Resize

Resize selected pages of inFile by scale factor, to a standard paper size or to specific page dimensions. Choose whether to preserve the requested page orientation and allow additional content rotation. Have a look at some examples .

Usage

pdfcpu resize description inFile [ outFile ] [flags]

Flags

name	description	required
p(ages)	selected pages	no

Common Flags

Arguments

name	description	required
description	configuration string	yes
inFile	PDF input file, use `-` to read from stdin	yes
outFile	PDF output file, use `-` to write to stdout	no

Description

A configuration string with input parameters for the resize command.

parameter	values
scalefactor	0.0 < s < 1.0 or s > 1.0
dimensions	(width, height) in user units eg. ‘400 200’
enforce	preserve requested output-page orientation: on/off true/false t/f
formsize, papersize	paper size to be used. Append L or P to enforce landscape/portrait mode
rotate	allow additional best-fit content rotation: on/off true/false t/f; default on
border	draw the fitted content boundary: on/off true/false t/f
bgcolor	color

enforce:on preserves the requested output-page orientation. The P and L paper-size suffixes also select and enforce that orientation. Without enforcement, the destination follows the source orientation.

rotate:on is the default: when orientation is enforced, resize may turn content by 90 degrees for a better fit. Use rotate:off to preserve its displayed orientation, scale proportionally and center it in the destination. This does not suppress normalization of an existing page-level or inherited /Rotate value. Annotation rectangles and quad points follow the same complete transform as the content. The option has no effect on scale-only resizing or sizing by just width or height.

Direct Go callers can set model.Resize.DisableContentRotation to true. Its zero value retains best-fit rotation.

Examples

Enlarge pages by doubling the page dimensions, keep orientation.

$ pdfcpu resize "scale:2" in.pdf out.pdf

Shrink first 3 pages by cutting in half the page dimensions, keep orientation.

$ pdfcpu resize "sc:.5" in.pdf out.pdf --pages 1-3

Resize pages to width of 40 cm, keep orientation.

$ pdfcpu resize -u cm -- "dim:40 0" in.pdf out.pdf

Resize pages to A4, keep orientation.

$ pdfcpu resize "form:A4" in.pdf out.pdf

Resize pages to A4 and enforce orientation (here: portrait mode), apply background color.

$ pdfcpu resize "f:A4P, bgcol:#d0d0d0" in.pdf out.pdf

Resize mixed portrait and landscape pages to A4 portrait while preserving displayed content orientation. Landscape content fits the A4 width and is centered vertically, leaving unused space above and below.

$ pdfcpu resize 'form:A4P, rotate:off' in.pdf out.pdf

Resize pages to 400 x 200 points, keep orientation.

$ pdfcpu resize "dim:400 200" in.pdf out.pdf

Resize pages to 400 x 200 points, enforce orientation.

$ pdfcpu resize "dim:400 200, enforce:true" in.pdf out.pdf

Resize a streamed PDF and upload the result:
