PDF to HTML
Convert PDF pages into a simple, readable HTML file for web viewing. Text is rebuilt into paragraphs and headings. All processing happens in your browser. Your files never upload anywhere.
Honest note: complex layouts, tables, and images are approximated, not reproduced pixel-perfect. Images are not included in the output. Best results come from text-based PDFs, not scans.
How to Convert a PDF to HTML
PDFs are great for printing and terrible for the web: text cannot be restyled, pages do not reflow on phones, and search engines struggle with them. Converting a PDF to HTML gives you a real web page you can edit, publish, or restyle. This tool does the conversion locally in your browser, rebuilding the document structure from the text positions inside the PDF.
Choose your PDF with the file picker. It stays on your device the entire time; nothing is uploaded.
Click Convert to HTML. The tool extracts the text of every page, groups it into lines and paragraphs, and detects headings from font sizes.
Preview the result below, then download the standalone .html file or copy the markup straight into your editor or CMS.
How the Converter Rebuilds Your Document
A PDF does not store paragraphs or headings; it stores individual text fragments with coordinates. The converter sorts those fragments by their vertical position, groups fragments on the same baseline into lines, and merges lines that sit close together into paragraphs. Then it looks at font sizes across the whole document: the median size is treated as body text, lines at least 50 percent larger become headings, and lines at least 25 percent larger become subheadings. Each PDF page becomes its own labeled section in the output, separated by a horizontal rule, so long documents stay navigable.
Honest Limitations
This is a readability converter, not a pixel-perfect replica. Multi-column layouts are flattened into a single column, tables become plain text lines, and footnotes, sidebars, and pull quotes lose their special positioning. Images are not carried into the HTML at all. Decorative text like page numbers and running headers is included as ordinary paragraphs, so you may want to delete those while editing. For clean source documents, such as reports exported from Word or Google Docs, the output is usually very close to the original reading order.
Tips for the Best Conversion
Text-based PDFs convert far better than scans; if your PDF is scanned images, run it through OCR first. Documents with a clear size hierarchy between headings and body text get the most accurate heading detection. After downloading, open the file in a text editor and do a quick pass: fix any missed headings, delete repeated headers and footers, and reinsert key images with the files from the Extract Images from PDF tool. The generated HTML uses simple inline CSS, so dropping it into WordPress or any CMS takes seconds.
Frequently Asked Questions
How does the PDF to HTML conversion work?
The tool reads your PDF with the pdf.js library and pulls out every piece of text along with its position and font size on the page. It then groups text fragments that sit on the same line into lines, merges close lines into paragraphs, and promotes unusually large text to headings. The result is assembled into a single standalone HTML file with simple built-in styling, which you can preview on this page and download. The whole process runs in your browser, so nothing is uploaded.
How are headings detected?
The converter measures the font size of every line in the document and finds the median, which is usually the body text size. Lines set at least 50 percent larger than that median become second-level headings, and lines at least 25 percent larger become third-level headings. This heuristic works well for reports, articles, and ebooks with a consistent typographic hierarchy. Documents where headings are the same size as body text, distinguished only by bold or color, will convert as plain paragraphs instead.
Are images included in the HTML output?
No, and this is stated clearly so you are not surprised. The current version converts text content only; photos, charts, and graphics from the PDF are not embedded in the HTML file. Complex layouts like multi-column pages, tables, sidebars, and footnotes are approximated into a single reading column rather than reproduced pixel-perfect. If you need the images too, use the Extract Images from PDF tool to pull them out separately.
Will this work on a scanned PDF?
Not directly. A scanned PDF contains pictures of pages rather than real text, so there is no text layer for the converter to read and the output would be empty. Run the scan through the OCR PDF tool first, which adds recognized text, and then convert the result to HTML. Native PDFs exported from Word, Google Docs, InDesign, or a browser print dialog convert the best because their text is clean and well structured.
Is my PDF uploaded to a server during conversion?
Never. The entire conversion happens inside your web browser using the pdf.js JavaScript library. Your file is read into local memory, processed on your device, and the HTML is generated locally for download. No document content is transmitted anywhere, which makes the tool safe for contracts, manuscripts, resumes, and other private material. After the page loads you could even go offline and the conversion would still work.
Can I edit the HTML file afterward?
Yes, that is one of the main reasons to convert. The downloaded file is plain, standards-based HTML with simple inline CSS, so it opens in any text editor, WordPress block editor, or web design tool. You can restyle it, fix any heading the heuristic missed, add the extracted images back in, or paste it into a content management system. Each page of the PDF becomes its own labeled section separated by a horizontal rule, which makes long documents easy to navigate while editing.
