Tips for reaching 200KB on stubborn PDFs
If your PDF has multiple pages, split it first using our Split PDF tool and compress only the required page. A 4-page marksheet compressed to a single-page certificate will easily reach 200KB. Scanned documents at 300 DPI are the most common case — our tool resamples images to 96–120 DPI which typically achieves 200KB on 1–2 page documents.
How to compress a PDF to 200KB (3 steps)
Drop your PDF into the tool above or click Choose PDF. For best results under 200KB, use a single-page PDF (marksheet, certificate, or Aadhaar).
The target is pre-set to 200KB. Click Compress PDF to 200KB. For multi-page PDFs that won't reach 200KB, try splitting out just the required page first.
Download and upload to NTA, DU, or your state portal. If the portal still rejects, try our 100KB compressor.
Frequently asked questions
Can a multi-page PDF be compressed to 200KB?
It depends on the number of pages and content type. A 2-page text-based PDF can usually reach 200KB. A 4-page scanned document at 300 DPI rarely will — split it to the required page first using our Split PDF tool, then compress the single page.
NTA rejected my PDF even after compression — what now?
NTA portals sometimes verify that the PDF contains a valid image (not blank pages) in addition to checking file size. If compression causes blank-looking pages, try compressing at a higher quality setting. Also ensure your original scanned PDF has clear, well-lit content before compressing.
Is the compressed PDF accepted as a valid document?
Yes. The PDF is a valid PDF file with your document rendered as JPEG images inside. It opens in any PDF viewer and is accepted by all standard portal upload systems. The content is visually identical — only the file size is smaller.
