Compress PDF to 150 KB
The target is already set to 150 KB: choose your PDF and download it at 150 KB or under. A 150 KB limit sits between the strict 100 KB caps and the more relaxed 200 KB ones, and some recruitment, admission and scholarship forms use it for each certificate or ID proof. A one or two page scan normally fits.
How to use Compress PDF to 150 KB
- Choose the PDF you need under 150 KB. The target size is already filled in.
- Start compression. Images are shrunk first, and pages are only turned into images if that is the only way to reach the target.
- Download the file. If it can't reach 150 KB without becoming unreadable, you get the smallest readable version and a note saying so.
Frequently asked questions
How do I reduce a PDF to 150 KB?
Open this page, choose the file and press Compress. Most single-page scans reach 150 KB on the first pass with the text still easy to read. A two-page scan may need its images re-encoded at a lower quality, and the result tells you if any page had to be flattened.
My scan is 2 MB. Can it really get down to 150 KB?
Usually, for one or two pages. Phone scans are saved at a far higher resolution than an upload form needs, so most of that size is detail nobody will see on screen. Resampling removes it while keeping printed text legible.
