PDF to AVIF
Turn PDF pages into AVIF images — right in your browser, nothing uploaded.
Drag & drop your PDF here, or click to choose. Everything runs in your browser — nothing is uploaded.
This free PDF to AVIF converter renders each page of your document and encodes it as AVIF, the AV1-based format that is typically 30-50% smaller than JPG at the same visual quality. No browser can create AVIF on its own, so the page loads a small WebAssembly encoder when you press Convert — on your device, with nothing uploaded.
Frequently Asked Questions
How do I convert a PDF to AVIF?
Drop your PDF onto the box above, choose a resolution and quality, then press Convert. Every page is rendered and encoded as AVIF, shown with its file size and a Download button, or you can save the whole set at once.
Are my files uploaded to a server?
No. The file is decoded and re-encoded directly in your browser using JavaScript and WebAssembly, and never leaves your device. That is what makes it safe for private photos, client work and anything confidential, and it is why the tool keeps working with your network disconnected once the page has loaded.
Why is AVIF so much smaller than JPG?
AVIF uses the AV1 video codec’s intra-frame compression, which is far more sophisticated than JPG’s 1992-era approach — it predicts blocks from their neighbours and adapts the transform to the content. For photographic pages the saving is commonly 30-50% at matching quality.
Will AVIF open everywhere?
It opens in every current browser — Chrome, Edge, Firefox and Safari all decode AVIF. Older desktop image viewers and some older phones may not, so keep a JPG or PNG copy if the file has to open on unknown software.
Is there a limit on pages or file size?
None imposed by us, because nothing is uploaded — the only constraint is your device’s memory. AVIF encoding takes roughly half a second per page, so a very long document is best done on a desktop rather than a phone.
Does this work on Windows, Mac, iPhone and Android?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install and no account needed. Chrome, Edge, Firefox and Safari are all supported.
