Why Markdown
Markdown keeps the structure of a document while staying plain text, so it is the best format for note apps, static sites and AI chatbots that have limited context. bopdf joins broken lines into paragraphs, turns bullets into - lists and separates pages with ---.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
Are tables converted?
Tables become text lines. For spreadsheet data use PDF to Excel.
Is the PDF uploaded to an AI service?
No. Conversion happens locally in your browser; nothing is sent anywhere.
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.
