Merging PDFs is one of the most common document tasks — combining a contract with its addenda, assembling a report from multiple sections, or consolidating scanned pages into one file. PDFree does it entirely in your browser, with no upload and no account.
Click Choose files or drag multiple PDFs into the drop zone at once. You can add as many files as you need — there is no limit.
Drag the file cards up or down to set the exact order the pages will appear in the final document. Reorder as many times as you like before proceeding.
Click Merge PDF files. Processing takes seconds (longer for very large files). The merged PDF downloads directly to your device.
Clients often sign the main agreement and amendments as separate files. Merge them into one PDF before archiving or uploading to a contract management system.
Many university portals accept only one PDF. Combine your cover sheet, paper body, appendices, and bibliography into a single submission file.
Merge an executive summary, charts, raw data tables, and supporting documentation into a single professional PDF to share with clients.
If you scanned a multi-page form one page at a time, merge all the individual page PDFs into a single document before submitting.

There is no hard limit. PDFree processes everything in browser memory, so you can merge dozens of files. For very large batches (50+ files or total size 500MB+), close other browser tabs to free up RAM.
Yes. PDFree uses pdf-lib, which copies pages at the PDF object level — fonts, images, vector graphics, and formatting are preserved exactly as in the originals.
No. Encrypted PDFs cannot be read or modified without the password. Remove the password first using a PDF tool, then merge.
No. Unlike SmallPDF (2 tasks/day free) or iLovePDF (daily limits), PDFree has no usage caps. Merge as many PDFs as you want, as often as you need.
No. Your files are processed entirely in your browser's memory. Nothing is sent to any server. Close the tab and the files are gone from memory — no trace on any server.
Yes. PDFree works in mobile browsers (Chrome for Android, Safari for iOS). Drag and drop is replaced by a file picker, and reordering works by tapping the up/down buttons.
