Crop & Resize PDF — Change Page Size Online
Two powerful modes for adjusting PDF page dimensions without rasterization.
Crop Mode
Trim margins from any or all sides using precise millimetre inputs. Uses setCropBox() for truly lossless cropping — no quality loss whatsoever.
Resize Mode
Resize pages to A3, A4, A5, Letter, Legal, or custom dimensions. The original page content is embedded as a vector object into the new page size — vector-preserving, non-rasterized. Choose Fit, Fill, or Shrink Only scaling.
Output Verification
Every output is verified with page count assertion, SHA-256 fingerprint, and (for resize) dimension verification against the target size.
