AVIF to JPG Converter

What Is the AVIF to JPG Converter?

This tool converts an AVIF image to JPG entirely in your browser -- the file is decoded, redrawn onto a canvas, and re-encoded as JPG without ever being uploaded to a server. AVIF (AV1 Image File Format) offers smaller file sizes than JPEG at similar quality, but JPG remains the most universally supported photo format -- accepted by essentially every website, app, printer, and image editor in existence.

How to Use This Tool

Click the upload area and choose an AVIF file. The converted preview appears immediately; click Download to save it as a real .jpg file.

Why Convert AVIF to JPG

The most common reason to convert AVIF to JPG is maximum compatibility -- some platforms (older CMS uploaders, certain marketplaces, some social networks' upload forms) still don't accept AVIF, while JPG is accepted everywhere without exception. This tool flattens onto a white background first, so a transparent source won't turn black.

What Happens to Your Image During Conversion

The tool loads your AVIF file into the browser's own image decoder, paints it onto a canvas that has exactly the same pixel width and height as the source, and then encodes that canvas as a JPG at a fixed quality setting of 0.92 (on a 0 to 1 scale). Nothing is resized or cropped. A 4000 by 3000 pixel AVIF produces a 4000 by 3000 pixel JPG, and the tool shows the dimensions plus the before and after file size so you can confirm this.

Because the canvas is filled with white before your image is drawn, any transparent or semi-transparent regions in the AVIF blend into white in the JPG. This is necessary because JPG has no transparency channel at all. If you need the see-through areas preserved, JPG is the wrong destination format; PNG or WebP would keep them.

A Worked Example

Suppose you save a product photo from a website and it arrives as an AVIF of 380 KB at 2000 by 2000 pixels. You upload it to a marketplace form that rejects AVIF. After converting here, the preview shows 2000 by 2000 pixels and the size badge might read something like 380 KB to 700 KB. That growth is normal and expected: AVIF uses a more efficient compression method than JPG, so the same picture generally needs more bytes as a JPG. The numbers here are hypothetical, and the actual ratio depends on the image content.

If the marketplace also caps uploads at a maximum file size, you may need to reduce the dimensions in an image editor after converting, since this tool always keeps the original pixel dimensions.

Things to Know Before You Convert

• Browser support decides whether the file opens. The tool relies on your browser to read AVIF. Current versions of the major browsers generally do, but an older browser may fail with an error message. In that case, try a newer browser.
• Animated AVIF becomes a still. A canvas captures a single frame, so you should expect a single still image rather than an animation.
• Quality is not adjustable. The 0.92 setting is a high-quality default that keeps files reasonably sized. It is not lossless, so each JPG save loses a little detail. Convert once from your original rather than re-converting a JPG repeatedly.
• Colors can shift slightly. Canvas rendering works in a standard color space, so an image with a wide-gamut or HDR profile may look a touch different afterwards.
• Metadata is not carried over. A canvas re-encode starts from raw pixels, so camera information stored in the source file is not copied into the JPG.
• The download name follows the source. A file called holiday.avif is saved as holiday.jpg.

When JPG Is the Right Choice, and When It Is Not

Choose JPG when the destination only accepts common formats, when you are emailing photos to people with unknown software, or when you are sending pictures to a print shop. Keep the AVIF when you control the website and want the smallest possible page weight, since AVIF's compression advantage is exactly why it exists. For screenshots, logos, or graphics with sharp text edges, JPG can produce faint blocky artifacts around edges, so PNG is usually a cleaner target for those.
