What the PDF merger does

Fast Processing

Merge multiple PDF files in seconds with optimized server-side processing. Two pages or two hundred, the merge runs at the same speed on Mac, Windows, iPhone or Android.

Easy Reordering

Drag and drop files into the exact sequence you need before creating the final document. Rearranging is instant and visual, so you can merge PDFs in the right order without Adobe Acrobat or any desktop software, just your browser and a few clicks.

Flexible Plans

Merge PDFs without watermark on any plan. Batch count and individual file size limits scale with your active tier, giving you the flexibility to combine everything from a handful of one-page forms to large multi-chapter manuscripts, no surprise restrictions.

Preview Before Merge

Review thumbnail previews of every uploaded PDF before exporting so you can catch ordering mistakes or duplicate files early. This visual check saves time compared to merging blindly and having to redo the process, especially when combining scanned documents or multi-page contracts.

Encrypted & Auto-Deleted

Every file is uploaded over an encrypted HTTPS connection and automatically deleted from our servers after you download the merged result. No documents are stored, indexed, or shared, making this a safe way to merge sensitive contracts, tax forms, or medical records online.

Any Device Support

Combine PDFs on Mac, Windows, iPhone, iPad, or Android, no app download or signup required. The tool runs in any browser, so you can merge PDFs from any device with a connection.

Common Use Cases for Merging PDFs

Combining Contract Pages

Merge signature pages, addendums, and exhibits into one final contract PDF. Lawyers and freelancers use this to send a single clean document to clients instead of multiple attachments.

Assembling Monthly Reports

Combine individual department reports, charts, and cover pages into one polished PDF for stakeholders. No need for Adobe Acrobat, upload, reorder, and download the merged report in seconds.

Merging Scanned Documents

Scanned receipts, ID cards, or handwritten notes often end up as separate files. Merge them into a single PDF so they're easier to email, archive, or upload to a portal.

Consolidating Invoices

Accountants and bookkeepers can combine monthly invoices, expense receipts, and purchase orders into one file for tax preparation or audit documentation, free online with no signup required.

Packaging Application Materials

Merge your resume, cover letter, transcripts, and reference letters into a single application PDF. Universities and employers often prefer one combined file over multiple attachments.

PDF Merger FAQ

Quick answers about merging multiple PDF files, page ordering, quality preservation, and file size limits.

How do I merge PDF files online?

Upload two or more PDF files using drag-and-drop or the file browser. Reorder them by dragging thumbnails into the sequence you want. Click Merge and download the combined PDF, the entire process takes seconds.

Is there a limit on how many PDFs I can merge?

There is no cap on how many PDFs you combine in one merge, add two or two hundred. The limit is per file: 50 MB without an account, 100 MB once you sign in free, and more on a paid plan. A merge counts as one conversion against your daily allowance, however many files went into it.

Will merging PDFs change the quality or layout?

No. Merging is a lossless operation that concatenates pages without re-encoding. Text, images, fonts, links, bookmarks, and form fields are preserved exactly as they appear in the originals.

Can I rearrange the page order before merging?

Yes. After uploading, drag and drop file thumbnails to set the order. The final merged PDF follows your custom sequence from top to bottom.

Can I merge password-protected PDFs?

PDFs with a user password (open password) need to be unlocked before uploading. PDFs with only an owner password (edit restriction) can usually be merged without issues.

Does the merged PDF keep bookmarks and links?

Yes. Internal links, bookmarks, and table-of-contents entries from each source PDF are carried over into the merged document so navigation still works.

Is my data secure during the merge?

All files are uploaded over an encrypted HTTPS connection. Processing happens on our server and files are automatically deleted after the merge completes. We never access, store, or share your documents.

What file formats can I merge?

This tool accepts PDF files only. If you need to combine images or Word documents into a PDF, convert them to PDF first using our converter tools, then merge the resulting PDFs here.
