Where you meet a 200KB limit
The National Scholarship Portal asks for each document as a PDF or JPEG of no more than 200 KB. Many state scholarship portals, university admissions and recruitment forms use the same limit for income, caste and marks certificates.
Combining certificates under 200KB
Some portals want several certificates in a single file. Join them with Merge PDF, which has a box for a size limit: type 200 and it merges and compresses in one go. Our guide on combining certificates into one PDF walks through it.
Why scanned certificates are so large
A phone camera records 10 to 12 megapixels and full colour, which is far more than a portal needs. A certificate only has to be readable, and 120 to 150 dpi in grey-scale is plenty for that. Ticking black & white often halves the size and every word stays clear.
Why your file stays private
Compress PDF to 200KB runs entirely inside your browser. Your file is read from your device, processed in memory and saved back to your device. It is never uploaded to GreenPDFs or anyone else, so you can use it with Aadhaar, marksheets, bank statements and other personal documents. How in-browser processing works.
Frequently asked questions
Can every PDF be compressed to 200KB?
Most can. Typed PDFs and light scans get there easily. A long scan full of photos sometimes can't, and in that case the tool shows the smallest size it reached and suggests what to try next, such as removing pages, cropping margins or splitting the file.
Will the text still be readable?
The tool first tries a lossless optimisation, which keeps text sharp and selectable. If that isn't enough, it saves the pages as images at the highest resolution that still fits 200KB, then shows you a preview to check before you upload.
Does it work on a mobile phone?
Yes. Open this page in Chrome or Safari on Android or iPhone, pick the PDF from Files or Downloads, and download the result. There is nothing to install.
Is my document uploaded anywhere?
No. GreenPDFs works inside your browser, so the PDF stays on your phone or computer. You can use it for Aadhaar, marksheets and other personal documents.
What is the NSP document size limit?
The NSP FAQ says each document should be a PDF or JPEG and no larger than 200 KB. Check your scheme's instructions in case they differ.
