PDF workflow guide
Choose the right PDF task before you start.
Similar PDF jobs can produce very different results. Pick the workflow that matches what you actually need, keep the original file until you verify the download, and review important documents in an independent PDF viewer before sharing them.
Merge, split or organize?
Merge PDF combines separate files into one document. Split PDF extracts a range or separates pages into smaller files. Organize PDF is the better choice when the pages are already in one PDF and you mainly need to reorder them. Remove Pages and Crop PDF are more precise when only selected pages need changing.
Compress without guessing.
PDF compression is a trade-off between file size and fidelity. Image-heavy documents usually offer more room for reduction than text-only PDFs. Very aggressive target sizes can reduce image clarity and may change searchable text, forms, links or accessibility features, so keep the source and inspect the result.
Edit, sign and inspect with the right tool.
Add Text, Add Image and Watermark PDF place visible content on pages without pretending to be a full desktop publishing editor. Sign PDF places a visual electronic signature; it is not a certificate-backed digital signature. Edit Metadata changes document properties, while Compare PDF helps review visible differences between two versions.
Protect, unlock and repair responsibly.
Protect PDF applies password-based security to a document. Unlock PDF requires the current valid password and should only be used when you own the file or have permission to remove protection. Repair PDF attempts recovery of damaged PDF structure but cannot guarantee that every corrupted object or missing page can be restored.
Understand how your PDF is processed.
AJN PDF uses different processing models depending on the task. Supported browser workflows can operate within the active session, while security, recovery or other advanced operations may use a temporary online request. Each public tool explains its current processing mode and important limits instead of making one privacy claim for every workflow.
