Validate

Any PDF file you would like to process with pdfcpu needs to pass validation.

This command validates inFile against:

PDF 1.7: PDF 32000-1:2008
PDF 2.0: PDF 32000-2:2020 (ongoing task!)

Validation can also check for broken links.

Have a look at some examples.

Usage

pdfcpu validate inFile... [flags]

Flags

name	description	required	values	default
m(ode)	validation mode	no	strict, relaxed	relaxed
l(inks)	check links	no

Common Flags

Arguments

name	description	required
inFile	PDF input file	yes

Mode

Strict

This mode validates against the PDF specification covering all PDF versions up to 2.0.

Relaxed

This is the default mode for validation.
It behaves like strict but does not complain about common seen violations of the specification by PDF writers.

Examples

An example using strict validation:

$ pdfcpu validate test.pdf --mode strict
validating(mode=strict) test.pdf ...
validation ok

An example using default validation:

$ pdfcpu validate test.pdf
validating(mode=relaxed) test.pdf ...
validation ok

Check for broken links:

$ pdfcpu val PDF32000_2008.pdf -l
validating(mode=relaxed) PDF32000_2008.pdf ...
