Compress PDF to 100 KB
Many application portals reject documents over 100 KB. Bring your PDF under the limit in one step, as clear as the size allows.
How to use it
- Choose the PDF you need to upload.
- It is compressed to 100 KB or less straight away. Tick black and white for scans if you need it smaller and sharper.
- Download it and upload it to your form.
Where 100 KB limits appear
Exam registrations, scholarship and job portals, and government services often limit each document to 100 KB: certificates, mark sheets, ID cards, birth certificates and proof of address.
One page or several?
A single scanned page fits comfortably in 100 KB. For three or more pages, black and white makes a big difference — and if the form allows separate uploads, split the PDF and upload each page on its own.
Frequently asked questions
Are my documents uploaded?
No. Everything happens inside your browser on your own device, so your documents are never sent to a server. That matters for ID cards, certificates, bank statements and contracts.
My result says it can’t get under 100 KB.
That happens with many pages of detailed colour scans. Tick black and white, remove unneeded pages with Split PDF, or check whether the form allows a larger file.
Can I compress a photo of a document instead?
Yes — turn it into a PDF with JPG to PDF, then compress it here.
