Why use this image compressor
- Private: your images are processed on your device and never uploaded.
- Fast: no waiting for an upload or download from a server.
- Free: no signup, no limit on how many images you add, no watermark.
- Flexible: compress several JPG, PNG and WebP images at once and convert between formats.
Smaller images make web pages load faster, save storage space, and make photos easier to send by email or upload to forms that have a size limit.
JPG, PNG or WebP: which should you choose?
JPG suits photos and gives small files at moderate quality. PNG keeps every pixel exact and supports transparency, but files are larger. WebP usually produces the smallest file for both photos and graphics and works in all modern browsers.
Frequently asked questions
Is this image compressor really free?
Yes. It is free to use, needs no account, and adds no watermark to your images.
Are my images uploaded to a server?
No. All compression happens inside your browser on your own device. Your images are never sent anywhere.
Which quality setting should I use?
A quality of 70 to 80 percent usually gives a much smaller file with little visible difference. Go lower for the smallest size, or higher if you need maximum detail.
Why does my PNG not get much smaller?
PNG stores every pixel exactly, so photos saved as PNG stay large. Lower the quality slider to reduce the number of colors, resize with the maximum width option, or convert photos to WebP or JPEG for much smaller files.
Which image formats are supported?
You can compress JPG (JPEG), PNG and WebP images, and convert between JPEG, PNG and WebP.
Will compressing reduce my image quality?
JPEG and WebP compression removes some detail to save space. At moderate settings the difference is hard to notice, and you can use the Compare button to check the result before you download.
