Are my documents safe when using this merger?

Yes, your documents are completely safe because all merging processes run locally in your browser memory using client-side JavaScript. No files are ever uploaded to external databases or servers, protecting sensitive financial statements, business contracts, and personal IDs from leaks.

Can I choose specific pages to merge from a PDF?

Yes, you can expand any uploaded PDF in the queue to select or deselect individual page indexes to include. The tool compiles only your specified page selections into the final document instead of forcing you to merge the entire file.

How do I fix upside-down or sideways pages before merging?

You can rotate individual pages in 90-degree increments by clicking the rotation control buttons on each page thumbnail in the expanded page panel. The final merged PDF automatically preserves these customized rotation configurations to fix upside-down scans.

Is there a daily usage or file size limit for PDF merging?

There are no daily usage limits, file count restrictions, or file size caps on this platform because all parsing executes locally on your device. Large batch merges are limited only by the amount of physical memory available on your machine.

Can I generate a table of contents in the merged file?

Yes, checking the Table of Contents option prepends a new index page containing clickable links for each file start page. Users can click any list item to jump directly to that section in the merged document.

Common Use Cases for a PDF Merger

Compiling multiple distinct records into a single file simplifies sharing, storage, and presentation. Businesses and individuals regularly encounter scenarios where merging documents is essential:

Consolidating Invoices and Receipts

Accounting teams and freelancers frequently need to compile separate invoices, receipts, and expense statements into a unified PDF file before submitting them for tax returns or corporate reimbursements.

Onboarding and Application Paperwork

Job applicants and new hires often need to package resumes, cover letters, reference letters, and tax forms into a single consolidated PDF file to submit to HR portals that accept only one document link.

Assembling Academic or Research Portfolios

Students and researchers regularly compile individual chapters, articles, charts, and appendices into a unified book layout. Adding a clickable Table of Contents (TOC) ensures readers can easily navigate long documents.
