Overview

``text JPG to AVIF converts JPG (and PNG) images into AVIF, a next-generation format with the best compression for the web. Convert a batch with a quality slider and download as a ZIP — all in your browser. AVIF output depends on your browser's encoder support. ``

```text AVIF gives smaller files than JPG at the same quality, which speeds up websites. This tool converts your JPGs (and PNGs) to AVIF locally so you can serve leaner images.

One honest note: creating AVIF files relies on your browser's built-in encoder, and not every browser can encode AVIF. If conversion doesn't produce a file, use a current version of Chrome or Edge, or convert to WebP instead. ```

Frequently Asked Questions

Will AVIF output always work in my browser?

Not always. Creating AVIF files relies on your browser's encoder, and some browsers don't support encoding AVIF yet. A current version of Chrome or Edge is the safest choice. If conversion doesn't produce a file, convert to WebP instead, which every modern browser can create.

Is AVIF smaller than JPG?

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.

Will converting improve my JPG's quality?

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.

Do all browsers display AVIF?

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.

Can I convert PNG to AVIF here too?

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.

What quality should I pick?

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.

Are my images uploaded to a server?

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.

Can I convert several files at once?

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.

Does it work on a phone?

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.

Is there a limit on file size or number of files?

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.

Do I need to install any software?

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.

Is it free, and is there a watermark?

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.
