Compress Image to a Target Size (KB)

Shrink any photo to an exact file size in kilobytes — free, no sign-up, no watermark. This page targets ~100KB, the size most online forms want. Need a different limit? Pick a target below.

Why use this compressor

• Hits your target size

  The tool automatically lowers quality — and downscales if needed — until the file fits under the KB limit you need.

• Sharp when it fits

  If the photo fits at full size, it gets the highest quality that does; if not, it is saved at low quality and shrunk until it fits.

• Made for forms & WhatsApp

  Ideal for government portals, exam applications, job forms and sending photos on WhatsApp.

• Free & private

  No sign-up, no watermark. Your image is processed on our server and deleted automatically after 2 hours.

Need a transparent cut-out instead? Try the Background Remover. Making an ID photo? Use the Passport Photo Maker.
