Good use cases

• Preparing packets for email without a desktop Acrobat license
• Cleaning scans before sharing with a client
• Extracting or rotating pages from a long statement
• Building a single PDF from images or multiple files

Alternatives (and when to pick them)

• Desktop apps — best for heavy daily editing with lots of files
• OS built-ins — fine for occasional jobs when you already know the workflow
• Upload-based websites — convenient, but avoid for sensitive inputs
• Toolkase browser tools — fast, private-by-default for one-off and recurring light work

Tips for private PDF work

• Prefer desktop browsers for large files; phones can run out of memory.
• Keep originals until you confirm the download looks right.
• Chain tools when needed — for example split first, then merge, or rotate before exporting images.
• Treat upload-based PDF sites as a last resort for IDs, contracts, and tax documents.
