How to Merge PDF Files Online for Free

Combine multiple PDF documents into one file instantly in your browser. No upload, no signup — 100% private.

Merging PDF files is one of the most common document tasks — combining invoices, reports, or contracts into a single file for easier sharing and archiving.

ConvertCraft's PDF Merge tool runs entirely in your browser using WebAssembly. Your documents are never uploaded to any server, making it ideal for sensitive business documents.

To merge PDFs, open the tool, drag and drop your files in the desired order, and click Merge. You can reorder pages by dragging them in the preview panel.

The tool preserves all formatting, fonts, images, and bookmarks from the original PDFs. There is no file size limit beyond your browser's available memory.

Works on Chrome, Firefox, Edge, and Safari on both desktop and mobile. No plugins or installations required.

Frequently Asked Questions

How many PDFs can I merge at once?

There is no hard limit. You can merge dozens of files — the only constraint is your browser's available memory. Most users can handle 50+ files without issue.

Does merging PDFs reduce quality?

No. ConvertCraft's merge tool combines pages losslessly — all text, images, fonts, and vector graphics are preserved exactly as they appear in the originals.

Can I reorder pages before merging?

Yes. After adding your files, you can drag and drop individual pages to rearrange them before clicking Merge.
