Compress an image to 50 KB

50 KB is the usual ceiling for a profile photo on job sites, a passport-style photo on visa and university forms, and a scanned ID card on many government portals. It is small enough that guessing a quality slider rarely lands under it on the first try, and large enough that the picture should still look good.

The tool finds the answer instead of guessing: it keeps the picture at full size if the best quality fits, and otherwise reduces it just enough, so the result is the largest, sharpest picture that is still under 50 KB. A typical phone photo comes out about 650 × 450 pixels, which is more than any of these forms displays.

How to get an image under the limit

  1. Upload the image: JPG, PNG, WebP, HEIC from an iPhone, and more.
  2. 50 KB is already selected. Add a minimum or exact dimensions under More options if the form asks for them.
  3. Press Compress, check the size and dimensions on the result page, and download the JPG.

What the file will be

  • Under 50 KB whichever way the portal counts a kilobyte.
  • The largest picture that fits, not a fixed small one: a small original stays at its size.
  • An image already under 50 KB is never made bigger; it is saved upright and without its metadata at the best quality that fits in its own size.
  • JPG by default, or WebP when a site accepts it, which keeps more pixels at the same size.

Questions about 50 KB images

Because below a quality of about 70 a JPEG starts to show blocks and halos, while a slightly smaller picture at a good quality looks clean at the size a form shows it. The tool keeps the quality at 72 or above and reduces the dimensions instead, and goes lower only for pictures that cannot fit otherwise.
Usually at its full size: in our test a card scanned at about 1,000 pixels across fitted under 50 KB without being reduced, and printed text stayed sharp. Scan only the card rather than the whole page, so all of the 50 KB goes to it.
JPG, unless the site says it accepts WebP. Every portal takes JPG; WebP keeps more detail at the same size but some older forms refuse it.
Yes. HEIC photos are read on the server, turned upright and converted to standard colours before they are compressed, so the result looks the way the photo looked on the phone.
