Convert PNG to AVIF

Convert your images

Add one image or a whole batch — every conversion happens right here on your device.

Controls the size-versus-quality trade-off for JPG, WebP, and AVIF — higher looks closer to the original, lower makes a smaller file.

How it works

  1. Drop your PNG files here, or select a whole folder.
  2. Each PNG is decoded and re-encoded as AVIF — right in your browser, transparency intact.
  3. Adjust the quality slider; AVIF encoding takes a little longer than other formats, this is normal.
  4. Download the AVIF files individually, or as one ZIP.

AVIF is the biggest jump in compression efficiency since WebP, and PNG is exactly the kind of source that benefits most — large, flat-colour graphics, illustrations, and screenshots can shrink dramatically once re-encoded as AVIF. This tool converts PNG to AVIF entirely inside your browser, with transparency preserved. One thing to expect: AVIF encoding takes noticeably longer than JPG or WebP, especially on a phone — for a batch of large images, give it a few extra seconds per file rather than assuming the tool has stalled.

Why use convert.pics?

  • Often the smallest file of any format here, especially for flat-colour graphics.
  • Transparency preserved, same as the source PNG.
  • No upload: encoding runs locally, however long it takes.
  • Batch conversion for a whole folder of images at once.

Frequently asked questions

How much smaller is AVIF than PNG?

Often dramatically smaller, especially for large, flat-colour graphics and illustrations — AVIF's compression is built for exactly this kind of content and frequently beats PNG by a wide margin at visually equivalent quality.

Does AVIF support transparency?

Yes, AVIF has a full alpha channel, so a PNG's transparency carries over to the AVIF output without any loss or workaround needed.

Do all browsers support AVIF in 2026?

Every current version of Chrome, Firefox, Edge, and Safari supports AVIF. The gaps that remain are mostly older desktop software and some image editors, not browsers.

Why does AVIF encoding take longer than other formats?

AVIF's compression algorithm is more computationally intensive than JPG's or WebP's — that's part of why it compresses so well. On a phone or an older laptop, a batch of large PNGs may take noticeably longer to encode; that's expected, not a hang.

Live request log

Every network request this page and its conversion workers have made since the page loaded. None of them carries image data.

No network requests recorded yet.

    Codec files are WebAssembly decoders. They are downloaded to your device once and then run inside your browser.

    Airplane-mode challenge

    Do not take our word for it — cut the connection and watch the converter keep working.

    1. Load this page once, then switch on airplane mode or turn off Wi-Fi.
    2. Drop an image into the converter and convert it as usual.
    3. The conversion finishes and the download works. A converter that uploaded your files could not do that.

    Check it in your browser's developer tools

    1. Press F12 (⌥⌘I on macOS) and open the Network tab, then reload the page.
    2. Convert an image and watch the requests that appear.
    3. You will see our scripts and codec files being downloaded, and no request that uploads your image — check the size and payload column of every entry.

    Background caching by the service worker also shows up in DevTools: it downloads our app files for offline use. It never uploads anything.
