Lossless Merging
Pages get copied byte-for-byte from your originals into the new file - same text, same images, same fonts, same quality. Nothing gets re-rendered or re-compressed.
Drag to Reorder
Got the order wrong? Drag PDFs up and down, or use the arrow buttons. Remove individual files with one click before you merge.
Text Stays Searchable
Unlike "image-based" PDF tools, your merged PDF keeps its selectable text, working hyperlinks, and proper bookmarks. Search and copy still work.
Smart Validation
Each PDF gets validated as you drop it. Password-protected or corrupt files are flagged immediately so you know which ones won't work.
Up to 50 PDFs
Combine large batches in one go - quarterly reports, scanned chapters, contract bundles. Tested up to 50 files at once on standard hardware.
100% Private
Merging happens entirely in your browser using pdf-lib. Your files never get uploaded - safe for legal documents, medical records, or anything sensitive.

FAQ

COMMON QUESTIONS

Yes. This is a real merge - pages get copied as-is from each source PDF into the combined document. Selectable text stays selectable, hyperlinks keep working, and quality is identical to the originals. No re-rendering, no compression artifacts.

Up to 50 files per merge, with each file capped at 100 MB. For larger jobs, do it in batches and merge the resulting batch outputs together. Your browser's memory is the real bottleneck - 5-10 typical PDFs work instantly even on phones.

Password-protected PDFs can't be merged - the tool flags them immediately so you can see which files have a problem. Remove the password first using a PDF tool like Adobe Acrobat (or your operating system's print-to-PDF feature, which strips most protections), then come back here.

No. Merging happens entirely in your browser using the pdf-lib library. Your PDFs never leave your device. Safe for contracts, medical records, financial documents, and any sensitive material.

Each page keeps its own original size in the merged file - no scaling, no stretching. So a merged PDF can have A4 pages from one source and US Letter from another sitting side-by-side. PDF readers handle this natively.

Not in this tool - it merges all pages from each PDF in order. To extract specific pages first, use a "Split PDF" tool (coming to TPL Tools soon), then merge the resulting files here. For now, you'd need to remove unwanted pages from each PDF before merging.
