AVIF to JPG, JPG to AVIF - Convert Any Way You Need
AVIF is the next-generation image format developed by the Alliance for Open Media - backed by Netflix, Google, and Apple. It delivers files 25–45% smaller than JPEG and 10–20% smaller than WebP at equivalent visual quality. But not every app, CMS, or email client accepts AVIF yet. This tool converts AVIF to JPG, AVIF to PNG, JPG to AVIF, PNG to AVIF, and WebP to AVIF - all in the browser, completely free.
How to Convert AVIF to JPG - 3 Steps
Step 1: Upload Your Image
Drag and drop an AVIF, JPG, PNG, or WebP file into the upload area, or click "Select Image" to browse. A thumbnail preview appears immediately so you can confirm you've selected the right file.
Step 2: Choose Output Format and Quality
The tool automatically suggests the most useful conversion based on your input - AVIF input defaults to JPG output, while JPG, PNG, or WebP input defaults to AVIF. Override with a single click. Use the quality slider to balance file size and image sharpness. For AVIF output, 75–85% is the sweet spot: dramatically smaller files with imperceptible quality loss. PNG output is always lossless and needs no quality setting.
Step 3: Convert and Download
Click "Convert Image." The result shows original vs. converted file size instantly. Click "Download" to save the file to your device.
What Is AVIF?
AVIF (AV1 Image File Format) is an open, royalty-free image format created by the Alliance for Open Media - a consortium backed by Google, Apple, Netflix, and Amazon. Released in 2019, it uses the same intra-frame compression as the AV1 video codec to achieve file sizes dramatically smaller than JPEG or WebP at equivalent visual quality. AVIF supports HDR colour, wide colour gamuts, transparency (alpha channel), and lossless compression.
As of 2026, AVIF is the preferred format for web images - supported natively by Chrome 85+, Firefox 93+, and Safari 16+. If you need maximum compatibility with older apps, email clients, or CMS platforms, converting AVIF to JPG or PNG remains the fastest solution. Need to shrink files further before converting? Try our Image Compressor first.
AVIF vs WebP vs JPG vs PNG - Which Format Should You Use?
| Format | Best For | Browser Support | File Size vs JPEG |
|---|---|---|---|
| AVIF | Web images, HDR photos, modern apps | Chrome 85+, Firefox 93+, Safari 16+ | 25–45% smaller |
| WebP | Web images needing wide compatibility | All modern browsers | 25–35% smaller |
| JPG / JPEG | Photos, email, universal compatibility | Every device & app | Baseline |
| PNG | Logos, icons, screenshots, transparency | Every device & app | Larger (lossless) |
Frequently Asked Questions
Does converting AVIF to JPG (JPEG) lose quality?
At quality 90–100%, the visual difference is imperceptible for most images. The tool decodes the AVIF with full fidelity using your browser's native renderer, then re-encodes to JPG / JPEG at your chosen quality. Set quality to 95–100 if you need near-lossless output.
What happens to AVIF transparency when I convert to JPG?
JPG does not support transparency. The tool fills transparent pixels with a white background before encoding - the same approach used by professional image editors. If you need to preserve transparency, convert to PNG or WebP instead.
Which browsers support AVIF?
All modern browsers support displaying AVIF images: Chrome 85+, Firefox 93+, and Safari 16+. Encoding AVIF via the browser's Canvas API (which this tool uses) requires a slightly newer version: Chrome 113+, Firefox 113+, or Safari 17+. If your browser is older, you can still convert AVIF to JPG, PNG, or WebP - you just can't encode to AVIF.
Is my image uploaded to a server?
No. All conversion happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device and is never stored anywhere - completely private and secure.
Why is AVIF so much smaller than JPEG?
AVIF uses the AV1 video codec's intra-frame encoding, which is far more sophisticated than JPEG's 30-year-old DCT compression. AV1 uses larger transform blocks, better entropy coding, and a more accurate perceptual model - resulting in dramatically fewer bytes for the same apparent quality.
What quality setting should I use for AVIF output?
75–85% is the sweet spot for most web images - files are dramatically smaller than JPEG at equivalent visual quality. For product photos or hero images where sharpness matters, use 85–90%. For thumbnails and previews, 65–75% produces excellent results. AVIF encodes more efficiently than JPEG, so the quality scale behaves differently - a quality 80 AVIF often looks better than a quality 80 JPEG.
Is AVIF better than WebP?
For pure compression, yes - AVIF typically produces files 10–20% smaller than WebP at equal visual quality, and it handles HDR and wide colour gamuts that WebP cannot. WebP still wins on tooling compatibility: older image editors, CMS plugins, and CDN pipelines are more likely to have native WebP support. For new web projects targeting modern browsers, AVIF is the better choice. For maximum compatibility today, WebP remains a solid fallback.
How do I open an AVIF file on Windows or Mac?
The easiest way is to open the AVIF file in a modern web browser - drag it into Chrome, Edge, Firefox, or Safari and it will display immediately. On Windows 11, the built-in Photos app supports AVIF natively. On macOS 13+, Preview opens AVIF files. For older systems, free tools like XnView MP or IrfanView (Windows) handle AVIF. If you need to use the image in software that doesn't support AVIF yet, use this converter to turn it into a JPG or PNG first.
Can I convert multiple AVIF files at once?
This tool converts one image at a time - upload, convert, download, then repeat for the next file. Each conversion takes only a few seconds, so working through a small batch is quick. If you routinely need to convert dozens of files, a command-line tool like ImageMagick or FFmpeg with AVIF support will handle batch jobs more efficiently.
