Merge PDF files into a single document when you need one attachment, one archive, or one print job instead of a folder of separate PDFs.
Drop every file you want to combine, drag them into the final order, and export one clean PDF. PDFPeach runs entirely in your browser — nothing is uploaded.
How to merge PDF
- Drop two or more PDF files into the uploader (or pick them from your device).
- Drag whole files — or individual pages — into the order you want in the merged result.
- Click download to export the combined PDF.
You can keep adding files until the sequence looks right; the export always creates a new file and leaves your originals untouched.
Why merge PDF files in the browser
Combining PDFs on a website often means uploading contracts, scans, or client packs to someone else’s server. PDFPeach keeps that work on your device.
- No upload required — Files stay in the browser tab; they are never sent to PDFPeach servers.
- Order you control — Drag files and pages so cover sheets, exhibits, and appendices land where they belong.
- Free to use — Merge as many batches as you need without an account or paid plan.
- Fast local export — Processing happens on your machine, so large packs are not waiting on a remote queue.
When to merge PDFs
- Assemble a signed packet from several single-page signature PDFs.
- Bundle invoices, receipts, or statements into one monthly archive.
- Attach a multi-part application as a single upload for a portal that only accepts one file.
- Combine scanned chapters into one bookmarked-ready manuscript before you add bookmarks elsewhere.
- Join a cover letter PDF with a resume and portfolio samples for email.

How merging works here
Each uploaded PDF is loaded locally. You see thumbnails for pages across those files. Dragging reorders the sequence that will be written into the new document. When you export, pages are concatenated in that visual order into a fresh PDF — your source files are not overwritten.
Options you will use most
- Multi-file upload — Add several PDFs in one pass.
- Drag reorder — Move files or pages before export.
- Download — Save the combined result with a clear filename.
Limits and tips
Very large files (tens of megabytes with many pages) still process in the browser; keep the tab open until download finishes. If you only need a subset of pages from one file, use Extract PDF Pages first, then merge the smaller pieces.
Privacy
Merge runs in your browser — files are not stored on PDFPeach servers. Close the tab when you are done if you are on a shared computer.
Frequently asked questions
Is PDF merging free on PDFPeach?
Yes. Merging PDFs in the browser is free — no account, watermark on the tool UI, or upload fee.
Can I change the order of files before downloading?
Yes. Drag file cards or individual page thumbnails into the sequence you want. The download reflects that order.
Does merging upload my documents?
No. Combination happens locally in your browser. Files never leave your device for this tool.
Will my original PDFs be changed?
No. Merge creates a new combined PDF. Your source files stay as they were on disk.
How is merge different from organize?
Merge starts with multiple PDFs and builds one file. Organize PDF Pages reorders pages inside a single document (and can insert blanks or remove pages). Use both when you first combine packs, then tidy page order.
