关于这个工具
Drop two or more PDFs, reorder them with up / down buttons, and download a single merged PDF. The merge runs entirely in your browser using pdf-lib — your documents never leave your device.
Common cases: combine scanned pages into one report, stitch chapters into a single ebook, batch contracts into one signing pack.

常见问题
- Does my PDF get uploaded?
- No. Merging happens entirely in your browser using pdf-lib. Your files never leave your device.
- How many PDFs can I merge at once?
- There's no hard limit, but very large totals (>500MB combined) may run into browser memory limits.
- Are bookmarks, links, and form fields preserved?
- Page content (text, images, vector graphics) is preserved exactly. Document-level metadata (outlines, named destinations) and form fields can be partially preserved depending on the source PDFs.
- Can I reorder pages within a PDF, not just merge whole files?
- v1 merges whole files in the order you list them. For per-page reordering or extraction, use the PDF Split tool to break a PDF into individual pages first, then re-merge.
