Question 1

How does Convert PDF to HTML work?

Accepted Answer

The tool reads your PDF inside the browser using PDF.js, extracts the text content stream along with structural cues (headings, paragraphs, links), and writes a standalone HTML file with the layout preserved. The processing happens entirely in your browser — nothing is uploaded to a server.

Question 2

Are my files uploaded anywhere?

Accepted Answer

No. Convert PDF to HTML runs entirely in your browser using WebAssembly and JavaScript. Your files never leave your device. You can confirm this by opening DevTools, switching to the Network panel, and watching the conversion run with zero outbound requests.

Question 3

Will the HTML preserve the PDF's exact layout?

Accepted Answer

For text-heavy PDFs (reports, academic papers, articles), yes — headings, paragraphs, ordered lists, and links round-trip cleanly. Image-heavy or complex multi-column magazine layouts convert with mixed results because the PDF-to-HTML problem itself does not have a perfect general solution. The output is suitable for web archiving and accessibility workflows where readable text matters more than pixel-perfect layout.

Question 4

Is there a file size limit?

Accepted Answer

Soft limit of 100 MB per file for browser memory reasons. Larger files may work but can slow down older devices. For very large PDFs, split first using /split and convert each part separately.
