How to compress an image
- Choose one or more pictures, or drop them on the box.
- Pick JPG or WebP for photos. Lower the quality for a smaller file; 70 to 85 percent usually looks the same on screen.
- Optionally cap the longest side, for example 2000 pixels, which cuts file size a lot for big phone photos.
- Press Compress the pictures. Each result shows the old and new size, and you can download them one by one or as a zip.
Your pictures stay on your device
The compression happens in this page with your browser's own image tools. Nothing is uploaded, so you can compress private photos and documents.
What makes the biggest difference
- Dimensions first. A 4000-pixel phone photo shown at 1200 pixels wastes most of its bytes. Cap the longest side.
- JPG or WebP for photos. PNG is lossless and large; keep it for screenshots, logos and anything with sharp edges or transparency.
- Quality 70 to 85. Below 60 you will usually see blocky edges.
Limits to know
- This re-saves each picture through your browser, which also removes metadata such as camera details and location. That is usually what you want for the web, but keep the original if you need it.
- Compressing an image that is already small and well compressed can make it larger. The result shows the real size so you can skip it.
- Up to 40 pictures and 400 MB at a time.

Frequently asked questions
How do I compress an image for free?

Are my pictures uploaded?
No. The compression happens on your device inside the page.
What quality should I use?
70 to 85 percent usually looks the same as the original on screen and is much smaller.
Does compressing remove the metadata?
Yes. Re-saving through the browser drops camera details and location data from the copy. Your original is untouched.
Why did my file get bigger?
A picture that was already well compressed can grow when saved again, or when converted to PNG. The result shows the real size so you can keep the original.
