PRACTICAL GUIDE
How to compress an image below 500KB
A 500KB target is common when an upload needs both a smaller file and usable image quality. It can be a safer starting point than 100KB for document photos.
Step-by-step
- Add JPG, PNG, or WebP photos to Image Compressor.
- Choose a 500KB target and start compression.
- Zoom in on the result to check faces, logos, and small text.
Check before using the result
Check whether the destination also limits pixel dimensions. File size and image width or height are separate requirements.

A safe way to meet a 500KB limit
A 500KB result depends heavily on pixel dimensions, quality, and scene detail. Start with a target slightly below 500KB. If it looks too soft, resize the image first and compress it again.
- For document photos, zoom in on small text.
- For portraits, check face edges and the area around the eyes.
- For a transparent PNG logo, keep PNG instead of switching to JPG.
