Best for this tool
Merge is best when you need one clean packet instead of a stack of loose files. It works well for resumes, proposals, contracts, exhibits, and monthly reports.
- Combining reports, invoices, and supporting files into one handoff
- Building client packets before review or signature
- Putting resumes, cover letters, and portfolios into one PDF
Client packet building
Pull contracts, exhibits, and backup docs into one ordered PDF before you send it out.
Application bundles
Combine a resume, cover letter, and work samples so the reviewer gets one clean file.
Monthly reporting
Merge statements or summaries first, then compress the final PDF if it needs to fit email limits.
Why Process PDFs Locally?
Supported workflows process document bytes in the browser without a document-byte upload to LocalPDF. Device, browser, extension, download, storage, and later-sharing risks remain separate boundaries.
