Convert PNG to AVIF
AVIF is the smallest widely supported image format, and converting PNGs to it produces the lightest possible page while keeping transparency.
How to convert PNG to AVIF
Drop your PNG files onto the panel above and press Convert. A whole folder at once is fine, and the AVIF files download individually or as a single ZIP.
Quality is the one setting worth a glance, and 85 or above is visually indistinguishable from the original for photographs. Conversion here runs at maximum quality by default, so you only need to touch it if a smaller file matters more than fidelity — and if it does, compressing afterwards gives you finer control.
Nothing is uploaded. The decoders and encoders run as WebAssembly inside this page, which is why there is no file-size limit, no queue, and no copy of your image on anyone's server.
Why convert PNG to AVIF?
AVIF is the smallest widely supported image format, and converting PNGs to it produces the lightest possible page while keeping transparency.
Chrome, Firefox, and Safari 16.4 or newer all display it.
| PNG | AVIF | |
|---|---|---|
| Compression | Lossless | Lossy or lossless |
| Transparency | Yes, full alpha channel | Yes |
| Animation | No (APNG exists but is rarely used) | Yes |
| Support | Universal | Chrome 85+, Firefox 93+, Safari 16.4+ — weaker outside browsers |
| Best for | Logos, icons, screenshots, diagrams, anything needing transparency | Squeezing the last bytes out of images for a modern website |
What AVIF does to file size
Photographic PNGs commonly shrink by 80–90%.
Even against WebP, AVIF is usually meaningfully smaller.
AVIF encoding is slower than other formats — seconds per large image rather than milliseconds — and support outside browsers is still patchy, so keep the PNG as your master.
Frequently asked questions
How do I convert PNG to AVIF?
Drop your PNG files above, choose AVIF as the output, and press Convert. The files are decoded and re-encoded at maximum quality inside your browser, then download individually or as a ZIP — no upload, no account, no watermark.
Does converting PNG to AVIF lose quality?
AVIF is a lossy format, so the image is re-encoded — at maximum quality, where the difference is imperceptible for photographs. AVIF encoding is slower than other formats — seconds per large image rather than milliseconds — and support outside browsers is still patchy, so keep the PNG as your master.
Can I just rename the file to .avif?
No. The extension only labels the file, while the bytes inside follow the structure of a specific format. Renaming produces a file most software refuses to open. A real conversion decodes the image and re-encodes it in the new format, which is what happens here.
