What is image compression?
Image compression reduces file size by removing unnecessary data. WebP and JPEG trade a small amount of detail for much smaller files, while PNG preserves every pixel. Everything here is processed locally in your browser.
How to use it
- Choose an output format, quality, and optional maximum width.
- Add one or more images, then compress the queue.
- Change the settings and recompress any image without uploading it again.
Frequently asked questions
Are my images uploaded?
No. The original files and compressed versions stay in this browser tab.
What quality should I use?
For web photos, 70–80% WebP or JPEG is usually a good balance. Use PNG for graphics that need lossless detail or transparency.
Why can PNG become larger?
The browser re-encodes the image and its PNG encoder may differ from the original one. Try WebP or JPEG when file size matters most.
