What is the Image Compressor?
An image compressor reduces how much space a photo takes up without a noticeable drop in quality. Smaller files load faster on websites, fit under upload limits, and are quicker to email or message. This tool lets you choose the quality level and instantly see the new file size against the original, so you can find the sweet spot between size and sharpness. It supports JPG, PNG and WebP and does all the work in your browser, so your pictures are never uploaded.
How to use the Image Compressor
- Drop in an image or click to choose one.

Frequently asked questions
Will compressing ruin the quality?
Not if you keep the quality reasonably high. The slider lets you trade a little sharpness for a much smaller file, and you can preview the result.
Which formats can I compress?
JPG, PNG and WebP. You can also change the output format while compressing.
Are my photos uploaded?
No. Compression happens entirely in your browser — nothing leaves your device.
Is the image compressor free?
Yes, free with no account.
