Compress a PDF to 150 KB

150 KB is a common cap for certificates and ID proofs on registration portals. Two or three scanned pages usually fit.

Getting a PDF under 150 KB

Registration and scholarship portals often allow 150 KB per document: an ID proof, a caste or income certificate, a fee receipt. Two or three scanned pages usually fit with the text still easy to read.

We run a lossless cleanup first, then step the page images down in resolution and JPEG quality together until the file is under 150,000 bytes. We stop at the first step that fits, so nothing is squeezed harder than it needs to be.

Tips

  • Front and back of an ID card fit comfortably on one page. Put them side by side before scanning.
  • Check stamps, seals and signatures in the result. Fine, faint marks are the first thing to blur.
  • If the portal asks for a PDF but you have a photo, convert it to PDF first, then compress it here.

How it works

  1. 1

    Drop your file

    A PDF or an image. It goes over an encrypted connection and nowhere else.

  2. 2

    Pick your limit

    Choose the size the form asks for. We start with a cleanup that changes nothing you can see.

  3. 3

    Download it

    If it needs more, we find the gentlest quality setting that still fits, and delete everything soon after.

Questions

Is it free?

Yes. There is no sign-up and no watermark.

What happens to my file?

It is processed on our server and deleted automatically: the original 5 minutes after the run finishes, the compressed file after 10. A file you upload but never compress is deleted within 30 minutes. You can also delete everything right away with Delete now.

Will it look worse?

We try a lossless cleanup first, which does not change how the file looks. Only if that is not enough do we lower image quality, and we pick the gentlest setting that still fits your size.

What if my file cannot get that small?

You get the smallest version we could make and a clear note saying so, instead of a file that silently misses the limit.

Why does the size page aim a little under its limit?

Some sites count a kilobyte as 1000 bytes and others as 1024. We aim under the stricter one, so a 200 KB page aims for 200,000 bytes and the file passes either way.
