Clean Excel and CSV files without uploading them

Combine PDFs and photos into one PDF

Check a PDF before uploading it to an application

Check PDF file size, page count and password protection against the limits you enter. Local processing with clear, limited results.

Check whether PDF files match a saved file record

Extract and reorder PDF pages locally

Keep selected PDF pages, change their order and rotate sideways scans. Create a separate PDF in your browser without uploading the original.

Add page numbers and a contents page to PDFs

Assemble a document pack with a contents page and reference numbers. Keep source files unchanged and add numbering below the existing page content.
