How to use this tool

  1. Choose an image and check its current size and dimensions.
  2. Enter the maximum KB or MB, and a minimum only if your form specifies one.
  3. Select the format, width, height and fit mode; process and compare the output.

What to check before downloading

Very small targets may be impossible at fixed dimensions. JPEG supports minimum-size padding; PNG and WebP may not meet a minimum. Padding adds bytes, not visual quality.

Common questions

Can I set 50 KB and exact dimensions together?

Yes. Enter 50 as the maximum with KB selected, then enter width and height separately. The tool preserves requested dimensions and reports when the byte target cannot be reached.

Do I need to upload files to a server?

No. This version processes selected files in your browser. Website assets still load from the hosting service. See our privacy information and file limits.
