Merging runs locally via the pdf-lib library. Your documents never leave your device — no upload.
Page layouts, fonts, images and most form fields are kept intact. Encrypted PDFs are read-only supported (best-effort).
Combining PDFs is common for invoicing, contract packs, expense reports, legal submissions and e-books. Rather than email five attachments that the recipient has to reassemble, you ship one document where the order is already correct. Merged PDFs also bookmark and print more reliably than separate files.
Most free online PDF mergers upload your files to a remote server. That means sensitive documents (contracts, medical records, tax returns) temporarily sit on someone else's disk. omnikitbolt runs pdf-lib entirely in your browser tab — nothing ever leaves your machine.
Text, images, page layout and most form fields survive the merge cleanly. Document-level bookmarks from the source files are not always preserved (a limitation of client-side PDF libraries). Password-protected PDFs are loaded with encryption ignored, so the output is a plain merged PDF. Don't upload files you aren't authorized to unlock.
