AVIF to JPG Converter — Browser-Native, No Server Upload

Convert AVIF images to JPG, PNG or WebP directly in your browser using the native Canvas API. Furthermore, a quality slider controls output compression from 1 to 100 for JPG and WebP outputs. No file is uploaded to any server — conversion happens entirely within your browser session for maximum privacy.

How to use the AVIF to JPG

Drop your AVIF file

Drag an AVIF image onto the drop zone or click to browse. Furthermore, modern browsers including Chrome and Firefox natively decode AVIF images — the Canvas API draws the decoded image to a canvas for re-encoding. The original file size appears in the stats strip.

Choose output format and quality

Select JPG, PNG or WebP as the output format. Furthermore, JPG is the most compatible format and the best choice for sharing with people using older software. Adjust the quality slider — 90% produces near-lossless JPG output. Lower values reduce file size at the cost of visible compression artefacts.

Preview and download

The converted image preview appears instantly below the controls. Furthermore, the stats strip shows the estimated output file size alongside the original AVIF size. Click Download to save the converted image.

AVIF versus JPG versus WebP

AVIF is the newest format with the best compression. Furthermore, JPG has the widest compatibility across all devices and software. WebP sits between the two in both compression efficiency and compatibility.

Format	Compression	Compatibility	Best for
AVIF	Best (smallest files)	Modern browsers only	Web images for Chrome/Firefox users
WebP	Good (25–35% smaller than JPG)	All modern browsers	Web images, social media
JPG	Good (widely tested)	Universal (all software)	Email, print, older software compatibility
PNG	Lossless (larger files)	Universal	Screenshots, graphics, transparency

How browser-native AVIF conversion works

Modern browsers include native AVIF decoders. Furthermore, loading an AVIF into an HTML Image element triggers the browser's built-in decoder. The Canvas API then re-encodes the decoded pixels in the target format.

AVIF → Browser decoder → Canvas pixels → Canvas.toDataURL(format, quality)

Browser support: Chrome 85+, Firefox 93+, Edge 121+, Safari 16+
Quality range: 0.0–1.0 (passed as second parameter to toDataURL)
White fill: applied before drawImage to prevent transparent areas appearing black in JPG

Worked example: converting an AVIF camera export

A photographer's camera saves RAW exports as AVIF but their client's design software only accepts JPG. Using AVIF to JPG:

A 3.2 MB AVIF converts to a 4.1 MB JPG at 90% quality — JPG files are typically larger than AVIF at equivalent visual quality because AVIF's compression is more efficient. Furthermore, the JPG opens in all design applications. Moreover, reducing the quality slider to 80% produces a 2.8 MB JPG — smaller than the original AVIF while remaining visually indistinguishable at normal viewing distance.

What is AVIF?

AVIF (AV1 Image File Format) is a modern image format developed from the AV1 video codec. Furthermore, it achieves significantly better compression than JPG and WebP at equivalent visual quality — typically 50% smaller than JPG and 30% smaller than WebP. AVIF was designed for web image delivery and is optimised for photographs, illustrations and graphics equally. Moreover, while AVIF is increasingly supported across modern browsers, legacy software and older devices do not support it — converting to JPG ensures universal compatibility.

When to convert AVIF to JPG

Converting AVIF to JPG is necessary when sharing images with recipients who use software without AVIF support. Furthermore, email clients, Windows Photo Viewer and many older graphics programs display AVIF files as broken or unsupported. Social media platforms vary in their AVIF support — JPG remains the safest format for cross-platform image sharing. Moreover, some cameras and screen capture tools export AVIF by default, making a conversion tool essential for workflows that must support diverse recipient software environments.

Why browser-native conversion protects privacy

Server-based conversion uploads every image to a third-party service. Furthermore, AVIF files from professional cameras may contain GPS coordinates, personal metadata and sensitive content inappropriate for external server processing. Browser-native conversion using the Canvas API processes images entirely within the device memory. Moreover, the conversion runs at the speed of local processing — no upload or download latency regardless of connection speed.

Frequently asked questions

Does my browser support AVIF?+

Chrome 85 and later, Firefox 93 and later, Edge 121 and later, and Safari 16 and later all support AVIF natively. Furthermore, if the AVIF file loads into the browser's Image element, the conversion will work. If the browser does not support AVIF, the image will not load and the tool will not produce output. Moreover, for unsupported browsers, consider updating to a current browser version before using AVIF conversion tools.

Why is the JPG output larger than the AVIF input?+

AVIF achieves better compression than JPG — this is by design. Furthermore, a 1 MB AVIF image converted to JPG at 90% quality typically produces a 1.2–1.8 MB JPG. The extra size comes from JPG's less efficient compression algorithm, not from added data. Moreover, this size increase is expected and unavoidable when converting from a more efficient format to a less efficient one. The visual quality of the JPG can match the AVIF quality at appropriate quality settings.

Can I convert multiple AVIF files at once?+

The tool currently processes one file per session. Furthermore, drop a new AVIF file to replace the current one and download each conversion separately. For batch conversion of many AVIF files, command-line tools like ImageMagick or FFmpeg handle bulk conversion efficiently. Moreover, a browser-based batch conversion feature is planned for a future version of this tool.

Will metadata be preserved in the converted file?+

AVIF metadata — including EXIF data such as camera settings, GPS coordinates and timestamps — may not transfer to the output JPG through Canvas-based conversion. Furthermore, the Canvas API draws the pixel data without preserving the original file's metadata structure. This is generally beneficial for privacy but may be undesirable for photographers who need to retain copyright and location data. Moreover, use the EXIF Data Viewer to check what metadata is present before deciding whether to preserve or remove it.

What quality setting produces the best result?+

Quality 85–92% produces near-lossless results for most photographs — visually indistinguishable from the source at typical screen viewing distances. Furthermore, quality 75–85% is the standard range for web images — good quality at significantly reduced file sizes. Quality below 70% introduces visible compression artefacts, particularly in areas of fine texture. Moreover, AVIF inputs at high visual quality convert best at 88–95% to avoid adding compression artefacts on top of the source image.
