How to use Compress Image
- 1
Add an image
Choose a supported image or batch. Originals remain unchanged while you prepare new copies.
- 2
Compare the result
Use a quality preset and inspect Before and After. The preview reports the actual output size, including when it is larger.
- 3
Fine-tune and download
More control offers a target size and maximum dimensions. Check the result and download the copy that balances size and detail.
Pick a format for the image you have
JPG is useful for photographs without transparency. WebP can keep transparency with lossy compression. PNG keeps transparency and uses lossless encoding, so lowering a quality slider will not shrink it in the same way. A target size is a goal, not a guarantee; reducing dimensions can help when quality changes alone are not enough.
Common questions
Can I compress to an exact KB size?
You can set a target per image under More control. The tool attempts to meet it within the allowed quality range, but some files need smaller dimensions or a different output format.
Will my transparent background stay transparent?
Use PNG or WebP when you need transparency. JPG does not support transparent pixels. Always inspect the preview before downloading.
Why is the result larger than the original?
An image may already be well optimized, or another encoder may produce a larger file. The preview reports that result rather than promising a reduction. Try another format or smaller dimensions, or keep the original.
