How do I convert PDF to HTML?

Add your PDF file to the upload area above, then press Convert. The HTML file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to HTML reduce quality?

The result is a reconstruction rather than a perfect copy. It is genuinely useful for reading and reuse, but review it before relying on it for anything important.

How large a file can I convert?

Up to 100 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

PDF and HTML explained

PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.

HTML is the markup language of the web, describing document structure — headings, paragraphs, lists, links — which browsers then render.

Where PDF files come from: Contracts, invoices, reports, forms, academic papers and scanned documents.
Where HTML is used: Web pages, email templates and exports from documentation tools.

PDF vs HTML

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

PDF compared with HTML
Property	Source	Target
Compression	Lossy or lossless	None
Introduced	1993	1993
Browser support	Universal.	Every browser.

PDF is stronger at: Looks identical on every device, in every viewer, when printed. Supports digital signatures, forms and embedded fonts. Universally readable without special software.
HTML is stronger at: Renders in every browser. Semantic structure aids accessibility and search engines. Styleable with CSS.

Why convert PDF to HTML?

People make this switch when they run into the limits of PDF: the document still needs collaborative editing. HTML is the better fit when publishing on the web or generating documents programmatically.

PDF limitations that prompt the switch: Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run. Can be large when it contains high-resolution images.
What you give up: Layout depends on the renderer and available fonts. Not a fixed-layout format.

What is preserved when converting PDF to HTML?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

A PDF full of scanned pages is a stack of pictures, not a document. Selecting text is impossible until OCR has been run over it.

About these formats

Source

Portable Document Format

Fixed-layout documents that look identical everywhere.

Extensions: .pdf
MIME type: application/pdf
Best for: Sharing documents · Printing · Contracts and forms
Compatibility: Universal.

Target

HyperText Markup Language

The markup language of the web.

Extensions: .html, .htm, .xhtml
MIME type: text/html
Best for: Web pages · Email templates · Rich exports
Compatibility: Every browser.

PDF stores positioned glyphs, not paragraphs. FileTools360 reconstructs headings, paragraphs and reading order from the text layer — it works well for straightforward documents and poorly for multi-column layouts, forms and scans. Scanned pages have no text layer at all; run OCR first.
