AVIF Converter
Upload your AVIF file below and choose the output format. The URL updates instantly as you select, and conversion happens right in your browser — your files stay private.
AVIF (AV1 Image File Format) is the current leader in image compression efficiency. It achieves 20 to 30% better compression than WebP at similar visual quality, and 40 to 50% better than JPG. It supports transparency, HDR color, wide color gamut, and both lossy and lossless compression modes.
The format was developed by the Alliance for Open Media and is based on the AV1 video codec. Browser support has grown quickly: Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+ all support AVIF. Global browser coverage is around 90% as of 2025.
The main trade-off is encoding speed. AVIF takes significantly longer to encode than WebP or JPG, especially when running in a browser via WebAssembly. A 2MB image can take 5 to 20 seconds to encode depending on your device. Decoding is fast, so loading AVIF on a webpage is not slow — only the conversion step takes extra time.
The other reason to convert away from AVIF is software compatibility. Most image editors, CMS platforms, and design tools don't fully support AVIF yet. Converting AVIF to JPG or PNG makes the file usable in any workflow.

When to Use the AVIF Converter
- Optimizing hero images or large graphics on high-traffic web pages where every KB matters
- Replacing WebP for even better compression on platforms that support AVIF natively
- Converting AVIF photos from Android phones to JPG for universal compatibility
- Converting AVIF to PNG for editing in design software that doesn't support AVIF
- Reducing CDN and bandwidth costs on image-heavy websites or apps
- Targeting Chrome 85+, Firefox 93+, Safari 16+ users with the smallest possible files
Real World Examples
Converting hero images to AVIF for a landing page
A landing page has a hero image at 280KB as WebP. Converting to AVIF at 75% quality reduces it to 185KB — a further 34% reduction. For a page with 50,000 monthly visitors, this cuts roughly 4.7GB of monthly image transfer. LCP time on mobile drops from 2.4 seconds to 1.8 seconds on a typical 4G connection.
Converting AVIF phone photos to JPG for a government portal
Some Android phones running Android 12+ save photos as AVIF by default. A user needs to upload a photo ID to a government portal that only accepts JPG. Converting AVIF to JPG at 90% quality takes under 3 seconds in the browser and produces a standard file any portal accepts.
Building a photo portfolio with AVIF for bandwidth savings
A photographer hosts a portfolio of 200 high-resolution photos. Each averages 400KB as JPG. Converting to AVIF at 80% quality brings the average to under 200KB with no visible quality difference at typical monitor sizes. Total image payload drops from 80MB to under 40MB, cutting hosting bandwidth costs roughly in half.

AVIF vs Other Formats
| Format | File Size | Transparency | Best For |
|---|---|---|---|
| AVIF | Smallest available | Yes (HDR + wide gamut) | High-traffic web, max compression |
| WebP | Very small | Yes | Web images, faster encoding |
| JPG | Small | No | Universal compatibility, email, print |
| PNG | Large | Yes | Lossless quality, logos, icons |
Tips for Best Results
- AVIF encoding is slow in the browser — a single 2MB image can take 10 to 20 seconds. Keep the browser tab active during conversion.
- For static assets on high-traffic pages, AVIF compression savings compound quickly. A 30% reduction across 100 images saves real CDN costs.
- Image editors like Photoshop require a plugin for AVIF. Lightroom and GIMP support it natively in recent versions. Convert to PNG first if your editor doesn't.
- Test AVIF output in your target browsers before deploying. Safari 16+ supports it; Safari 15 and earlier do not.
- Pair AVIF with a WebP fallback using the HTML picture element. This covers both AVIF-capable browsers and older ones that only support WebP.
- AVIF at quality 60 to 75 usually looks excellent for photos. Going lower saves more space but introduces visible artifacts on gradients and fine detail.

Frequently Asked Questions
Is the AVIF converter free?
Yes. The tool is completely free to use and doesn't require an account.
Are my files kept private?
Your files are processed locally in your browser and are never sent to our servers. Nothing is stored.
What file size can I upload?
You can upload files up to 50MB. For best performance, files under 10MB process fastest.
Which formats can I convert AVIF to?
You can convert AVIF to PNG, JPG, WebP.
Is AVIF supported in all browsers?
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Global browser coverage is around 90%. For full coverage, pair AVIF with a WebP or JPG fallback in the HTML picture element.
Why does AVIF take so long to encode?
AVIF uses the AV1 codec, which is computationally intensive. Running it in a browser via WebAssembly is slower than native desktop software. A 2MB image may take 5 to 20 seconds depending on your device. Decoding (loading the image in a browser) is fast — only the conversion step is slow.
Should I use AVIF or WebP for my website?
AVIF gives better compression, but WebP is faster to encode and has near-universal browser support. For most sites, WebP is the practical default. Use AVIF for your most important high-traffic pages where the extra compression payoff justifies the slower encoding workflow.
Conclusion
AVIF offers the best compression of any widely-supported image format today. For high-traffic pages, converting hero images and key graphics to AVIF cuts bandwidth and improves load times. Converting AVIF back to JPG or PNG takes seconds when you need broader software compatibility. Upload your file using the tool above and download in seconds — all processing runs in your browser.
