Why Your Device or App Cannot Open AVIF Files
AVIF is a relatively young format. The specification was finalized in 2019, and while browser support accelerated quickly — Chrome added it in version 85 (August 2020), Firefox in version 93 (October 2021) — the rest of the software ecosystem moves slower.
Here is where AVIF support is still missing or partial:
Adobe Photoshop — AVIF support arrived in version 23.1 (February 2022). Anyone using an older version cannot open these files without a plugin.
Windows Photo Viewer — requires the AV1 Video Extension from the Microsoft Store, which many users never install.
WhatsApp, Telegram desktop, older iOS versions — inconsistent handling of AVIF images in chat contexts.
Email clients (Outlook, Apple Mail, Thunderbird) — none embed AVIF in rendered emails. Recipients either see broken images or nothing at all.
CMS platforms — WordPress added AVIF support in version 5.9 (January 2022), but many hosting environments lack the required libavif library.
The pattern is clear: AVIF works well in cutting-edge web contexts, but struggles everywhere else. When you need universal compatibility, JPEG remains the only format that works literally everywhere — every browser ever made, every image editor, every social platform, every email client, every operating system.
Online Conversion vs. Desktop Software: When Each Makes Sense
You have three general options when facing an AVIF file you cannot use:
Option 1: Install a desktop converter. Tools like XnConvert, IrfanView (with plugin), or GIMP can open and re-export AVIF files. This makes sense if you process hundreds of images daily and need batch automation with fine-grained control over color profiles, metadata stripping, and EXIF handling. The downside: installation, configuration, and updates consume time, and these tools have a learning curve.
Option 2: Use a command-line tool. If you are comfortable with terminals, cavif and libheif's heif-convert can handle the conversion. This is fast and scriptable, but irrelevant for most users who simply want to open a single file.
Option 3: Use an online converter. This is the right choice when you need the result immediately, you are on a device where you cannot install software (a work laptop, a borrowed computer, a phone), or the conversion is a one-time need. A well-built online tool handles the codec complexity server-side and gives you a downloadable JPG in seconds.
The trade-off is trust: you are uploading a file to someone else's server. Reputable converters like Pixes.app process files client-side when possible and delete server copies automatically, but you should always check the privacy policy of any conversion tool before uploading sensitive images.
Maintaining Quality During Conversion
A common concern is whether converting from AVIF to JPG degrades the image. The answer depends on two factors: the original AVIF's quality and the JPEG compression level you choose.
AVIF supports both lossy and lossless compression. If your source file was saved losslessly, converting to JPG at quality 95–100 will preserve virtually all visible detail. If the source was already lossy (common for web-optimized images), you are re-compressing an already compressed file — some additional detail loss is inevitable, but at quality 90+ it is typically invisible at normal viewing distances.
There is one technical nuance worth knowing: AVIF supports 10-bit and 12-bit color depth, while standard JPEG is 8-bit. If your AVIF file contains a wide color gamut (BT.2020, HDR content), the conversion to 8-bit JPEG will clip some of those extra colors. For web photos, screenshots, and standard photography this is rarely noticeable. For HDR content intended for professional color grading, consider converting to PNG instead (the AVIF to PNG tool preserves the full color range when the target format supports it).
When JPG Is the Wrong Choice — and What to Use Instead
JPEG is the universal fallback, but it is not always the optimal target format. Depending on your use case, a different conversion may serve you better:
Need transparency? JPEG does not support alpha channels. If your AVIF file has a transparent background (common for product photos and UI assets), convert to PNG instead.
Need a small file for a website? After converting to JPG, running the result through a JPG compressor can shave off another 20–40% of file size without visible quality loss — useful for page speed optimization.
Want to go back to AVIF later? If you only need JPG temporarily for compatibility, keep the original AVIF file. You can also convert your edited JPG back to AVIF when the final destination supports it.
The point is not that JPG is always the answer — it is that JPG is always accepted. When you need a file to work on any platform, any device, any application, JPEG is the only format with truly universal support. That is why converting AVIF to JPG remains the most requested image conversion task related to this newer format.
Como usar esta ferramenta
Navigate to pixes.app/avif-to-jpg in any modern browser. The tool loads instantly without requiring Flash, Java, or browser extensions.
Drag and drop the .avif file onto the upload area, or click the button to browse your device's file system. You can also paste a file from your clipboard using Ctrl+V (or Cmd+V on Mac).
A quality slider lets you control the output compression level. The default setting (92) preserves most visual detail while keeping file size reasonable. Lower values produce smaller files; higher values approach lossless territory.
Click the convert button and download the result. The file appears in your downloads folder as a standard .jpg or .jpeg file that every platform recognizes.
At high quality settings (90+), the visual difference is negligible for standard photos and graphics. You may notice minor differences when zooming in to 200%+ or when working with HDR/wide-gamut content, which loses some color range in the 8-bit JPEG conversion.
Can I convert multiple AVIF files to JPG at once?
Yes. Pixes.app supports batch uploads — drag multiple .avif files onto the conversion area and download them individually or as a ZIP archive.
Why do some websites save images as AVIF instead of JPG?
AVIF files are typically 30–50% smaller than equivalent JPEG files at similar visual quality. Websites use AVIF to reduce bandwidth costs and improve page load times. Chrome, Firefox, and Safari (16+) serve AVIF to supporting browsers while falling back to JPEG or WebP for older ones.
Is it safe to upload personal photos to an online converter?
It depends on the service. Pixes.app processes conversions client-side when the browser supports it, meaning your file may never leave your device. For server-side processing, files are deleted automatically after conversion. Always review the privacy policy of any tool before uploading sensitive images.
