AVIF Conversion Guide

AVIF to JPG, JPG to AVIF — Convert Any Way You Need

AVIF is the next-generation image format developed by the Alliance for Open Media — backed by Netflix, Google, and Apple. It delivers files 25–45% smaller than JPEG and 10–20% smaller than WebP at equivalent visual quality. But not every app, CMS, or email client accepts AVIF yet. This tool converts AVIF to JPG, AVIF to PNG, JPG to AVIF, PNG to AVIF, and WebP to AVIF — all in the browser, completely free.

How to Convert AVIF to JPG — 3 Steps

Step 1: Upload Your Image

Drag and drop an AVIF, JPG, PNG, or WebP file into the upload area, or click "Select Image" to browse. A thumbnail preview appears immediately so you can confirm you've selected the right file.

Step 2: Choose Output Format and Quality

The tool automatically suggests the most useful conversion based on your input — AVIF input defaults to JPG output, while JPG, PNG, or WebP input defaults to AVIF. Override with a single click. Use the quality slider to balance file size and image sharpness. For AVIF output, 75–85% is the sweet spot: dramatically smaller files with imperceptible quality loss. PNG output is always lossless and needs no quality setting.

Step 3: Convert and Download

Click "Convert Image." The result shows original vs. converted file size instantly. Click "Download" to save the file to your device.

AVIF vs WebP vs JPG vs PNG — Which Format Should You Use?

  • AVIF: Best compression available today. 25–45% smaller than JPEG, 10–20% smaller than WebP at the same quality. Full transparency and HDR support. Supported by Chrome 85+, Firefox 93+, Safari 16+. Ideal for websites and apps where modern formats are acceptable.
  • WebP: A safe next-gen choice with near- universal browser support. 25–35% smaller than JPEG. Good when you need wide compatibility but want better compression than JPEG.
  • JPG: Universal compatibility — every device, app, and email client accepts it. Best for photos and complex imagery. Does not support transparency.
  • PNG: Lossless quality and full transparency support. Ideal for logos, icons, screenshots, and graphics with sharp edges. Larger file sizes than AVIF, WebP, or JPG for photographs.

Frequently Asked Questions

Does converting AVIF to JPG lose quality?

At quality 90–100%, the visual difference is imperceptible for most images. The tool decodes the AVIF with full fidelity using your browser's native renderer, then re-encodes to JPG at your chosen quality. Set quality to 95–100 if you need near-lossless output.

What happens to AVIF transparency when I convert to JPG?

JPG does not support transparency. The tool fills transparent pixels with a white background before encoding — the same approach used by professional image editors. If you need to preserve transparency, convert to PNG or WebP instead.

Which browsers support AVIF?

All modern browsers support displaying AVIF images: Chrome 85+, Firefox 93+, and Safari 16+. Encoding AVIF via the browser's Canvas API (which this tool uses) requires a slightly newer version: Chrome 113+, Firefox 113+, or Safari 17+. If your browser is older, you can still convert AVIF to JPG, PNG, or WebP — you just can't encode to AVIF.

Is my image uploaded to a server?

No. All conversion happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device and is never stored anywhere — completely private and secure.

Why is AVIF so much smaller than JPEG?

AVIF uses the AV1 video codec's intra-frame encoding, which is far more sophisticated than JPEG's 30-year-old DCT compression. AV1 uses larger transform blocks, better entropy coding, and a more accurate perceptual model — resulting in dramatically fewer bytes for the same apparent quality.

What quality setting should I use for AVIF output?

75–85% is the sweet spot for most web images — files are dramatically smaller than JPEG at equivalent visual quality. For product photos or hero images where sharpness matters, use 85–90%. For thumbnails and previews, 65–75% produces excellent results. AVIF encodes more efficiently than JPEG, so the quality scale behaves differently — a quality 80 AVIF often looks better than a quality 80 JPEG.
