How to compress an image to a size in KB
- Type the maximum size in KB, for example the limit of the form you need to fill in.
- Drop your images on the box above, or click Choose files. You can add many at once.
- Download each image, or all of them in a single ZIP file. Under each file you can see its size before and after.
Questions
Are my files uploaded?
No. Everything runs inside your browser on your own device. Your files never leave it.
How does it reach the size I asked for?
It looks for the highest quality that fits under your limit. If the image does not fit even at low quality, it is also made smaller, keeping its proportions, and the page tells you the new size in pixels.
What size is a KB here?
1 KB is 1,000 bytes. A file under 200 KB on this page is therefore also under 200 KB for sites that count 1 KB as 1,024 bytes.
What format do I get back?
JPG and WebP images stay in their format. PNG, HEIC and AVIF images become JPG, or WebP if they have transparent areas, so the transparency is not lost.
What if my image is already small enough?
If a JPG or WebP is already under the limit, you get the same file back, untouched. The result is never larger than the original in the same format.
What happens to the location and other metadata?
Only the image is kept. Metadata such as the location where a photo was taken, the date and the camera model is not copied to the new file.
