Convert JPEG to AVIF
Get a much smaller AVIF from your JPEG image
How it works
-
Upload your JPEG
Select or drag a JPEG image up to 50 MB.
-
Choose quality
Adjust the AVIF quality slider. AVIF produces much smaller files than JPEG at the same visual quality.
-
Download your AVIF
Get your converted AVIF image instantly.
Why convert JPEG to AVIF?
- AVIF files are 50% smaller than JPEG at the same quality
- Faster loading for websites and web applications
- Supported by all modern browsers (Chrome, Firefox, Safari, Edge)
- Better color accuracy than WebP for photos with subtle gradients and skin tones
- HDR and wide color gamut support (10-bit and 12-bit depth)
- Supported by WordPress (since 6.5), Cloudflare, and all major CDNs
About JPEG to AVIF conversion
AVIF (AV1 Image File Format) is the newest image format, offering the best compression of any widely-supported format. AVIF files are typically 50% smaller than JPEG while maintaining the same visual quality. This makes AVIF ideal for websites where loading speed matters.
AVIF is built on the AV1 video codec, developed by the Alliance for Open Media (Google, Apple, Mozilla, Netflix, and others). It uses perceptual optimization — the encoder concentrates bits where your eyes actually look and saves bits where they won't notice. It also supports film grain synthesis, which means it can strip grain during encoding and re-add it during decoding, saving significant file size on noisy photos.
Real-world adoption is accelerating. Shopify auto-converts product images to AVIF. Squarespace and WordPress (since version 6.5) support AVIF uploads natively. Cloudflare, Fastly, and AWS CloudFront can serve AVIF automatically to supported browsers. If you're building anything for the web in 2026, AVIF should be your default image format.
When to convert JPEG to AVIF
You're optimizing images for a website or web app and want the smallest possible file sizes. AVIF offers better compression than both WebP and JPEG.
This tool converts your JPEG to AVIF at the quality level you choose. Quality 80 is a good starting point — it produces files much smaller than the original JPEG with minimal visible difference.
Note that AVIF encoding is slower than other formats, but the resulting files are smaller. All modern browsers support AVIF.
For content-heavy sites — blogs, e-commerce, portfolios — switching from JPEG to AVIF can cut image bandwidth by 40-60%. That means faster page loads, lower hosting costs, and better Core Web Vitals scores. A 200KB JPEG product photo typically becomes 80-100KB as AVIF with no visible quality loss.
When NOT to use AVIF: if you need universal compatibility with very old browsers (IE11, pre-2022 Safari), stick with JPEG or WebP. For print workflows, AVIF isn't the right choice — use TIFF or PNG instead. And if your images are mostly simple graphics or line art, PNG or SVG will serve you better.
Frequently asked questions
- How much smaller will my AVIF file be?
- Typically 40-60% smaller than the original JPEG at equivalent visual quality. The exact reduction depends on image content.
- Is AVIF supported by all browsers?
- All modern browsers support AVIF: Chrome, Firefox, Safari (since 2022), Edge, and Opera. Only Internet Explorer lacks support.
- Why is conversion slow?
- AVIF encoding is computationally intensive because it uses advanced compression algorithms. The tradeoff is much smaller files.
- What quality setting should I use?
- For web images: 70-80. For high quality: 85-90. AVIF at 70 often looks as good as JPEG at 85 in a much smaller file.
- Is my file stored on your servers?
- Files are kept only long enough for you to download the result. Everything is automatically deleted within 24 hours.
- Does AVIF support transparency?
- Yes. AVIF supports a full alpha channel, similar to PNG and WebP. If you're converting from JPEG (which doesn't have transparency), this won't apply — but if you start from PNG, AVIF preserves the transparent areas.
- Can I use AVIF on WordPress?
- Yes. WordPress has supported AVIF uploads natively since version 6.5 (released March 2024). Older versions need a plugin like ShortPixel or Imagify to handle AVIF. Most managed WordPress hosts (Kinsta, WP Engine, Cloudways) also support AVIF through their CDN integration.
- JPEG vs AVIF vs WebP — which should I use?
- For the smallest file sizes: AVIF wins. It's 20-30% smaller than WebP and 50% smaller than JPEG at equivalent quality. WebP is a good middle ground — smaller than JPEG, broader browser support than AVIF had before 2022. JPEG is the safe fallback that works everywhere, including email clients and very old software.
