Why convert AVIF to JPG — and what AVIF actually is
Convert AVIF to JPG when you have an AVIF file that won't open in your image viewer, won't attach to an email correctly, or gets rejected by an upload form. AVIF (AV1 Image File Format) is one of the most efficient image formats available — files are typically 50% smaller than JPG at the same visual quality — but its application support outside modern web browsers is still limited. The avif not supported error is common in Windows Photo Viewer, desktop email clients like Outlook, older versions of Photoshop, print services, and many web upload forms. Converting avif to jpg online resolves all of these compatibility issues at once.
What is AVIF exactly? AVIF was developed by the Alliance for Open Media and approved as a standard in 2019. It is based on the AV1 video codec — the same compression technology used by YouTube, Netflix and other major streaming platforms to deliver video at lower bitrates. Applied to still images, AV1 compression achieves remarkable efficiency: at equivalent visual quality, AVIF is about 50% smaller than JPEG and roughly 20% smaller than WebP. For web developers building high-performance sites, AVIF is increasingly attractive. For users who just found an AVIF file they can't open, converting avif to jpg is the fastest solution.
The avif to jpg conversion preserves all visible image content from the AVIF source. JPG output at high quality settings is visually indistinguishable from the AVIF original for most photographic content. The JPG file will be larger than the AVIF original — because JPG is less efficient than AVIF — but the visual quality is maintained. You will not notice a perceptible quality difference in the converted JPG when viewed at normal sizes.
This avif converter runs entirely in your browser. No file is uploaded to any server — your images stay on your device throughout the conversion process. Upload any number of AVIF files, set your preferred output quality, and download JPG files individually or as a ZIP archive. No account required, no file size limit, no daily conversion limit — free for any number of conversions.
Batch conversion of multiple AVIF files is fully supported. If you downloaded a set of website assets or received a folder of AVIF images, upload them all at once and convert in parallel. All files process simultaneously in your browser. Use the "Download All" button to get a ZIP archive of all converted JPG files. The avif to jpg online converter handles any number of files in a single session.
You can also convert AVIF to PNG for lossless output, compress your JPG result if you need a smaller file size, or convert WebP to JPG for similar compatibility fixes.

Click "Convert All" to process all files in parallel in your browser. Each AVIF file is decoded and re-encoded as a standard JPG. The conversion preserves all visible image content from the AVIF source.
- 4Download your JPG files
Each converted file shows the original AVIF size and the output JPG size. Download individually or click "Download All" for a ZIP archive. Your JPG files now open in every app, viewer, and service without any compatibility issues.
Who converts AVIF to JPG — and why
Web developers — downloading website assets that are AVIF
Modern web developers and SEO professionals often download images from websites for reference, competitive research, or asset management. Increasingly, those downloaded images are AVIF files — because the sites serving them are already optimised for next-generation formats. Converting avif to jpg online lets you open, edit, and use those downloaded assets in any standard application. Many image editing tools and design applications do not yet support AVIF natively — JPG is the universally editable intermediate format.
Windows users — fixing AVIF not supported errors
Windows Photo Viewer and older Windows Photos app versions do not support AVIF. When you encounter an AVIF file on Windows, you will typically see a "this file type isn't supported" error or a generic file icon with no preview. Converting avif to jpg free gives you a file that opens in Windows Photos, Windows Explorer thumbnail preview, Paint, and every other Windows application without any codec installation or Microsoft Store purchase. The JPG output is compatible with every version of Windows.
Email users — AVIF attachments that won't display
Most desktop and web email clients — Outlook, Thunderbird, older Gmail in certain browsers — cannot render AVIF images inline in emails. If someone sends you an AVIF image attachment or you are trying to attach AVIF images to an email, the recipient may see a broken image or a download attachment rather than an inline photo. Converting AVIF to JPG before attaching to email ensures the image displays correctly in every email client, on every platform.
Print services — AVIF files rejected by photo labs
Online photo printing services and local photo labs accept JPG and sometimes PNG, but virtually none accept AVIF. If you have downloaded AVIF images you want to print — whether personal photos processed through a web service, or images from a client project — converting AVIF to JPG is required before you can place a print order. The convert avif to jpg free tool produces JPG files suitable for any print service at standard quality settings.
Why use this AVIF to JPG converter
Fix AVIF compatibility — private, fast, and no installation required.
AVIF converted to JPG — opens in every app and device
AVIF is one of the most efficient image formats ever created — but browser and application support is still catching up. Outlook, Windows Photo Viewer, many desktop applications, print services, and email clients simply do not know what to do with an AVIF file. Converting AVIF to JPG gives you a file that opens in every image viewer, every email client, every web application, and every device — without any error messages, codec downloads, or "unsupported format" prompts. JPG has 30+ years of universal support behind it.
Your AVIF files never leave your device
All conversion runs locally in your browser using JavaScript and the Canvas API. No file is uploaded to any server, transmitted over the network or stored anywhere. The tool works without an internet connection after the initial page load. Safe for professional photos, design assets, and any content that cannot touch a third-party server. Your AVIF files stay on your device throughout the entire process.
Convert multiple AVIF files to JPG in one session
Upload as many AVIF files as you need — there is no batch size limit. All files are processed in parallel in your browser. When conversion is complete, download each JPG individually or use the "Download All" button to get a ZIP archive containing every converted file. Convert an entire folder of AVIF images to JPG in a single session without any file size or count restrictions.
AVIF explained — format guide and compatibility reference
What is AVIF — the next-generation image format
AVIF stands for AV1 Image File Format. It is a modern image format developed by the Alliance for Open Media — the same industry consortium (including Google, Netflix, Apple, Mozilla, and Microsoft) that created the AV1 video codec. AVIF uses AV1 compression to achieve remarkable image efficiency: at the same visual quality, AVIF files are typically 50% smaller than JPEG and about 20% smaller than WebP. A 200 KB JPEG image might be 100 KB as AVIF — with no perceptible quality difference. AVIF also supports features well beyond JPEG: full HDR (high dynamic range), wide colour gamut (including Display P3 and Rec. 2020), lossless compression mode, transparency (alpha channel), and both 8-bit and 12-bit colour depth. AVIF was designed to be the universal image format for both web and general use — and it is increasingly used by web developers optimising for performance, and by services like Netflix that need to efficiently deliver billions of images. Understanding what AVIF is explains why you might encounter AVIF files: they come from modern web browsers saving images, web scrapers downloading website assets, or web developers working with next-generation formats.
AVIF support — where it works and where it doesn't
AVIF has good modern browser support: Chrome supports AVIF since version 85 (2020), Firefox since version 93 (2021), and Safari since version 16.4 (2023). This means AVIF images display correctly in all current desktop and mobile browsers. However, AVIF support outside the browser is still limited — and this is the source of the "AVIF not supported" problem most users encounter. Windows Photo Viewer and the older Windows Photos app versions do not support AVIF. Microsoft Paint does not support AVIF. Outlook and most desktop email clients cannot render AVIF images inline. Adobe Photoshop added AVIF support in 2021 but requires the format to be enabled. GIMP has added AVIF support, but older versions do not have it. Apple Preview on macOS supports AVIF since macOS Ventura — older Macs cannot open AVIF. Print services and photo labs almost universally reject AVIF. Many web content management systems, image upload forms, and web services do not accept AVIF. Converting AVIF to JPG is the most reliable way to ensure an AVIF file can be used anywhere, regardless of the receiving application's format support.
How to fix AVIF not supported — convert to JPG
If you encounter an AVIF file you cannot open — whether because your image viewer shows an error, an application rejects it, or an email client cannot display it — converting it to JPG is the universal fix. JPG (JPEG) was standardised in 1992 and is supported by every image viewer, every web browser, every email client, every printer, and every image editing application without exception. To fix the AVIF not supported error: upload the AVIF file to this converter, click "Convert All", and download the JPG output. The resulting JPG opens everywhere with no setup, no codec installation, and no errors. For Windows users specifically: if you want to add AVIF support to Windows rather than convert, you can install the AV1 Video Extension from the Microsoft Store — but this requires Windows 10 version 1903 or later, and it only adds support to Windows Photos, not to other applications. Converting to JPG is a more comprehensive and portable solution.
AVIF vs JPG vs WebP — format comparison
Comparing AVIF, WebP, and JPG in terms of compression efficiency and compatibility reveals a clear trade-off. JPG (JPEG) offers the widest compatibility — universal support across every device, app, and service — but the least efficient compression. A photo at high JPG quality might be 200–300 KB. WebP, developed by Google in 2010, offers 25–35% smaller files than JPG at the same quality, and is now supported by all modern browsers. WebP is the recommended format for web images. AVIF offers 50% smaller files than JPG — and roughly 20% smaller than WebP — at the same visual quality. AVIF is the most efficient of the three for photographic content. However, AVIF has the most limited ecosystem support outside modern browsers. In practice: use JPG for maximum compatibility (email, desktop apps, print, services that do not accept WebP or AVIF); use WebP for web images where you control the serving environment; use AVIF if you are building a high-performance web application and your target browsers all support it, and you have fallbacks for others. When you receive an AVIF file and need to use it in a context that does not support AVIF, converting to JPG is the straightforward compatibility fix.
