About bopdf

Privacy first: no uploads, no file storage, no accounts.
Honest results: we show real file sizes and explain trade-offs, such as compression turning pages into images.
Free: the tools are free to use. In the future we may display advertising to cover hosting costs.

bopdf is a small independent project with one simple idea: you shouldn’t have to upload private documents to a stranger’s server just to merge or sign a PDF.

Modern browsers are powerful enough to edit PDFs locally. bopdf packages proven open-source libraries — pdf-lib (MIT) and Mozilla pdf.js (Apache 2.0) — into easy tools available in 13 languages, from English and Chinese to Hindi, Arabic and Bengali.
