A PDF is a poor thing to publish on the web: it downloads instead of opening, it does not reflow on a phone, and search engines index it grudgingly. Converting it properly means recovering the structure the layout implies, not wrapping every line in a div. This tool groups text runs into lines, lines into paragraphs, and promotes the larger lines to headings, then writes markup that says what each block is. You can take a complete page — responsive, with a light and dark palette built in — or just the body fragment to drop into an existing template, with an id on each page break so you can link into the document.
Features
Semantic markup: h1 to h6, p, ul, li, blockquote, pre and table
Wrapped lines rejoined into real paragraphs rather than one line each
Full standalone page, or a body fragment for your own template
The full page is responsive and respects the reader's light or dark setting
Optional id on each page break so you can deep-link into the document
Rendered preview beside the markup, in a sandboxed frame
Copy to the clipboard or download the .html file
How to use the PDF to HTML
Drop the PDF onto the page
Choose a full page or a body fragment
Read the rendered preview to check the structure came through
Heading levels come from the type size relative to the body text on each page.
Common errors & troubleshooting
The markup is empty. — The PDF holds no text layer. Recognise the text first, then convert the searchable version.
Images from the PDF are missing. — Only text is converted. Export the pages as images separately and reference them from the markup where they belong.
Headings are all the same level. — The document sets every heading at the same size, so there is nothing to distinguish level 2 from level 3. Adjust the levels by hand once in the markup.
Page furniture appears throughout the document. — Running heads and folios are ordinary text in a PDF. Strip them with a find-and-replace pass over the generated markup.
Frequently asked questions
Does converting to HTML upload my PDF?
No. The text layer is read and the markup is generated in this tab, so an internal handbook or a client report never leaves your device.
Will the HTML look like the original PDF?
No — it is built to read well on a screen, which means one column, a comfortable measure and a responsive layout. The content is the same; the design is not.
Which output should I use for a CMS?
The body fragment. It carries no head, no styling and no wrapper, so it slots into an existing template without fighting it.
Is the generated page accessible?
It uses real headings, lists and table headers, which is most of what a screen reader needs. Check the heading order and add image descriptions if you add images.
Can I convert several PDFs into one page?
Merge the PDFs first, then convert once — that keeps the heading hierarchy consistent across the whole document.
