JPG to AVIF Converter

Add your images — drag in JPG or PNG files, or click to browse.

Set the quality — choose a quality level; lower means smaller files.

Convert and download — save each AVIF, or click Download All as ZIP.

Yes. The page carries its own AVIF encoder (libavif, compiled to WebAssembly), so it doesn't need the browser to support making AVIF. The encoder is a 3.5 MB download the first time you convert. After that, a large photo takes around 10 seconds on a phone. Nothing is uploaded.

Usually, yes — noticeably. At a comparable visual quality, AVIF often produces files meaningfully smaller than JPG thanks to the AV1 codec. That's why it's attractive for websites where every kilobyte affects load time.

No. Converting can't restore detail the original JPG already lost to compression — it only re-encodes the current pixels more efficiently. You get a smaller file of the same visual quality, not a sharper image.

Most modern browsers display AVIF now (Chrome, Firefox, Edge, and recent Safari). For older browsers, keep a JPG or WebP fallback. Support for viewing is broader than support for encoding it in the browser.

Yes — this tool accepts JPG and PNG input and outputs AVIF. PNG sources keep their transparency in the AVIF. For a dedicated PNG starting point, the PNG to AVIF tool is tuned for that.

For web photos, a mid-to-high quality gives a big size saving with little visible loss. Lower it further for non-critical images, or raise it for hero images. Compare the result against the original before publishing.

No. The converter runs entirely in your browser using the HTML5 Canvas, so your files are processed on your own device and never uploaded. Nothing is stored once you close the tab. That keeps your images private and makes conversion fast, because there's no upload or download to a server.

Yes. Drag in a whole batch and the tool converts them all locally. Download each result from its card, or click "Download All as ZIP" to save the entire set in one folder. There's no cap on the number of files beyond your device's memory.

Yes. It runs in your phone's browser with nothing to install, so you can convert files on Android or iOS and download the result. Small batches convert quickly; very large or high-resolution sets use more memory and are smoother on a computer, but everyday conversions work fine on mobile.

There's no artificial cap or paywall, because nothing is uploaded — the work happens on your device. The practical limit is your device's memory. A large batch of high-resolution images uses more memory and is smoother on a computer, but everyday conversions run quickly even on a phone.

No. There's nothing to download or install and no account to create. The converter runs in any modern web browser, on any operating system, so you don't need a desktop image editor or codec. Just open the page, add your files, and convert.

Yes, it's completely free with no account and no limits, and it adds no watermark — what you download is clean. Because everything runs locally in your browser, there's no paywall and no usage cap.

Yes. Once the tool has finished, a Send to button sits beside Download. Pick another tool and it opens with the result already loaded: no second download, no re-upload. Suggested next steps for this AVIF image: Image Compressor, Image Resizer, Image Cropper and Merge Images. The handover stays on your device, held in this browser for a few seconds while the next tool opens, then deleted.
