About This Tool

PDF Resize Tool analyzes an input PDF and adjusts page dimensions or scales content to match a target size. It is designed for users who publish reports, theses, marketing collateral, or any document that requires consistent page sizes across multiple files.
Conceptually, the tool reads the original page media boxes, computes a scale factor based on target dimensions, and applies a uniform transform to each page. It can operate in fit-to-page mode (scale content so the page fits within the target bounds) or in exact-scale mode (uniformly scale pages by a specified factor). Optional features preserve metadata and bookmarks when supported.
Beneficiaries include students, researchers, publishers, and compliance teams; the tool differentiates itself through batch processing, support for major paper sizes, preservation of metadata and color spaces, and predictable output. Typical use cases include preparing reports for printing, aligning academic theses for submission, and standardizing document sets for archiving or distribution.

How to Use

  1. Upload the PDF and select a resize mode (fit or scale).
  2. Enter target width and/or height in mm or inches, and choose the unit.
  3. Enable optional settings like preserving metadata or enabling batch processing if handling multiple files.
  4. Run the resizing operation to generate a new PDF file.
  5. Download and verify the resized document for page size accuracy.
