Image Compressor
Shrink JPG, PNG and WebP images without uploading them.
About this tool
Make images smaller so websites load faster and files fit email limits. Your image is compressed locally using your browser, so it is never uploaded to a server. Adjust quality, optionally limit the maximum width, and compare the before and after sizes.
How to use it
- Choose an image from your device.
- Set the quality and, if you wish, a maximum width.
- Check the new size, then download the compressed image.
Frequently asked questions
Does compression reduce quality?
Slightly. A quality of 70 to 85 percent typically cuts size substantially with little visible change.
Are my images uploaded?
No. Compression happens entirely in your browser.
Which output format is smallest?
WebP is usually smallest, followed by JPEG. PNG is best for graphics that need transparency.
