Why convert PNG to AVIF
- Transparent web graphics and product cut-outs that are too heavy as PNG.
- Screenshots for documentation sites that serve AVIF.
How to convert PNG to AVIF in ConvertX

Open Image Converter
On the Home screen tap Image Converter.

Tap "Select image files" and pick the PNG images (.png). On desktop you can also drag them in from Explorer or Finder.
- 3
Choose AVIF as the target
In the output format list choose AVIF.
- 4
Optional settings
Add a rename pattern (use {name} for the original file name), turn on "Keep photo details" if you want camera and location data copied into JPG, PNG or WebP output, and pick an output folder (Android default: Pictures/ConvertX).
- 5
Start the batch
Tap "Convert N images". The Queue opens and processes them in order; you can stop one file or the whole batch.

Find the results
When the batch finishes, the summary shows the files converted and the space saved. Tap View Library to browse them, or find them in the output folder.
What to know before you convert
- AVIF is lossy at the quality you choose; fine text in screenshots can soften at Strong. Use Light.
- ConvertX cannot open AVIF afterwards; keep the PNG as the editable master.
- Browser support is current Chrome, Firefox, Safari 16.4+ and Android 12+; older viewers show nothing.

PNG: Lossless with transparency. Perfect for graphics, wasteful for photos. AVIF: The newest format, smallest files, still not opened by everything. ConvertX writes it but cannot read it.
Nothing is uploaded
ConvertX converts on the device. There is no server, no account and no file size or count limit beyond your storage. Location and camera details are removed from every output unless you turn on "Keep photo details" (AVIF output never carries them in ConvertX).
Frequently asked questions
Does PNG to AVIF keep transparency?
Yes, full and partial.
AVIF or WebP for transparent graphics?
AVIF is smaller; WebP opens in more places. For icons and UI, lossless WebP is often the safer choice.
Why is the AVIF not much smaller than my PNG?
Flat graphics with few colours already compress well in PNG. The big savings are on photographic content.
