Image Compressor
Make photos and pictures much smaller with no visible difference — for websites, email and more room.
How to compress a picture
- Choose your pictures
JPG, PNG, WebP, HEIC and more — one or hundreds.
- Pick the quality
75% looks the same as the original for nearly every photo. Shrink the size too for even smaller files.
- Compress and compare
Drag the slider to compare before and after, then download one by one or all in a ZIP.
Questions
Is it really free, with no sign-up and no watermark?
Yes, completely. There's no sign-up, no login, no watermark and no daily limit: just open the page and start. It works in your browser on any computer, phone or tablet with nothing to install, and your files are never uploaded — everything happens on your device.
How do I compress a JPG to under 100 KB?
Lower the quality to about 60% and choose "At most 1280 px" (or 800 px for very small files). Each picture shows its new size, so you can adjust and compress again.
How do I make a PNG smaller?
Save it as WebP: it keeps see-through parts and is usually several times smaller. For photos without transparency, JPG works too.
Will my photos lose quality?
At 70–80% the difference is very hard to see. Compare before and after with the slider before you download.
Are my pictures uploaded?
No. They're compressed in your browser, on your device.
