JPG to AVIF Converter

What is a JPG File?

JPG (JPEG - Joint Photographic Experts Group) is one of the most widely used image formats for photos and web graphics. It uses lossy compression to reduce file size while keeping acceptable image quality. JPG files are supported by almost all devices, browsers, and editing tools, which makes them ideal for everyday image use. However, newer formats like AVIF offer better compression and improved image quality.

What is an AVIF File?

AVIF (AV1 Image File Format) is a modern image format designed to deliver high-quality images with much smaller file sizes. It uses advanced compression from the AV1 codec, allowing images to maintain excellent visual detail. AVIF also supports features like HDR, transparency, and wider color ranges, making it a powerful format for modern websites and applications. This is why many users choose to convert JPG to AVIF for better web performance.

How to Use the JPG to AVIF Converter?

Converting a JPG takes just a few steps with TestMu AI's free online converter. Everything happens on your own device - the image is never uploaded.

• Open the Converter: Navigate to this page in your web browser. No software installation or registration is required.
• Upload Your JPG: Click the upload area and pick a .jpg or .jpeg file from your computer. The tool works on one image at a time.
• Set Image Quality: Enter a quality value from 1 to 100. Higher settings preserve more detail but produce larger files; 75 is a good starting point.
• Choose Fit Type: Select Max (fits inside your dimensions without enlarging), Crop (fills the exact dimensions and trims the excess), or Scale (stretches to the exact dimensions).
• Enable Auto Orient: Tick this option to apply the EXIF orientation flag so photos taken sideways come out the right way up.
• Convert and Download: Click "Convert". The tool checks whether your browser can encode AVIF; if it cannot, it produces a WebP file instead and says so above the result. Download the output with the button next to the preview.

Key Features of the JPG to AVIF Converter

These features make image conversion simple, private, and predictable for users of all skill levels.

• Honest Format Detection: Before encoding, the tool probes whether your browser has a real AVIF encoder and checks the MIME type of what comes back. If AVIF is not available it produces WebP and tells you, instead of renaming a PNG to .avif.
• Instant Browser Conversion: Images are converted directly in your browser without being uploaded to any server, which means faster processing and complete privacy.
• Quality Control Settings: Set a quality value from 1 to 100 to find the balance you want between file size and visual clarity.
• Automatic Metadata Removal: Because the image is re-encoded from raw canvas pixels, EXIF, GPS coordinates, colour profiles and comments are always stripped from the output.
• Smart Resize Options: Set custom dimensions and pick Max, Crop or Scale to optimise the image for web use or a specific display size.
• EXIF Auto-Orientation: Optionally apply the EXIF orientation flag so rotated photos are written out the right way up.
• Local File Processing: All conversions happen locally in your browser, so your images never leave your device.
• No Software Installation: Access the full converter through any modern web browser without downloading programs or plugins.

One limitation worth knowing about: the tool converts a single image per run. There is no batch mode, so large image libraries are better handled with a command-line encoder or a build-time pipeline.
