Why bopdf is different
Most online PDF sites upload your document to their servers, process it there and ask you to trust that it gets deleted afterwards. bopdf works the other way round: the whole PDF engine is downloaded to your browser once, and your files are processed locally on your own computer or phone. Contracts, bank statements, IDs, medical records — none of it ever travels across the internet.
Because nothing is uploaded, bopdf is also fast: there is no waiting for uploads and downloads, and big files are limited only by your device memory.
Built on trusted open-source libraries
bopdf uses pdf-lib (MIT license) to create and edit PDFs and Mozilla’s pdf.js (Apache 2.0 license) — the same engine that displays PDFs in Firefox — to render pages. Both are served from our own domain; no third-party code touches your documents.
Free, with no catch
All tools are free with no account, no daily task limits and no watermarks stamped on your output. The site may show unobtrusive ads in the future to cover costs — ads never have access to your files, because your files are never on our servers.
Frequently asked questions
Is bopdf really free?
Yes. All tools are free to use with no sign-up, no daily limits and no watermarks added to your files.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
Does it work on iPhone and Android?
Yes. bopdf works in modern browsers on Windows, macOS, Linux, iOS and Android — no app to install.
