Splitting a document across several PDF files — a scanned signature page here, a cover letter there — makes it harder to send, print or archive as one thing. This tool combines two or more PDF files into a single document, preserving each page exactly as it appears in the original files, in the order you upload them.
Everything happens directly on the server for your request and the merged file is handed straight back to you — there's no account, no email requirement, and no limit on how many times you merge files.
How it works
Upload two or more PDF files (up to 10 at a time, 20MB each). The tool reads every page from each file in the order you added them and combines them into one new PDF, preserving each page's original size and orientation. Download the merged file as soon as it's ready.
- Upload two or more PDF files, in the order you want them merged.
- Remove any file you added by mistake.
- Click Merge and download the combined PDF.
Examples
Combining a contract and its signature page
A signed contract exported as one PDF and a separately scanned signature page as another are merged into a single file — sent as one attachment instead of two.
Assembling a multi-part report
Three PDF sections of a report, each exported separately from different source documents, are merged in order into one complete report file.
Who should use it
- Combining a document and its separately scanned signature page.
- Assembling a multi-part report from several individually exported PDF sections.
- Merging multiple scanned pages into one file for archiving or sending.
Industry applications
- Legal and contract management
- Office administration
- Publishing and reporting
- Scanning and archiving workflows
Advantages
- No account, watermark, or limit on how many merges you run.
- Preserves each page's original size and orientation exactly.
- Gives a specific error naming which file failed, instead of a generic failure.
Limitations
- Doesn't support reordering pages within a single source file — only the order files are uploaded in.
- Can't open password-protected or corrupted PDFs.
- A 20MB-per-file, 10-file limit per merge.
Common mistakes to avoid
- Uploading files in the wrong order and not noticing until after downloading the merged result.
- Trying to merge a password-protected PDF without first removing the password.
- Assuming merging will resize or reorient mismatched page sizes to match — it preserves each page as-is.
Best practices
- Double-check the upload order matches the order you want the final document to read in.
- Remove passwords from any protected PDFs before merging, since the tool can't open encrypted files.
- Keep a copy of your original individual files until you've confirmed the merged PDF looks correct.
Tips
- Rename your files with a numeric prefix (01-, 02-, ...) before uploading if your browser's file picker doesn't preserve your intended order.
- If a merge fails on one specific file, try opening that file alone first to confirm it isn't corrupted or password-protected.
