About Merge PDF
Merge PDF combines multiple PDF documents into a single file, in the exact order you choose. Drop your files in, drag the rows to set the sequence, and download a single combined PDF in seconds.
The tool runs entirely in your browser using pdf-lib. Your documents are never uploaded — we don't see them, don't store them, and don't keep any logs of file names. That makes it safe for contracts, financial statements, medical records, and other sensitive documents you wouldn't want to send to a server.
Unlike sites that watermark merged output or cap free use after a few merges per day, Utilix Merge PDF is unlimited and watermark-free for personal and commercial use. There's no signup, no cookie wall, and no upload progress bar — because nothing is uploaded. The merged PDF preserves all original page sizes, fonts, embedded images, and form fields exactly as they appear in the source files.
How Merge PDF works
- Drop or pick the PDF files you want to combine. Up to 5 files at a time on the free tier (50 on Pro).
- Drag the file rows up or down to set the order they should appear in the merged document.
- Click Merge. The tool reads each PDF with pdf-lib, copies pages into a new document, and re-emits a clean PDF.
- Download the combined file. The original files on your computer are untouched.
When to use Merge PDF
- Combine a cover letter, résumé, and references into a single job-application packet.
- Stitch scanned receipts into one expense report before submitting to finance.
- Join chapter-by-chapter exports from a writing app into a complete manuscript.
- Merge a signed signature page back onto the original contract.
- Bundle multiple invoices for the same client into a single statement.
- Combine multi-page bank statements for tax filing or loan applications.
