How to merge PDFs
- Choose or drop PDFs, then add more if needed (2–10 files in total).
- Review first-page previews and page counts. Drag documents into order, or use Move earlier and Move later. Inspect any original page, remove unwanted files or restore upload order. Undo restores the last document change.
- Select Merge PDFs, then download and review the combined document.
Example
A two-page report followed by a one-page appendix produces a three-page PDF. Change their order to place the appendix first. Page sizes and existing page rotations are retained.
Privacy and limitations
Files remain in your browser and are processed in a worker. Total input is limited to 20 MB and 100 pages. Cancel stops the current operation and preserves accepted documents; Clear all PDFs removes them; preview preparation and merging each have a 30-second timeout. No cloud fallback or OCR is used.
Encrypted PDFs and PDFs containing interactive forms or signature fields are rejected. Page content is copied without rasterizing it, but document-level bookmarks, attachments, metadata and other advanced structures may not transfer. This tool is not a PDF sanitizer; review documents from untrusted sources and verify the output before relying on it.
Will all my PDF features survive?
The tool is for plain page-based documents. It does not promise to preserve every PDF feature or a digital signature. Keep your originals.
