HTML to PDF Converter

Turn HTML files into PDF in a couple of clicks. HTML is the markup language of the web; PDF is a fixed-layout document format that looks identical everywhere. Content is preserved and the layout is rebuilt for the target format.

How to use it

  1. 1

    Add your HTML files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    The defaults suit most people. Open Advanced to control page size, typeface and margins.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your HTML file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your HTML file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

A Word file is usually a draft — which means it carries the things that were not meant to be final, and often tracked changes and comments nobody removed. It matters more than it sounds, because of what documents usually are:

Tenancy and loan agreements

identity details plus your financial position

Medical and clinical reports

patient information that is regulated in most countries

Unpublished manuscripts

work whose value depends on it not circulating

Employment contracts

salary, notice periods, restraint clauses

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

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.

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?

The content survives; the layout is rebuilt. Text and the order it is read in carry across, but PDF lays the page out again rather than reproducing HTML's exact positioning, so line breaks, page breaks and spacing will differ. Anything that depends on precise placement is worth checking in the result.

Measured, not estimated

What converting HTML to PDF actually costs

On every sample measured, the PDF came out larger — 131× larger at best and 154× larger at worst.

Each row is one sample chosen to isolate a property these formats treat differently.

Produced by this site's own converter. The same code that runs in your browser, at the same default settings, so these are the bytes you would download.

Samples are generated from a fixed seed rather than taken from real photographs or documents, so the corpus is reproducible and carries no licensing question — and so the numbers predict the shape of your result rather than its exact size.

Good to know

HTML to PDF Converter — questions

How do I convert HTML to PDF?

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

Is it safe to convert HTML files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your HTML file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential HTML files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

What should I know before converting HTML to PDF?

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.

What is preserved when converting to PDF?

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. Pick the file through your phone's file picker — Files on iOS, or Downloads on Android — including files stored in iCloud or Google Drive.
