Compress images
Make your photos smaller so they upload faster and fit size limits. The work happens in your browser, so your files stay on your device.
100% private. Your files are processed entirely in your browser and never uploaded.
JPEG cannot store transparency. See-through areas are filled with this colour.
How to compress an image
- Add your images. Drop them on the box or pick them from your device, one or many.
- Set the quality. A lower setting makes a smaller file, a higher one keeps more detail.
- Press Compress. Check the saving on each thumbnail, then download one at a time or all in a zip.
Your files never leave the page. Each image is read and compressed by your own browser, so nothing is uploaded and nothing is stored on a server.
FAQs about Compress images
How much smaller will my image get?
It depends on the photo and the quality you choose. A large photo often drops by half or more. You can see the exact saving next to each result before you download.
Will compressing lower the quality?
JPEG compression drops some fine detail to save space. Near the middle setting most people notice no difference on a normal screen. Go lower only when you need a very small file.
Can it handle many images at once?
Yes. Add as many as you like, compress them together, then download them one by one or as a single zip.
What happens to a PNG with a see-through background?
JPEG cannot store transparency, so any see-through area is filled with a colour you pick, white by default. If you need to keep the transparency, keep the file as a PNG instead.
Are my images uploaded anywhere?
No. They are read and compressed by your own browser. Nothing is sent to a server, so even private photos stay with you.
