Native AVIF decoding
Uses the browser image pipeline with an Image-based fallback when createImageBitmap is unavailable or rejects the file.

How conversion works
From efficient AVIF pixels to widely compatible JPEG
The browser decodes the selected AVIF into pixels, draws those pixels onto an HTML Canvas, and encodes a new JPEG file at your selected quality. This is a real decode-and-encode operation, not a renamed file extension or a copy of incompatible AVIF bytes.
Important output behavior
- Transparent pixels are flattened because JPEG has no alpha channel.
- Animated AVIF exports only its primary or first displayed frame.
- Metadata, gain maps, depth data, and auxiliary images are not copied.
- HDR and wide-gamut colors may be tone-mapped by the browser.
- JPEG output is lossy, even when quality is set to 100.
Purpose-built controls
Everything needed for a dependable conversion
Manage output quality, dimensions, transparency, previews, failures, and downloads without turning the page into a bright generic utility.
Quality control
Choose JPEG quality from 1 to 100 for smaller sharing files or higher-detail photographic results.
Optional resizing
Preserve original dimensions or constrain the longest edge to 4096, 2048, or 1024 pixels without upscaling.
Alpha flattening
Select a white, black, or custom background for transparent and partially transparent AVIF pixels.
Batch safeguards
Sequential processing, file limits, combined-size validation, and pixel limits help prevent unbounded browser memory usage.
Flexible downloads
Inspect and download individual results or package all successful JPG files into one clearly named ZIP archive.
Three-step workflow
Convert without unnecessary complexity
Add AVIF images
Browse, drag, or drop one or more valid AVIF files into the private conversion workspace.
Choose JPG settings
Set quality, longest-edge resizing, and the background used for transparent source pixels.
Preview and download
Review dimensions and file sizes, then download one JPG or all successful results in a ZIP.
Format comparison
AVIF and JPG serve different needs
Conversion improves compatibility, but it cannot carry every AVIF capability into the older JPEG format.
| Capability | AVIF source | JPG output | Conversion result |
|---|---|---|---|
| Photographic compression | Highly efficient | Widely supported | Pixels are re-encoded lossily |
| Transparency | Supported | Not supported | Flattened onto selected color |
| Animation | Possible | Not supported | First or primary frame only |
| HDR and wide gamut | Possible | Viewer dependent | Browser color conversion may occur |
| Source metadata | May be embedded | Can support metadata | Not copied by this Canvas workflow |
| Legacy compatibility | More limited | Excellent | JPG is easier to share broadly |
Best practices
Get cleaner, more predictable JPG files
Start around quality 90
This is a practical starting point for photographs. Compare the preview and file size before choosing a more aggressive setting.
Choose the alpha color deliberately
Logos and cutout images may contain transparency that is difficult to notice until the JPG is displayed on another background.
Resize for the destination
A 1024 or 2048 pixel longest edge is often enough for messaging, previews, listings, and many web interfaces.
Keep the original AVIF
JPG conversion discards AVIF-only capabilities and source metadata. Retain the original if archival fidelity or later editing matters.
Frequently asked questions
AVIF to JPG answers
Is AVIF to JPG conversion private?
Yes. Your AVIF files are decoded and converted locally in your browser. This page does not upload the selected image bytes to a conversion server.
Does JPG preserve AVIF transparency?
No. JPEG does not support an alpha channel, so transparent AVIF pixels are flattened onto the white, black, or custom background you select.
Does conversion preserve AVIF metadata?
No. The browser decodes the visible pixels and creates a new JPEG. EXIF, GPS, XMP, ICC metadata, depth data, gain maps, auxiliary images, and other source metadata are not retained.
What happens to an animated AVIF?
Only the primary or first displayed frame is converted. JPEG is a still-image format, so animation and later frames are not included.
Why can AVIF and JPG colors look different?
HDR or wide-gamut AVIF content may be tone-mapped or color-converted by the browser and Canvas pipeline. JPEG output can therefore look different from the original in some viewers.
Which JPEG quality setting should I use?
A setting near 90 provides a strong balance for most photos. Higher settings can retain more detail but produce larger files, while lower settings reduce size with more visible compression.
Which browsers can convert AVIF?
Current versions of major browsers generally support AVIF. If your browser cannot decode a particular AVIF profile or file, the converter will report that file as unsupported instead of producing a false result.
