Image Compressor
Compress JPG, PNG and WebP images to reduce file size — instantly in your browser, with a quality slider.
Reduce the file size of a JPG, PNG or WebP image without uploading it anywhere. Adjust the quality slider to control the trade-off between file size and visual quality, and see the original size, new size and percentage saved before you download.
How to Use Image Compressor

- Adjust the quality slider to set the compression level.

Tips for Better Results

- Start at 80% quality and lower it gradually while checking the preview
FAQ
Why didn't my PNG get much smaller?
PNG is a lossless format, so the quality slider has limited effect on it. Converting to WebP usually gives a bigger size reduction for PNG images.
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API.
Will compressing reduce the image's dimensions?
No, only the file size and visual quality are affected. Use the Image Resizer to change dimensions.
