Increase PDF size
Government, legal, and academic portals often mandate that scanned certificates, degree marksheets, or caste certificates must be uploaded as PDF files with a minimum size of 100 KB, 200 KB, or 500 KB to guarantee high resolution. If your scanner compressed your single-page document to 60 KB, the portal will reject the upload. increasesize.in uses pdf-lib to insert harmless document padding comments and structures, bringing your PDF to the required size while guaranteeing it remains 100% valid and readable in Adobe Acrobat and web browsers.

How a PDF is built (objects and streams) and how padding keeps it valid
A PDF file is a structured binary document governed by ISO 32000 standards. It consists of a header (%PDF-1.x), an object catalog, a body containing page streams, a cross-reference table (xref), and a trailer ending with %%EOF. Simply appending raw bytes after %%EOF can corrupt the xref table in strict PDF parsers like Adobe Acrobat Reader. Our engine processes the PDF through pdf-lib, safely embedding inert metadata and appending standard structural comment lines before and after trailer markers. After expansion, the file is re-parsed and validated in-memory to confirm that all text layers, fonts, and embedded images remain perfectly readable.

Frequently asked questions
Yes. Because we use pdf-lib to maintain valid cross-reference (xref) offsets and official trailer comments, the PDF opens cleanly in Adobe Acrobat, Google Chrome, and mobile PDF viewers.
