Compress PDF to 100 KB
The target is already set to 100 KB: choose your PDF and download it at 100 KB or under. Exam registration forms, scholarship sites and many government portals cap certificate uploads at 100 KB. One to three scanned pages usually fit at this size while staying readable.
How to use Compress PDF to 100 KB
- Choose the PDF you need under 100 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 100 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 100 KB?
Open this page, choose the file and press Compress. Text-only PDFs often drop under 100 KB with no visible change. Scans are re-encoded at a lower image quality until they fit, and you are told if the file still comes out larger.
Why does a portal reject my PDF even though it says 100 KB?
Some portals count 100 KB as 100,000 bytes rather than 102,400. Set a slightly lower target, such as 95 KB, to stay safely under either reading.
