Combining PDFs sounds like a two-click task and somehow takes 20 minutes when you don't have the right tool. Adobe Acrobat can do it, but the free tier can't. Google Docs mangles formatting. Most free websites add watermarks or cap you at two files. Here's a faster way.
When you need to merge PDFs
- Combining a cover letter and resume into one file before sending a job application
- Putting together pages your scanner split into separate files
- Attaching multiple invoices as a single PDF to an expense report
- Packaging a contract with its addenda and signature pages
- Sending a portfolio or proposal as one file instead of a folder of attachments

Merge PDF FreeOrder matters — sort before you merge
The merged PDF reflects the exact sequence of files you upload. If you drop five documents at once, check the thumbnail order before clicking Merge. Drag any file to reposition it. Getting the order right before merging saves you from splitting the file apart and starting over.
Tip: Rename your files with a number prefix before uploading (01-intro.pdf, 02-body.pdf, 03-appendix.pdf) and your operating system will sort them automatically when you select them all.
File size after merging
A merged PDF is roughly the sum of all source files. A 1 MB resume and a 600 KB cover letter produce about a 1.6 MB combined file. If the total size matters (email attachment limits, upload caps on job boards or portals), compress the merged file in the same browser tab before downloading.
Merging PDFs that have passwords
Password-protected PDFs need to be unlocked before merging. Upload each protected file to the Unlock PDF tool, enter its password, download the unlocked version, then add those files to the merger. You can't merge a locked PDF directly.
What merging preserves and what it doesn't
Merging keeps all text, images, and page layout intact. Each source file's pages appear exactly as they were. Bookmarks and interactive form fields from the original documents may not carry over, depending on how the source files were created. For most everyday purposes, that doesn't matter. If you need to preserve a complex form structure, test the output before sending.
Page size mismatches
If you merge an A4 document with a US Letter document, each page keeps its original dimensions. The final PDF will have mixed page sizes. Most PDF readers handle this fine, but if you need all pages to match, open the merged file in the PDF editor and adjust individual pages before downloading.
Merging many files at once
EvrythingPDF's merger handles batches of files without a cap. Upload ten, twenty, or thirty PDFs at once. Browser memory is the practical limit, which is rarely an issue unless you're working with very large scanned documents. For batches of scanned files, compress each file first, then merge.
