Merge PDF
Free, private PDF merger. Combine multiple PDF files into one document in your browser — reorder files, then download a single merged PDF. No signup, no uploads, no watermark.
Bolta writes your posts in your brand voice, automatically — and waits for your approval before posting.
You just used the Merge PDF. That was one output. Bolta does this every day, on schedule.
Bolta vs typical online PDF mergers
Most mergers upload your documents, cap the number of files, or watermark the result.

|---|---|---|

| Files | Often capped or paywalled | As many as you like, free |
| Watermark | Some add their logo | Never |
| After merging | File just sits there | Plan & publish in Bolta |
