Why Convert PDF to HTML?
HTML is the web’s native format. By converting a PDF to HTML you can embed it inline on a site, link directly to a section, search the text from the page itself, and let users copy individual paragraphs — none of which work as cleanly with an embedded PDF viewer.
HTML is also more accessible (screen readers handle a real text-tree better than image-based PDFs) and considerably smaller for text-heavy documents.
How to Convert a PDF to HTML
- 1
Drop your PDF
Drag a .pdf file onto the drop zone above, or click to pick one from your file picker.
- 2
Pick a mode and format
Vector (SVG) keeps the document scalable and preserves embedded fonts. Bitmap is best for image-only PDFs. Single HTML or ZIP — both are self-contained.
- 3
Download or preview
Click Download to save, or Open in new tab to preview immediately. The converted HTML works offline in any browser.
Features
No Upload Required
Conversion runs entirely in your browser. Files never leave your device.
Vector Output
SVG mode preserves drawing primitives, gradients, and embedded fonts so the result stays sharp at any zoom.
Bitmap Output
Image-only PDFs and very complex pages render as PNG or JPEG, with selectable text overlaid.
Selectable Text
Copy and paste from the converted HTML; the text layer mirrors the PDF’s reading order.
Single File or ZIP
Save everything inline as one .html file, or as a ZIP with separate per-page SVGs and font files.
Free, No Signup
No account, no watermark, no file size limits.
Frequently Asked Questions
▶How does the PDF to HTML converter work?
It runs Mozilla’s pdf.js entirely in your browser to parse the PDF’s content stream, then translates each page’s drawing operators into either an SVG (vector mode) or a PNG/JPEG image (bitmap mode), wrapped in a self-contained HTML file. Embedded fonts are extracted as @font-face data URIs, so text stays selectable and copyable in the output.
▶Are my PDF files uploaded to a server?
No. Everything happens in your browser — the converter never sends your file anywhere. You can verify this by opening browser dev-tools and watching the network tab while you convert.
▶What’s the difference between vector and bitmap modes?
Vector mode emits an SVG per page, with the PDF’s drawing primitives (paths, text, gradients, images) translated to their SVG equivalents. The output stays sharp at any zoom level and uses the original embedded fonts.
Bitmap mode renders each page to a PNG or JPEG image. It’s simpler and produces smaller output files for image-heavy PDFs, but pixelates when zoomed. Text remains selectable via an invisible overlay.
▶Can I open the converted HTML in any browser?
Yes. The output is a self-contained .html file that works offline in Chrome, Firefox, Safari, or Edge — just double-click it. The ZIP variant unpacks to index.html plus an assets/ folder; open the HTML the same way.
▶Why are some pages rendered as bitmap when I selected vector?
Pages with more than 50,000 drawing operators (very dense engineering drawings, scanned-and-overlaid PDFs) auto-fall back to bitmap so the result stays openable in browsers. A 200,000-operator vector page would produce a 20 MB SVG that takes minutes to load.
▶Does this work with password-protected PDFs?
Not at the moment — the converter only handles PDFs that open without a password. Remove the password using your PDF viewer’s Save As / Export feature, then upload the unlocked copy.
▶Will hyperlinks in the PDF still work in the HTML?
External URL links are preserved as <a> overlays in the output. Internal page-jump links (table of contents anchors) aren’t yet wired up, but the page-indicator and Ctrl+F search let you navigate manually.
▶How big can my PDF be?
There’s no hard limit because nothing leaves your browser, but practical limits depend on your device’s memory. PDFs under 50 MB convert smoothly on any modern device. Larger engineering-drawing PDFs (100 MB+) work but may take a minute or two.
▶Why do some characters look wrong in the output?
A small fraction of PDFs use private-use-area glyph encoding with incomplete ToUnicode maps. Visually those render correctly (the embedded font has glyphs at the right codepoints), but copying the text may yield gibberish.
For most PDFs, both visual fidelity and text selection work correctly. If you hit a specific PDF where text is broken, share a sample with us.
