Download your new AVIF file immediately. Multiple outputs pack into a single ZIP archive.
Why convert PNG to AVIF
PNG is a lossless raster format known for pixel-perfect quality plus full alpha transparency, while AVIF is a next-gen image format valued for excellent compression at high visual quality. Converting PNG to AVIF is the practical fix when a workflow expects AVIF — for example performance-minded sites that already support modern formats — but your file still lives as PNG. Browser Convert performs that swap entirely in your browser so the pixels never upload to a remote converter.
When to use this tool
- A tool, form, or teammate asked for AVIF, but you only have PNG.
- You are optimizing for performance-minded sites that already support modern formats instead of staying in PNG.
- PNG’s limits (larger files than JPG or WebP for photographic content) are getting in the way, and AVIF handles that job better.
Good to know
- Output characteristics follow AVIF: excellent compression at high visual quality.
- Source quirks still apply — PNG is limited by larger files than JPG or WebP for photographic content, and conversion cannot invent missing data.
- If you care about crisp UI text, prefer lossless destinations or higher quality settings.
- Browser limit: about 40 MB per image, up to 20 files per batch. Very large dimensions are scaled down automatically.
- Need a bigger file? For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.
File size limits for PNG to AVIF
Browser limit: about 40 MB per image, up to 20 files per batch. Very large dimensions are scaled down automatically.
Why there is a limit
Images are decoded into memory on your device. Huge files can freeze or crash the tab, so we cap size to keep conversions reliable without uploading anything.
If your file is too large
For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.
PNG to AVIF FAQ
Common questions about converting PNG files to AVIF.
Is this PNG to AVIF converter free?
Yes. Browser Convert does not charge for PNG → AVIF, add watermarks, or require an account.
Will PNG to AVIF keep image quality?
AVIF may use lossy compression, so pick a higher quality setting when edges and text matter. PNG sources that were already heavily compressed cannot regain lost detail.
Does AVIF support transparency from PNG?
AVIF does not keep an alpha channel the way PNG does. Transparent regions are flattened during conversion.
Is PNG to AVIF conversion private on Browser Convert?
Yes. Your PNG image is processed in the browser. We do not upload the file to convert it, which is the main difference from typical online converters.
Are there file size limits for PNG to AVIF?
Yes. Browser Convert accepts about 40 MB per file, with up to 20 files queued at once. Images are decoded into memory on your device. Huge files can freeze or crash the tab, so we cap size to keep conversions reliable without uploading anything. Very high-resolution images may be downscaled (about 40 megapixels / 8192px on the longest edge) so canvas encoding stays stable. If your file is larger, For larger images, use a desktop editor (GIMP, Affinity, Photoshop) or ImageMagick, then bring a smaller export back here if you still want a quick format change.
Can I convert several PNG files to AVIF at once?
Yes. Queue up to 20 PNG files and convert them in one pass. When finished, download the batch as a ZIP. Very large batches may need to be split so your browser stays responsive.
