How to Convert AVIF Images

Follow these simple steps to convert your AVIF images to other formats

1

Upload Files

Drag one or more .avif files onto the upload area, or click to browse your computer. Supported input is AVIF only; other formats should use a different tool.

2

Choose Format

Pick JPG for maximum compatibility, PNG for lossless or transparent graphics, or WebP for modern web projects. You can change format before starting conversion.

3

Adjust Quality

For JPG and WebP, move the quality slider to balance file size and visual fidelity. Higher values preserve more detail; lower values shrink files.

4

Download

Download each converted file individually or use batch download when available. Files remain on your device unless you choose to upload them elsewhere.

AVIF (AV1 Image File Format) refers to an image container format based on the AV1 video codec, standardized by the Alliance for Open Media for efficient, high-quality still images.

Output formats explained

Choose the format that matches how you will use the image. All options below are available from the converter above.

AVIF to JPG

JPG (JPEG) is the most compatible format for photos, social media, email attachments, and older desktop software. Converting AVIF to JPG is ideal when recipients cannot open .avif files or when a website only accepts JPEG uploads. You can tune compression with the quality slider.

AVIF to PNG

PNG supports lossless compression and transparency, which makes it suitable for screenshots, logos, UI assets, and images with sharp edges. File sizes are usually larger than JPG or WebP, but compatibility is excellent across editors and operating systems.

AVIF to WebP

WebP balances size and quality for modern websites and supports transparency in many cases. Converting AVIF to WebP helps when you need broader browser support than AVIF alone while keeping relatively small files for web delivery.

Who uses AVIF.best?

  • Content creators and bloggers who download AVIF images from the web and need JPG or PNG for WordPress, newsletters, or print.
  • Developers and QA testers normalizing user-uploaded AVIF samples to PNG for documentation or bug reports.
  • Everyday users opening photos from newer phones or messaging apps that saved pictures as .avif on disk.

Sources and standards

Major claims about AVIF on this site align with open specifications and industry references:

AVIF is specified as an image format derived from the AV1 bitstream, intended to deliver high compression efficiency for photographic and graphical content.

How AVIF.best works

Processing uses client-side WebAssembly (libavif) inside a Web Worker so the page stays responsive. Files are not uploaded to our servers. We do not publish third-party benchmark scores; conversion speed and output size depend on your device, browser, and source file. Typical runs complete in seconds for common photo sizes on modern desktops.

Frequently Asked Questions

What is AVIF.best?
AVIF.best is a free browser-based AVIF converter operated on avif.best. You can convert AVIF files to JPG, PNG, or WebP without installing desktop software or creating an account. The tool is designed for quick one-off conversions and small batches when you receive .avif images from websites, phones, or creative apps that you need to open elsewhere.
Is AVIF.best safe for private photos?
Yes. Conversion runs locally in your browser using WebAssembly (libavif) inside a Web Worker. Your images are not uploaded to AVIF.best servers for processing. We do not require login for basic conversion. For privacy details, see our Privacy Policy page.
Which formats can I convert to?
From the home converter you can export JPG (with an adjustable quality slider), PNG (lossless-style output suitable for graphics), or WebP (modern web format). Dedicated pages explain AVIF to JPG, AVIF to PNG, and AVIF to WebP workflows with format-specific tips.
Why convert AVIF to JPG or PNG?
AVIF often produces smaller files than JPEG or PNG at similar visual quality, but not every app, email client, or CMS accepts .avif yet. Converting to JPG or PNG helps when you share files with people on older software, upload to platforms that only allow JPEG, or archive images in a universally recognized format.
Can I convert multiple AVIF files at once?
Yes. You can add several AVIF files to the queue and convert them in one session. Batch conversion still runs locally in your browser. Total time depends on file size, output format, and your device CPU. Very large batches may be slower on low-end hardware.
Does AVIF.best work on mobile browsers?
Modern mobile browsers such as Chrome and Firefox for Android generally support AVIF decoding and our client-side converter. Safari on iOS has improved AVIF support over time; if preview fails, try converting to JPG first, then open the JPG in your gallery or editor.
Will converting AVIF to JPG reduce quality?
JPG is a lossy format, so some detail may be lost compared with the original AVIF, especially at low quality settings. Use a higher quality value (for example 85–95) when you need photos to stay sharp. For graphics with text or transparency, PNG is often a better export choice.
Is registration or payment required?
No. AVIF.best is free to use for converting AVIF images to JPG, PNG, or WebP. We do not charge for standard browser-based conversion. If we introduce optional paid features in the future, the core converter will remain clearly labeled.
