Image Converter Guide

Convert images to supported formats quickly with local browser processing.

Convert JPG images to AVIF format directly in your browser. Imglio lets you process one or more images, rotate them if needed, and download the converted files from the results page. It is useful for website images, sharing, app uploads, and format compatibility.

Why Imglio? Imglio keeps conversion simple: pick files, choose a format, and process locally in your browser. It avoids the upload-wait-download loop that many online converters use. If the output format supports transparency, transparent pixels can be kept by the browser encode step. For the best result, choose the format based on how the image will be used.

How to Use

  1. Upload JPG images
  2. Confirm the input format and choose AVIF
  3. Rotate any image if the orientation is wrong
  4. Click "Convert Now"
  5. Download the converted files from the results page

Frequently Asked Questions

For web use, yes. AVIF consistently produces smaller files than JPG at the same visual quality, often by 40-50%. It also supports transparency and HDR, which JPG doesn't. The tradeoff is that very old browsers don't support AVIF, but all modern browsers do.
JPG to AVIF conversion is best for smaller web files, but it cannot restore detail that was already lost in the JPG. The final look depends on the source image and browser encoding.
Most modern CMS platforms like WordPress (with a plugin), Shopify, and Webflow support AVIF. Check your platform's documentation to confirm before converting your entire image library.
