Pretty PDF vs Online URL-to-PDF Converters

Searching "URL to PDF" brings up dozens of free online converters -- paste a URL, click convert, download a PDF. They work in a pinch, but the output quality, privacy implications, and limitations become obvious fast. Here's how Pretty PDF compares to these online tools.

Free -- 3 PDFs per month. No watermarks, ever.

The privacy problem

Online converters require you to paste your URL into a third-party website. That server fetches the page, processes it, and stores the result -- at least temporarily. For authenticated or internal pages, this is a non-starter. For any page, you're trusting an unknown service with your browsing activity.

Consider what happens when you paste a URL: the converter's server makes a request to that page from its own IP address. If the page is public, the converter now has a copy of the content and knows what you're reading. If the page requires authentication, the converter simply can't access it -- you'll get a PDF of a login screen or an error page. And even for public pages, many converters retain the generated PDF on their servers for caching purposes, meaning your content sits on infrastructure you don't control.

Pretty PDF's extension captures the page locally in your browser, then sends it to your own authenticated account on Pretty PDF's server. The content is processed in the context of your account, stored in your personal library (if you choose), and never shared with or visible to other users. Because the extension runs in your browser, it also works with any page you're logged into -- private repos, internal wikis, authenticated dashboards -- without exposing your credentials to a third party.

The quality difference

Online converters use basic HTML rendering -- often wkhtmltopdf or a headless Chrome instance -- to convert the page. The output looks like a browser screenshot dumped into a PDF. No content extraction, no template styling, no professional fonts. Headers, footers, sidebars, ads, and cookie banners all end up in the document. Tables overflow the page margins, code blocks get cut off, and images may be missing entirely if they rely on lazy loading or JavaScript.

Pretty PDF uses WeasyPrint -- a CSS paged media engine purpose-built for document generation. WeasyPrint handles proper page breaks, orphan and widow control, and CSS paged media properties correctly. The result is a document that reads like a professionally typeset PDF, not a web page crammed into a page boundary.

On top of the rendering engine, Pretty PDF applies professional templates with embedded fonts -- Fraunces for headings, Instrument Sans for body text, and JetBrains Mono for code blocks. These fonts are embedded directly into the PDF, so the document looks the same on every device and operating system. Online converters use whatever system fonts are available on their server, which often means Times New Roman or Arial -- hardly a professional look.

Pretty PDF's content extraction also makes a significant difference to quality. Instead of converting the entire page, Pretty PDF's engine identifies the main content area and discards everything else. For eight major platforms -- GitHub, Notion, Medium, Stack Overflow, Dev.to, Substack, Reddit, and Confluence -- dedicated parsers understand each site's unique HTML structure and extract content with even higher precision. The output is a focused, well-structured document rather than a noisy page dump.

When online converters make sense

To be fair, online converters aren't always the wrong choice. There are scenarios where pasting a URL into a free converter is perfectly reasonable:

  • You're on someone else's computer -- If you can't install a Chrome extension (a shared workstation, a public computer, a locked-down corporate machine), an online converter is your only option for a quick conversion.
  • You need a one-off conversion and don't care about quality -- If you just need a rough PDF for internal reference and formatting doesn't matter, a free online converter gets the job done in seconds.
  • You're converting a public URL with no privacy concerns -- If the page is entirely public and you don't mind a third-party server accessing it, the privacy trade-off is minimal.
  • You need a quick screenshot-style PDF -- If you want a full-page capture that preserves the exact visual layout including navigation and sidebars, an online converter's "full page dump" approach is actually what you want.

For everything else -- when you care about output quality, need to convert authenticated pages, want professional styling, or convert pages regularly -- Pretty PDF produces dramatically better results with none of the privacy trade-offs.

Frequently asked questions

It depends on the service. When you paste a URL into an online converter, that server fetches the page, processes it, and stores the result -- at least temporarily. You're trusting an unknown third party with your browsing activity and potentially with the content of the page. For public pages this may be acceptable, but for anything behind a login, anything containing sensitive data, or any internal company page, it's a significant privacy risk. Pretty PDF's Chrome extension captures the page locally in your browser and sends it to your own authenticated account, so the content never passes through an unknown third party.
Most online PDF converters operate on a freemium model. They offer free conversions to attract users but add watermarks (logos, text overlays, or branding) to the output to encourage upgrades to a paid plan. Some also limit the number of free conversions per day or degrade the output quality on the free tier. Pretty PDF never adds watermarks to any PDF on any tier -- free or paid. The free tier gives you 3 PDFs per month with full quality and all 5 templates.
Most online converters struggle with JavaScript-heavy sites. Many use basic server-side fetching (similar to curl or wget) that downloads the raw HTML without executing JavaScript. This means single-page applications, dynamically loaded content, lazy-loaded images, and interactive elements simply won't appear in the PDF. Some premium converters use headless Chrome, which is better but still misses content that requires user interaction or authentication. Pretty PDF's Chrome extension captures the fully rendered DOM from your actual browser session, including all JavaScript-rendered content, expanded toggles, and authenticated content.
Pretty PDF has a free tier that gives you 3 PDFs per month with all 5 templates, full content extraction, and no watermarks -- no credit card required. Unlike most online converters, there are no quality limitations on the free tier. Pro starts at $5/month for 50 PDFs, custom branding, and print profiles. Pro+ is $12/month for unlimited PDFs, 25 GB cloud storage, and API access. See the pricing page for full details.
No. Online converters fetch the URL from their own servers, which means they have no access to your login sessions, cookies, or authentication tokens. If you paste a URL to a page that requires login -- such as a Notion workspace, a private GitHub repo, or an internal Confluence wiki -- the converter will either get a login page or an access denied error. Pretty PDF's Chrome extension captures the page directly from your browser where you're already logged in, so it works with any authenticated content you can see.
