AVIF to JPG Converter
Convert AVIF images into JPGs that open in every browser, editor, and device — no more 'unsupported image format' errors.
What Is AVIF?
AVIF (AV1 Image File Format) is a modern image format built on the AV1 video codec, developed by the Alliance for Open Media (AOMedia) — the same group behind Netflix, Google, and Amazon's video compression work. It delivers roughly 50% smaller files than JPEG at comparable visual quality, and supports features JPEG never could: transparency, HDR, wide color gamut, and up to 12-bit color depth.
Browser support for AVIF is now strong — over 93% of browsers in use today can display it, and it's built into every major engine (Chrome, Firefox, Edge, Safari 16.4+). WordPress added native AVIF support in version 6.5.
Why Convert to JPG?
Despite that browser support, AVIF adoption across the wider web is still under 1% of sites. Plenty of software still doesn't handle it: some photo editors, older CMS platforms, certain printing services, and a fair amount of legacy business software either reject AVIF uploads outright or fail to open the file at all.
JPG, on the other hand, works everywhere it has for decades — every device, editor, printer, and platform accepts it without a second thought.
How This Tool Works
This converter runs entirely in your browser using a real libavif decoder compiled to WebAssembly — the same underlying decode technology browsers use natively. Your AVIF file is decoded and re-encoded as a JPG entirely on your device; it's never uploaded to any server. Larger or higher-resolution images take a little longer to process since AVIF decoding is more computationally intensive than older formats.
AVIF vs JPG — When to Use Each
| Feature | AVIF | JPG |
|---|---|---|
| File size | Smaller (roughly 50% of JPEG at similar quality) | Larger |
| Image quality | Excellent, especially at low bitrates | Good, but blocky artifacts at high compression |
| Transparency | Supported | Not supported |
| HDR / wide color | Supported | Not supported |
| Color depth | Up to 12-bit | 8-bit |
| Compatibility | ~93% of browsers, ~1% of websites actually use it | Universal — every device, browser, and editor |
| Editing software | Limited support, growing | Universal |
| Printing services | Rarely accepted | Accepted everywhere |
Keep AVIF When
- Serving images on your own website to modern browsers
- You control both the encoder and the viewing environment
- File size and load time matter more than maximum compatibility
- You need HDR or wide-color-gamut image data preserved
Convert to JPG When
- Uploading to a photo editor, CMS, or platform that doesn't accept AVIF
- Sending images to a printing service
- Sharing with someone whose device or software may not open AVIF
- Archiving photos somewhere long-term compatibility matters more than file size
Common Scenarios for AVIF to JPG Conversion
Uploading to Older Software or Platforms
Many photo editors, e-commerce listing tools, and content management systems still don't accept AVIF uploads. Converting to JPG first avoids a confusing "unsupported file type" error.
Printing Photos
Online and in-store photo printing services almost universally expect JPG. If you've downloaded or been sent AVIF images, converting them first ensures your print order actually goes through.
Sharing with Older Devices
Not everyone's phone, tablet, or desktop software can open an AVIF file, especially on older operating systems. JPG guarantees the recipient can view the image without hunting for the right app.
Archiving Converted Photos
If you're batch-converting a set of AVIF photos and want to keep them as a single, easy-to-browse file, combine the resulting JPGs into one document with Image to PDF afterward.
Editing in Software Without AVIF Support
Some image editors — particularly older versions or budget tools — either can't open AVIF at all or only support a limited subset of it. Converting to JPG first sidesteps compatibility issues entirely.
Email Attachments
Some email clients and corporate mail filters flag or strip unfamiliar attachment types. JPG is universally recognized and rarely causes delivery issues.
Other Ways to Convert AVIF to JPG
You can also convert AVIF to JPG using your device's built-in photo viewer (File → Export or Save As), or an image editor like GIMP or Photoshop. FileCast is useful when you want a quick conversion without opening a separate app.
Frequently Asked Questions
Is it safe to convert my photos here?
Yes. This tool decodes and re-encodes your AVIF file entirely in your browser, using a WebAssembly build of the same libavif decoder browsers use natively. Your image is never uploaded to a server — when you close the tab, all data is gone.
Does converting to JPG reduce image quality?
Slightly. JPG is a lossy format, so there's a small quality reduction during re-encoding. This tool uses a 92% quality setting, which produces JPG files that are visually indistinguishable from the original in normal viewing.
What happens to transparency in my AVIF image?
JPG doesn't support transparency. If your AVIF image has transparent areas, they'll be filled with a white background in the converted JPG. If you need to keep transparency, use AVIF to PNG instead.
Will the file size increase after conversion?
Usually, yes. AVIF is significantly more efficient than JPEG, so converting typically increases file size — often by a large margin for the same visual quality. This is expected; you're trading AVIF's compression efficiency for JPG's universal compatibility.
Why does conversion take a moment for some files?
AVIF decoding is more computationally intensive than older formats like JPEG. Larger or higher-resolution images take longer to process. Everything still happens on your device — there's no upload involved, just more work for your browser to do.
