A practical guide to pdf workflows
The best tool is the one that matches the input, decision and destination—not simply the broadest label.
Choose page operations before format conversion
If a PDF only needs pages reordered, removed, rotated or combined, use a page-management tool and preserve the document format. Conversion is better reserved for editing content in another application, extracting information or creating a PDF from a different source.
Balance file size, quality and searchability
Compression may downsample images or remove redundant data, so inspect small text and diagrams after processing. OCR adds a searchable text layer to scans but can misread handwriting, unusual fonts or low-contrast pages. Keep the original when document fidelity matters.
Handle forms and sensitive documents carefully
Signing, redaction, password protection and metadata removal have different purposes. A black rectangle is not necessarily secure redaction, and a password does not resolve every distribution risk. Review the output, confirm the intended protection and follow organizational retention policies.

Processing should match the task
Catalogue search runs locally in your browser. Functional tools will identify when work can stay browser-local and when a server, authorized public data source or semantic service is necessary. No universal privacy or outcome guarantee is implied.

Helpful answers
PDF questions
Clear guidance for choosing and using the catalogue responsibly.
How can I reduce a PDF file size?
Use Compress PDF, then compare visual quality, page count and the resulting file size before sharing the output.
What is the difference between split and extract pages?
Splitting divides a PDF into separate files; extraction creates a new file from selected pages while leaving the original intact.
Does OCR make a scan editable?
OCR creates machine-readable text, but layout and recognition errors may still require correction or export to an editable format.
Will conversion preserve complex formatting?
Not always. Fonts, forms, columns, equations and embedded media can change, so review converted documents carefully.
Can a damaged PDF always be repaired?
No. Repair tools can recover some structures, but severe corruption or missing data may be irreversible.
What is PDF/A?
PDF/A is a family of ISO-standardized profiles designed for long-term preservation with specific restrictions and conformance levels.
Is removing metadata the same as redacting content?
No. Metadata cleanup removes document properties; redaction permanently removes selected visible or hidden content when correctly applied.
Should I upload confidential PDFs?
Check the processing and privacy note on a functional tool. Prefer browser-local workflows where feasible and follow your organization’s rules.
