Compress a PDF under a size in KB
Shrink a PDF below the limit an online form asks for. Your file stays on your device.
Pages are saved as images, so text in the result can no longer be selected or searched. This suits scans, certificates and forms.
How to compress a PDF to 200 KB
- Choose your PDF or drop it into the box above.
- Type the maximum size the form allows, or tap 100, 200 or 500 KB.
- Click Compress and wait while the pages are processed.
- Download the smaller PDF and check that it is still readable before you upload it.
Why forms ask for small PDFs
Visa portals, university registration sites and job application forms often refuse files above 200 KB or 500 KB. A scan made with a phone is usually several megabytes, so it has to be reduced first.
How the tool reaches the size
It redraws each page as a JPEG image and tries several levels of sharpness. It keeps the sharpest version that fits under your limit, so the result is as readable as the size allows.
What if the result is hard to read?
A long document cannot always fit in a very small size. Try a larger limit if the form allows it, or split the document and upload only the pages that are required.
Is it safe?
Yes. The compression happens inside your browser. Your passport, diploma or bank statement is not sent to any server.
