What this tool does

Large images slow uploads and may hit platform file size caps — compression reduces bytes with minimal visible loss.

Browser-based compression keeps photos on your device — nothing uploads to a server.

How to use it

  1. 1

    Upload your image file locally.

  2. 2

    Adjust quality slider to balance size vs. visual quality.

  3. 3

    Download the compressed image — ready for Instagram, web, or email.

Quality settings

Start at 80% quality — most social posts look identical. PNG for graphics with text; JPEG for photos.

Compress before watermarking if both tools are in your workflow.

Tips

  • Compare file size before and after — aim for under 1MB for most social posts.
  • Keep an uncompressed master archive separately.

Is compression done on a server?
