Convert AVIF to WebP
Got an AVIF that something won’t open? Convert it to WebP in your browser. WebP is supported almost everywhere AVIF still isn’t — older editors, apps and services — while staying far smaller than JPG or PNG, and the conversion never leaves your device.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
Small files, broader support
AVIF gives the smallest files, but it is also the newest format, so some editors, CMSs and messaging apps still can’t read it. WebP has had years longer to spread and works in nearly all of them, while keeping most of AVIF’s size advantage over the old formats. Converting AVIF to WebP is the practical move when a tool rejects your AVIF but you don’t want to balloon it back up to PNG.
A clean, local re-encode
Transparency is preserved in the switch, and you choose lossy WebP for the smallest result or lossless when every pixel must survive. Because the decode and re-encode both happen in your browser, even AVIF files that your operating system’s preview can’t show are converted on your device — no upload, no waiting on a server, no limits on how many you run.
Frequently asked questions
- Which formats are supported?
- You can convert to and from JPG, PNG, WebP, AVIF and BMP, and convert from HEIC/HEIF (iPhone photos). Browsers cannot create HEIC files, so HEIC is input-only. Output formats your browser cannot encode are detected and disabled automatically.
- Can I convert HEIC to JPG?
- Yes. Drop in a HEIC photo from an iPhone and choose JPG (or PNG/WebP). The HEIC file is decoded locally in your browser with a bundled decoder — it is never uploaded anywhere.
- Is transparency preserved?
- Yes, when converting to a format that supports an alpha channel (PNG, WebP, AVIF). For formats without transparency (JPG, BMP), you can pick a background color for transparent areas.
- Is my image uploaded?
- No. Conversion runs entirely in your browser — your images never touch a server.
- What is AVIF and should I use it?
- AVIF produces the smallest high-quality files. Encoding support varies by browser, so PixelVault enables it only when your browser can create AVIF files.
- Can I convert many images at once?
- Yes. Batch-convert a whole folder of images and export them together as a ZIP.
