HTML to PDF conversion renders an HTML document as a fixed-layout PDF file. This converter accepts HTML code typed or pasted directly into a built-in editor, .html or .htm files uploaded from your device, or .txt files containing valid HTML markup. The editor includes a live preview panel that updates in real time as you write or edit HTML, showing the exact PDF page layout before you download it. Inline CSS styles are rendered in the output. External stylesheet files and externally hosted images are not fetched. All processing runs in your browser using JavaScript — your HTML code and file content never leave your device.

How it works

How to Convert HTML to PDF

Three steps. Three input methods. Browser-based — no server round-trip.

  1. 01

    Step 1: Add Your HTML Content

    Choose one of three ways to add your HTML. Drop an .html, .htm, or .txt file onto the upload area; click the blank editor and type or paste HTML code directly (useful for code snippets, generated HTML, or content copied from a CMS); or click Start with Template to begin with a pre-built HTML structure and customise it.

  2. 02

    Step 2: Use the Live Preview and Set Page Size

    The live preview panel updates in real time as you edit the HTML. Review how content flows across pages, how tables render, where page breaks fall, and how styles are applied. Adjust your HTML until the preview matches your intended output. Select your page size — A4 is the default, with US Letter, Legal, A3, and other options available.

  3. 03

    Step 3: Download Your PDF

    Click the download button. The PDF is generated from the live preview and saved to your device. The output matches exactly what you saw in the preview. No watermark is added. No account is required. Your HTML code and any file content remain in your browser throughout — nothing is transmitted to a server at any point in the process.

Developer features

What This HTML to PDF Converter Includes

Live preview

The PDF rendering updates in real time as you type or edit HTML in the editor. You see the exact page layout — table rendering, text flow, page breaks — before clicking to download. Not available in html2pdf.ws, CloudConvert, Sejda, or web2pdfconvert.

Custom HTML editor

A built-in editor lets you type or paste HTML directly without uploading a file. Useful for developers working with HTML snippets, generated templates, or code fragments copied from a CMS or design tool. Not available in any of the comparison tools.

Files stay in browser

Processing runs in your browser using JavaScript. Your HTML code and any uploaded file content are never transmitted to a server. All four comparison tools send HTML to their servers for processing — browser-based conversion is the only option for proprietary templates or sensitive content.

HTML templates

Pre-built HTML templates provide a starting structure. Click Start with Template to load a template into the editor, then customise the HTML for your content. A blank editor is also available for starting from scratch.

Developer note — external resources

External CSS stylesheets (link tags) and externally hosted images are not fetched during browser-based conversion. To ensure correct rendering:

  • • Inline CSS rules into a <style> block in the HTML <head> section, or apply them as style= attributes on individual elements
  • • Embed images as base64 data URIs rather than referencing external file paths

What This HTML to PDF Converter Is Used For

  • Developer document generation. Developers generating invoices, reports, or certificates programmatically in HTML often need a quick way to test how the output renders as a PDF without setting up a server-side PDF library. The live preview editor lets you paste generated HTML directly and see the PDF layout instantly. Browser-based processing means the test HTML — which may contain real customer data from a development environment — never leaves your device.
  • Email template to PDF conversion. Marketing teams and developers who build HTML email templates often need a PDF version for print, archiving, or client approval. Pasting the email HTML into the editor and downloading the PDF is faster than setting up a headless browser or server-side rendering pipeline. Inline CSS support ensures email-style formatting is preserved.
  • Content and document creation from HTML. Technical writers, content teams, and educators working with HTML content — course notes, guides, technical documentation, reference materials — can paste their HTML into the editor and produce a formatted PDF document. The template option provides a pre-structured starting point for users who don't write HTML from scratch.
  • Sensitive or proprietary HTML. Legal teams, product teams, and agencies working with HTML containing unreleased designs, confidential business documents, or client-specific templates cannot use server-based tools that retain uploaded files. Browser-based conversion is the only option for this use case without deploying local software.
  • Quick prototyping and layout testing. Designers and developers testing how an HTML layout renders at different page sizes can use the live preview to iterate without downloading and reviewing repeated outputs. Change the HTML, see the preview update, adjust the page-size setting, and download when the layout is correct.

Frequently Asked Questions

How do I convert HTML to PDF for free?
Go to oneclickpdf.net/tools/html-to-pdf and either drop your HTML file onto the upload area, paste HTML code directly into the editor, or start from a template. The live preview shows the PDF rendering in real time as you type. Select your page size before converting. The conversion runs entirely in your browser — your HTML and file content never leave your device. No account or signup is required. The PDF is available to download immediately after processing.
Can I type or paste HTML directly instead of uploading a file?
Yes. The converter includes a custom HTML editor where you can type or paste HTML directly without uploading a file. The editor accepts raw HTML including inline styles, tables, headings, lists, links, and any valid HTML structure. A blank editor and pre-built templates are available as starting points. The live preview updates as you type, so you can see the PDF output before downloading. This editor is not available in html2pdf.ws, CloudConvert, Sejda, or web2pdfconvert.
Does the live preview show exactly what the PDF will look like?
Yes. The live preview renders the HTML content in real time and shows the PDF page layout as it will appear in the final output file. You can see how page breaks fall, how tables and text flow, and how inline styles are applied before downloading. This is the only tool in this comparison set that provides live preview during conversion. html2pdf.ws, CloudConvert, Sejda, and web2pdfconvert do not offer live preview of the PDF output before it is generated.
What HTML and CSS features are supported?
The converter supports standard HTML elements including headings, paragraphs, tables, lists, images, links, and divisions. Inline CSS styles applied directly to HTML elements are rendered in the output PDF. External stylesheets loaded via link tags are not fetched during browser-based conversion. If your HTML relies on external CSS files, copy the relevant CSS rules into a style block within the HTML head section or apply them as inline styles on individual elements before converting to ensure correct rendering.
Will my HTML code be uploaded to a server during conversion?
No. The converter runs inside your browser using JavaScript. Your HTML code and any file content are processed locally on your device and never transmitted to a server. html2pdf.ws, CloudConvert, Sejda, and web2pdfconvert all send your HTML or URL to their servers for processing. If your HTML contains confidential content — proprietary templates, sensitive client data, or internal document structure — browser-based conversion ensures that content does not leave your machine at any point during conversion.
What page size options are available for HTML to PDF conversion?
The converter offers standard page size options including A4, US Letter, Legal, and A3. Select the page size before downloading the PDF. The page size determines the dimensions of each page in the output and affects how content is laid out and where page breaks fall. CloudConvert and Sejda also offer page size options. html2pdf.ws and web2pdfconvert do not offer page size selection, making the output dimensions fixed regardless of the intended use of the PDF.
Can I use HTML templates to get started?
Yes. The converter includes pre-built HTML templates that provide a starting structure for common document types. Click Start with Template to select a template, then edit the HTML in the editor to add your content. Templates provide a correctly structured HTML document without writing the markup from scratch. You can also open the blank editor to start from an empty document if you prefer to write or paste your own HTML. None of the comparison tools — html2pdf.ws, CloudConvert, Sejda, or web2pdfconvert — include built-in templates.
What file formats can I upload to the HTML to PDF converter?
The converter accepts .html, .htm, and .txt files uploaded directly onto the tool. It also accepts HTML pasted directly into the built-in editor without any file upload. If your HTML document is saved as a .htm file from an older application, it is accepted. Plain text files can be uploaded and converted if they contain valid HTML markup. Files without HTML structure will render as plain text in the PDF output. No account is required for any of these input methods.
Can I convert an HTML document that uses external stylesheets?
The converter processes HTML with inline styles but does not fetch external resources such as CSS files loaded via link tags or images hosted on external servers. If your HTML links to an external stylesheet, those styles will not be applied in the output PDF. To ensure correct rendering, copy the CSS rules you need into a style block in the HTML head section or apply them as inline styles on individual elements before converting. Images referenced via relative file paths also need to be embedded as base64 data URIs.
Can I convert HTML to PDF on a phone or tablet?
Yes. The converter works in any modern mobile browser, including Safari on iPhone and iPad and Chrome on Android. Open the page in your mobile browser, tap the upload area to select an HTML file, or use the built-in editor to paste HTML directly. The conversion runs in your browser without any app installation required. The PDF is available to download immediately and opens in any mobile PDF viewer or sharing application on your device.
