Crop PDF.

Manual crop is the starting mode. Move or resize the selection while inspecting the page; avoid cutting through letters, handwritten additions or page references.

Apply the same relative crop throughout only when the margins are consistent. Different source sizes can produce different physical output dimensions from the same relative selection.

Auto · Fit each page analyzes the visible page, then adds padding around the detected content. Start with the default padding and adjust it when a heading, stamp or faint note needs more space.

Detection is based on visible marks, not recognition of meaningful text. Shadows and scan noise can widen the crop, while very faint marks can be missed. Review the suggested boundaries before export.

Auto · Same size considers the content across the document and uses a shared physical crop. Overlay all pages helps you inspect the combined extent before settling on a frame.

Content stays at its original scale. The common frame can include extra whitespace on a sparse page; it is not a page-resizing or text-reflow tool.

The output changes page boundaries. Existing text can remain selectable and original image pixels are not resampled just to crop a margin. A scanned page still needs OCR to gain recognized text.

Inspect annotations and forms in the downloaded copy. If a complex annotation prevents a safe shared-frame export, try Manual crop or Fit each page.
