Compress Image to 50 KB

Get a JPG, PNG or WebP under 50 KB for an ID photo, avatar or signature. Quality first, then size in pixels, all in your browser. Nothing is uploaded.

Compression

Each image as good as it can be under the size: JPG and WebP lower their quality, PNG its colors, and a picture is made smaller in pixels only if that isn't enough. Images already under it stay as they are.

Runs in your browser. Nothing you enter is uploaded.

How to use

This page shrinks each image you add until it is under 50 KB, on your own device, for the portals that set that limit on an ID photo, a signature or a profile picture.

  1. Drop the picture on the box or choose it; several at once are fine. A paste with Ctrl+V works too.
  2. Target size is already selected and the box says 50. Leave it, or type another number if the form you're filling asks for 40 or 60.
  3. Each image is tried at lower and lower quality until one version fits under 50 KB. A photo straight from a phone is several megabytes, so quality alone rarely gets there: the picture is then reduced in pixels as well, by just enough.
  4. The row under the picture tells you what happened: the new size, and the new width and height if it had to shrink.
  5. Look at the comparison before you download. Faces and signatures stay readable at 50 KB; fine print in a document scan may not, so check it at Actual size.
  6. Download the file, or every file as a ZIP.

A limit of 50 KB suits small pictures. A head-and-shoulders photo at 600 by 600 pixels fits comfortably as a JPG; a wide landscape has to lose more. If a portal also sets a size in pixels, say 413 by 531 for a passport photo, run the picture through the image resizer first, then compress it here.

PNGs are cut to fewer colours before they're shrunk in pixels, which keeps a scanned signature crisp. WebP files get the same treatment as JPGs.

Frequently asked questions

Will a 50 KB photo be good enough for an ID or passport portal?

Yes for the portals that ask for it: they display or print the photo small. A JPG around 600 pixels on each side holds a clear face in 50 KB. The page lowers quality first and the pixel size only if it must, so the face keeps as much detail as the limit allows.

Why did my picture get smaller in pixels?

Because no quality setting could fit it under 50 KB at its original width and height, which is normal for a phone photo of 4,000 pixels across. The page shrinks it only as much as needed and tells you the new size.

My file is 48 KB and the form still rejects it. Why?

Some forms count kilobytes as 1,000 bytes rather than 1,024, so 48 KB here could be read as 49 KB there. Type 45 into the box to leave room, and check whether the form also wants a particular format or size in pixels.
