and WebP solve the same problem, smaller images on the web, but they are a generation apart in tooling support. AVIF usually wins on raw compression, while WebP has had a decade for editors, CMSs, plugins and upload forms to catch up. Converting AVIF to WebP is the pragmatic trade: you give up some file size and get a format that the rest of your stack will actually accept.
Drop your AVIF files below and download WebP in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.
No upload. Works with your network switched off. Check it yourself, or read what actually happens to your file.
Why convert AVIF to WebP?
The usual trigger is a CMS or marketplace that rejects an AVIF upload but happily takes WebP, or an image pipeline that was built before AVIF existed. Because both formats support transparency and both are designed for the web, this is one of the few conversions where almost nothing about the image has to be compromised.
AVIF is based on the AV1 video codec and reaches even smaller files than WebP at the same visual quality. All modern browsers can display it, but many image editors and older tools cannot open it yet, which is the main reason people convert AVIF to an older format.
Google designed WebP to replace both JPG and PNG on the web, and it typically compresses 25 to 35 percent smaller at similar quality. It handles both lossy and lossless modes and supports transparency. Support is excellent in browsers but still patchy in older desktop software.
What this converter does to your AVIF file
Your browser decodes the AVIF and re-encodes it as WebP through the Canvas API. Both formats carry an alpha channel, so transparency survives the round trip intact. WebP is re-encoded rather than repackaged, so this is a lossy step: the output is a new compression of the decoded pixels, not a copy of the original AVIF data.
AVIF vs WebP at a glance
| AVIF | WebP | |
|---|---|---|
| Full name | AV1 Image File Format | WebP image |
| Compression | Lossy or lossless | Lossy or lossless |
| Transparency | Yes | Yes |
| Best for | Next generation web images | Modern websites and apps |
What changes when you convert AVIF to WebP
| What happens | |
|---|---|
| Image quality | Reduced. AVIF is already lossy and WebP compresses again, so this is a second encode. Nothing is recovered, and at low quality settings the losses stack. |
| Transparency | Kept. WebP stores an alpha channel, so cut-out backgrounds and soft edges survive. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the WebP file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not preserved. An animated AVIF produces a single still frame. |
| File size | Smaller in almost every case, which is the reason for the conversion. How much smaller depends on the picture, so no figure is quoted here. |

Frequently asked questions
Will the WebP file be bigger than the AVIF?
Usually yes. AVIF generally reaches smaller files than WebP at comparable visual quality, so converting to WebP typically costs you some file size. You are trading bytes for compatibility with older software.
Does transparency survive AVIF to WebP?
Yes. Both AVIF and WebP support a full alpha channel, so transparent areas stay transparent and are not flattened onto a background colour.
What is an AVIF file?
AVIF is a next generation format with excellent compression, increasingly used on modern websites.
What is a WebP file?
WebP is a modern format from Google that compresses smaller than JPG and PNG while keeping quality.
Is it free to convert AVIF to WebP?
Yes. There are no limits, no watermarks and no account needed. Convert as many AVIF files as you like.
Are my files private?
Completely. Your AVIF files never leave your browser and are never uploaded to a server, so your images stay on your device.
