Image Compression Guide

Optimize images with practical size and quality tradeoffs.

If privacy matters, this compressor is built around local browser processing. Select your images, choose a target size and output format, then compress them on your device. The selected source files are not sent to an Imglio server for processing.

Why Imglio? Imglio is made for quick, private image compression without a server upload step. It gives you clear file-size presets and local processing, while staying honest about the tradeoff: the final size depends on the image content, dimensions, and chosen format. You can also switch the output to JPG, PNG, or WebP from the settings panel.

How to Use

  1. Upload one or more images, or drag them into the upload box
  2. Choose 500KB in the target size setting
  3. Pick the output format, or leave it on original format
  4. Rotate any image if needed
  5. Click "Compress Now" and download the result when processing is done
