Merge PDF Files Online

Drag to reorder and combine any number of PDFs - no watermark, no limits

Combine multiple contracts, thesis chapters, or scanned pages into a single PDF: add any number of files at once, drag to set the order, and merge with one click - no watermark, no page or usage limits.

All merging happens locally in your browser: no queuing on a server, no privacy worries for confidential files, and merge speed depends only on your machine.

Download the merged file directly, or continue in the editor - a long merged document really benefits from a bookmark outline, which you can add right here, along with compression or watermarking.

How to use

FAQ

Are there limits on file count or size?

No hard limits. Since processing is local, capacity depends on your device memory - hundreds of MB is usually fine.

Are the original bookmarks kept?

Yes. Each file’s bookmark outline is migrated into the merged PDF with page numbers shifted automatically, and you can optionally group them under a top-level bookmark per file - something most online mergers cannot do.

Does it add a watermark?

No. The tool is completely free and the output carries no watermark or branding.

Can I merge password-protected PDFs?

Unlock them first with the "Unlock PDF" tool, then merge.
