PDF and document tools that keep your files on your device the entire time — no upload, no third-party server processing your contracts, IDs, or scanned paperwork.
Anyone merging, splitting, or trimming PDFs who'd rather not upload a sensitive document to an unfamiliar website.
Yes — PDF merging, splitting, and page removal happen entirely in your browser using client-side libraries. Your files are never uploaded to a server, which is worth checking on any tool handling sensitive documents, not just this one.
Very large PDFs (100+ MB) may be slow since your device's memory is doing the processing rather than a server's. Most everyday documents process in a few seconds.
No — these operations rearrange existing pages rather than re-rendering them, so there's no quality loss or recompression involved.
