Convert PNG to AVIF
Updated Jul 2026
PNG is a lossless format used for screenshots, logos, and UI assets, while AVIF is a newer image format built for the web that shrinks file sizes dramatically. To convert PNG to AVIF, open the file in a converter and export it as AVIF. Doing this on your own computer means the image never has to leave your machine to be compressed.

How to convert PNG to AVIF
- Open Morphjet and drag in the PNG file, or a whole folder of them, at once.
- Choose AVIF as the output format, and set a quality level if you want to control the trade-off between size and detail.
- Convert. The AVIF files are written next to your originals, and nothing leaves your machine.
PNG vs AVIF: what actually changes
| PNG | AVIF | |
|---|---|---|
| File size | Larger, especially for photos and screenshots | Much smaller, often a fraction of the PNG |
| Quality | Lossless, pixel-perfect | Lossy by default, though very good at reasonable settings |
| Transparency | Yes | Yes |
| Compatibility | Opens everywhere, on every device and app | Supported by modern browsers, but older software and some apps can't open it |
| Best for | Screenshots, logos, UI assets, editing masters | Web images where load speed matters |
When to convert, and when not to
Convert PNG to AVIF when you're publishing images on a website and want them to load faster without a visible drop in quality, especially for large screenshots or photos.
Keep the PNG if you need the file to open reliably in older software, or if you're archiving a master copy you might edit again, since PNG's lossless nature and wide support make it the safer original.
Why not just use an online converter?
Online image compressors ask you to upload your file to their server, run the conversion there, and send it back, which means a copy of your screenshot or logo sits on a stranger's machine in the meantime. Converting PNG to AVIF on your own computer skips that step entirely. The file is compressed locally and the AVIF appears next to the original, with nothing sent anywhere.
Questions
Does converting PNG to AVIF lose quality?
Yes, a little, since AVIF is a lossy format by default. At sensible quality settings the loss is hard to notice, and the file can end up a fraction of the PNG's size.
Can AVIF keep transparency like PNG?
Yes. AVIF supports transparency, so logos and UI assets with transparent backgrounds convert without losing that.
Will every browser and app open an AVIF file?
Most current browsers and many apps support it, but some older software and devices still don't. If you need an image to open absolutely everywhere, PNG or JPG is the safer bet.
Why would I convert a screenshot from PNG to AVIF?
Screenshots as PNG can be surprisingly large. Converting to AVIF shrinks them a lot, which is useful if you're embedding a lot of screenshots on a page and want it to load quickly.
Can I convert PNG to AVIF without uploading it anywhere?
Yes. A desktop app like Morphjet does the conversion on your own computer, so the image never travels over the internet.
