Validate

Validate

Check PDFs for specification compliance — the first command to run on any unknown file. Validates against PDF 32000-1:2008 (PDF 1.7) plus basic PDF 2.0 checks.

Command line

pdfcpu2 validate [-m strict|relaxed] [-l] [--opt] inFile...

Flag	Meaning
-m, --mode	relaxed (default): tolerates common spec violations; strict: pedantic
-l, --links	check for broken links
--opt	optimize resources (fonts, forms, images) during validation
--progress	print each input before validating it
inFile...	multiple files; - reads from stdin

pdfcpu2 validate in.pdf
pdfcpu2 validate -m strict in.pdf
pdfcpu2 validate -l *.pdf
cat in.pdf | pdfcpu2 validate -

Go API

package main

import (
	"context"

	"github.com/huzpsb/pdfcpu2/pkg/api"
	"github.com/huzpsb/pdfcpu2/pkg/pdfcpu/model"
)

func main() {
	ctx := context.Background()
	conf := model.NewDefaultConfiguration()

	// Simple pass/fail
	if err := api.ValidateFile(ctx, "in.pdf", conf, nil); err != nil {
		panic(err)
	}

	// Structured report you can inspect programmatically
	report, err := api.ValidateFileWithReport(ctx, "in.pdf", conf, nil)
	if err != nil {
		panic(err)
	}
	_ = report

	// Batch
	_ = api.ValidateFiles(ctx, []string{"a.pdf", "b.pdf"}, conf, nil)
}

Lower-level: api.ReadContextFile(ctx, inFile) + api.ValidateContext(ctx, ctxObj) give you full control over the parsed document — see Go API.
