🔒 Your photo is processed inside your browser and is never uploaded.

How to compress an image to any size

  1. Tap choose a photo and pick one or more images from your phone or computer.
  2. Pick the target size (20 KB to 1 MB, or type your own) and, if you like, a maximum width.
  3. Tap Compress. Each photo is shrunk until it is under the limit, then tap Download.

The tool lowers JPG quality step by step and, only if needed, reduces the pixel size, so the result is as sharp as possible for the file size you asked for. The before/after sizes are shown so you can check the limit of the form you are filling.

Need exact pixel dimensions as well? Use the photo & signature resizer (presets for every major form) or the image resizer. For PDFs, use compress PDF to KB.

Why a photo is bigger than you expect

Phone cameras save 12–50 megapixel images that weigh 3–8 MB. A form only needs a 400–600 pixel photo, so most of that size is wasted. Compressing to 50–100 KB keeps a face perfectly clear on screen and in print at passport size.

Frequently asked questions

How do I compress a photo to 50 KB?

Choose the photo, select 50 KB as the target and tap Compress. The tool lowers the quality and, if needed, the dimensions until the file is under 50 KB, then you download it.

Will the photo still be clear?

Yes for forms and web use. Quality is reduced gradually and the pixel size only shrinks when the target cannot be met otherwise, so a face stays sharp at passport size.

Does it compress PNG files?

Yes, but a PNG is lossless so its size cannot be guaranteed. Pick JPG as the output to hit an exact KB target; PNG output only resizes.

Is my photo uploaded anywhere?

No. Compression happens in your browser with the canvas API — the image never leaves your device.

Can I compress several photos at once?

Yes, select multiple files. Each is compressed to the same target and downloaded separately.
