Compress image
Make photos and scans small enough for upload forms. Pick a target size and get the sharpest image that fits under it. Your images are compressed on your own device and never uploaded.
How to compress an image
- Choose your images. Photos, scans, signatures — one or many, JPG, PNG or WebP.
- Pick the size. Choose 50, 100, 200 or 500 KB, or type your own limit.
- Press “Compress”. Download each image, or all of them as a ZIP.
Good to know
- Private — images are compressed by your own browser. Nothing is uploaded, so it works for photos of ID cards and certificates too.
- The sharpest image that fits — quality is lowered only as far as needed, and the image is made smaller in size only if quality alone isn't enough.
- Already small enough? An image already under the target is kept exactly as it is.
- Exact pixel size needed? Set “longest side at most”, e.g. 600 px, and the image is resized before compressing.

Frequently asked questions
How do I compress an image to a specific size?
Choose your images, pick a target such as 50, 100, 200 or 500 KB (or type your own), press "Compress" and download. Each image comes out as the sharpest version that fits under the target.
Are my images uploaded?
No. Compression happens entirely in your browser, on your own device. Your images are never sent to our server.
Which formats can I compress?
JPG, PNG and WebP images, and anything else your browser can open. The result is a JPG, which every upload form accepts, or WebP if you prefer a smaller file.
Will the image lose quality?
As little as possible: the tool keeps the highest quality that fits a size you choose, and only reduces the width and height when it has to. Photos taken on a phone are turned the right way up.
Can I compress several images at once?
Yes. Add as many as you like; each is compressed to the same target, and you can download them one by one or all together as a ZIP.
