Tips & Tricks
Next-Gen Compression
AVIF uses the modern AV1 codec and usually produces smaller files than JPEG at similar visual quality. It can carry HDR, a wide colour gamut and transparency. This tool writes lossy AVIF through your browser's encoder, with an adjustable quality setting.
When to Use AVIF
Choose AVIF for cutting-edge web applications where bandwidth savings are critical. It offers the best compression ratio among modern image formats.
AVIF Best Practices
Use AVIF with a WebP or JPEG fallback for broad browser support. It excels at photographs and complex images but may not compress simple graphics as efficiently.
Common Use Cases
Bandwidth Savings
Drastically reduce data transfer costs with superior compression
High-Resolution Images
Serve 4K and 8K photos at a fraction of the original size
HDR Photography
Preserve HDR metadata and wide color gamut information
Streaming Thumbnails
Generate ultra-efficient preview thumbnails for media libraries
Content Delivery
Minimize CDN costs with the smallest possible image files
Progressive Web Apps
Build fast-loading PWAs with minimal image payload
Frequently Asked Questions
Are my images uploaded to a server?
No. All processing runs entirely in your browser via the Canvas API. Your images never leave your device.
Is AVIF widely supported in browsers?
AVIF is supported by Chrome 85+, Firefox 93+, Opera 71+, and Safari 16.5+. Support is growing rapidly. For the best reach, offer WebP or JPEG as fallbacks alongside AVIF using the
Is there a file size limit?
Yes, each file must be under 50 MB. There is no fixed limit on how many files you can add, but very large batches take a while because everything runs in your browser tab.
How does AVIF compare to WebP?
As a format, AVIF usually compresses better than WebP at the same visual quality, and it can carry 10-bit HDR colour and wider gamuts. The trade-off is reach: WebP has been supported for longer, so older browsers and software are more likely to open it. This tool writes lossy AVIF through your browser's encoder.
Can I convert multiple images at once?
Yes. Add as many images as you need — there is no fixed batch limit — then download each file individually or grab them all as a ZIP archive.
Does AVIF support transparency?
Yes. AVIF supports an alpha channel, so logos and graphics with transparency convert cleanly. Unlike JPEG, you do not lose the transparent background when choosing AVIF.
