Compress Images Online
Make photos and graphics smaller for email, websites and forms. Choose a quality level and see the new size straight away.
How to use it
- Drop one or more images onto the page, or choose them from your device.
- Move the quality slider. Lower numbers give smaller files. Values between 60 and 80 usually look the same on screen.
- Check the before and after size on each row, then download the file or all files as a ZIP.
About this tool
Large images slow down websites, fill up inboxes and get rejected by upload forms with size limits. Compressing them removes detail the eye rarely notices and can cut the file to a fraction of its size.
Your images never leave your device. The conversion runs inside your browser, so nothing is uploaded to a server and there is nothing to delete afterwards.
JPG and WebP shrink well with the quality slider. PNG is lossless, so it barely changes unless you also reduce the pixel dimensions. For the smallest result from a PNG, switch the output format to WebP.
Frequently asked questions
How much can I reduce an image?
Photos saved as JPG often shrink by 50 to 80 percent at quality 70 with no obvious loss. Screenshots and graphics respond best to WebP.
Is it really private?
Yes. The page does the work with your browser's built-in image tools, and no file is sent to any server.
Why did my PNG get larger?
PNG is lossless. If you keep PNG output and do not resize, the new file can match or exceed the original. Choose WebP or JPG instead.
Is there a size limit?
There is no limit on our side. Very large images depend on your device's memory.
