How to use Compress Image
- Choose or drop one or more images.
- Pick the output format and a quality, or enter a target size in KB.
- Click “Compress”.

Supported formats

|---|---|
| Output | JPG, WebP, PNG |
| Processing | On your device, in the browser (no upload) |
Limitations to know
- Compression uses your browser’s encoders; PNG output is lossless, so it shrinks less than JPG or WebP.
- Photo metadata (EXIF, including GPS location) is removed in the output – usually a privacy benefit.
- A target size may be impossible for very large images; the tool then reports the smallest it could reach.
Privacy: Compress Image runs entirely in your web browser. Your JPG/PNG/WebP data is not uploaded, stored or shared, and nothing about its contents is sent to analytics.
Frequently asked questions
How do I compress an image without losing too much quality?
Use JPG or WebP at 70–85% quality – most people cannot see the difference, and files are often 50–80% smaller. Reducing very large dimensions with Resize Image also helps a lot.
How do I get a photo under 100 KB or 200 KB?
Enable “Target size”, enter the limit, and the tool searches for the highest quality that stays under it. If needed, it also suggests resizing.
Are my images uploaded?
No. Images are decoded and re-encoded on your device with the browser’s canvas engine.
