Overview
PDF Toolkit handles the document chores that usually tempt people into uploading contracts to an unknown website: combining files into one deliverable, extracting a page range, and reviewing or editing basic metadata. Processing happens in your browser with pdf-lib and a worker when available, under explicit size and page limits.

Why these tools
PDFs are the format most likely to contain something confidential, so local processing matters more here than anywhere else. Merge, split, and metadata review cover the majority of real requests, and the image helpers prepare the assets that end up inside those documents.

Frequently asked questions
- Are my PDFs uploaded to a server?
- No. Merging, splitting, and metadata edits run in your browser. That is the main reason to use these tools for anything contractual or personal.
- Can I open password-protected files?
- No. Encrypted PDFs fail with a clear error. Remove the password in a desktop application first, then process the unlocked copy locally.
- How do I control the merge order?
- Add each file in PDF Merger, then move rows up or down. The top of the list becomes the first page of the merged document, so verify the order before exporting.
- Does splitting remove hidden information?
- It removes the pages you excluded, but metadata and annotations on the remaining pages survive. Review metadata separately before sharing externally.
- What are the size limits?
- Each file is capped at 50 MB and 500 pages, with lower combined limits for merges. The caps appear under each file picker along with a mobile memory note.
