How do I convert HTML to PDF?

Add your HTML file to the upload area above, then press Convert. The PDF 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 PDF reduce quality?

Text, structure and images carry over faithfully. Exact page layout does not, because PDF lays content out differently from HTML. Check headings, tables and page breaks in the result.

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.

HTML and PDF explained

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

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.

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

HTML vs PDF

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

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

HTML is stronger at: Renders in every browser. Semantic structure aids accessibility and search engines. Styleable with CSS.
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.

Why convert HTML to PDF?

People make this switch when they run into the limits of HTML: you need a self-contained, fixed-layout file to send someone. PDF is the better fit when sharing a finished document where the layout must not move.

HTML limitations that prompt the switch: Layout depends on the renderer and available fonts. Not a fixed-layout format. Requires separate assets for images.
What you give up: Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run.

What is preserved when converting HTML to PDF?

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

HyperText Markup Language

The markup language of the web.

Extensions: .pdf

Best for: Sharing documents · Printing · Contracts and forms
Compatibility: Universal.

The page is rendered by your own browser, so it looks the way it does on screen — CSS, colours, tables and all. Nothing is fetched from other websites, so a page whose stylesheet or images live elsewhere converts without them; save it as a complete page first. Switch to text-only in the settings if you would rather have a small file with selectable text.
