    Questions

    How do I compress an image to a specific size, like 100 KB or 1 MB?

    Choose “Target file size”, enter the number and pick KB or MB, then add your images. Each one is saved at the highest quality that stays under that size. Forms count a kilobyte as 1,000 or 1,024 bytes, so results stay under the smaller count (25 KB means at most 25,000 bytes here) and pass either way.

    Why did my image get smaller dimensions?

    When a size limit is tight, lowering the quality further would make the image look blocky. The tool scales it down instead and tells you the new size. To control the dimensions yourself, set a maximum width or height.

    Can I keep my PNG as a PNG?

    Yes: choose “PNG (fewer colours)”. The image is reduced to 256 colours (fewer, if a size limit needs it), which usually makes a PNG several times smaller and keeps its transparency. Photos with smooth gradients can show slight banding; WebP keeps those smoother at a small size.

    Which format should I choose?

    Leave it on “Best for each image” unless something requires a specific format. JPG is accepted everywhere; WebP is smaller and keeps transparency, and every current browser shows it.

    Does it remove metadata?

    Yes. Compressed files don’t include EXIF details such as GPS location and camera model, which also saves a little space. If an original is kept unchanged because it was already small enough, its metadata stays.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
