JPG compression guide

Compress JPG to 500KB

Quick answer: Resize first, then lower JPG export quality until the file stays below 500KB. This preserves more detail than reducing quality alone.

Use this workflow for application forms, email attachments, course portals, and upload systems that reject files over 500KB.

All processing runs in your local browser. Your photos are not uploaded to a server.

How to do it

  1. Upload one or more JPG images to the compressor.
  2. Lower export quality while checking the estimated output size.
  3. If the file remains above 500KB, reduce image dimensions first.
  4. Preview text and faces, then download the result or ZIP archive.

Frequently asked questions

Why is my JPG still over 500KB?

The image may have high pixel dimensions. Reduce width and height first, then lower export quality.

Will 500KB compression reduce quality?

Some compression is lossy, but resizing first lets you keep quality higher while reaching the same file size.

Should I use WebP instead?

WebP can be smaller, but JPG is safer when the receiving system does not clearly support WebP.
