Convert PNG to AVIF
Convert PNG images to AVIF, the most compact format modern browsers can display, without losing transparency.
Free workspace
Keep repeat file work in motion after the first export.
Start here without an account, then move into retained files, OCR, and starter workflows when the task stops being a one-off.
Instant use
25 browser conversions / day
Retained files
7-day retained files
Secure processing
10 server jobs / month
Document tools
20 OCR pages / month
Conversion surface
Run the file task now.
The converter stays fast and simple. Workspace features only step in when retention, OCR, or repeat work actually adds value.
How it works
A short path from input to finished export.
The flow stays simple so you can get in, finish the job, and move on without extra setup.
Upload PNG Files
Drag and drop your PNG images or click to browse. You can queue several files at once.
Adjust Quality
Use the quality slider to balance file size against fidelity. The default of 75% suits most images.
Download AVIF
Save the converted file right away. Multiple images are bundled into a ZIP for one-click download.
Why FileMorf
A cleaner route for this conversion.
The tool keeps the core job lightweight while still giving you room to grow into retained, higher-value workflows later.
100% Private
All processing happens in your browser. Your files never leave your device.
Best-in-Class Compression
AVIF's AV1-based encoding produces the smallest files of any mainstream image format, with transparency support.
Batch Processing
Convert multiple files at once. Download as a convenient ZIP file.

The important questions, plus the nearby routes users usually need next.
AVIF typically produces the smallest files of any widely supported web format — often well below an equivalent WebP — and it preserves alpha transparency. If you are optimizing Core Web Vitals or serving image-heavy pages, AVIF is the current end of the compression road.
Yes. Both PNG and AVIF store a full alpha channel, and FileMorf preserves it exactly — anti-aliased edges, soft shadows, and semi-transparent pixels all survive the conversion.
AVIF uses lossy compression, so some pixel data is discarded — that is exactly where the size savings come from. At the default quality setting the loss is invisible for most images. Keep the PNG original as your master copy and re-export whenever you need a different balance of size and quality.
Yes — the encoding runs in your browser, and in-browser AVIF encoding is currently available in Chromium-based browsers such as Chrome, Edge, Brave, and Opera. If your browser cannot encode AVIF, FileMorf reports an error instead of silently producing a different format. The finished files display in Chrome, Firefox, Edge, and Safari 16 or later.
Graphics often shrink by 70-90%, photos even more — AVIF's AV1-based compression is the most efficient in mainstream use.
