How to Save a Web Page as a PDF
Saving a web page as PDF sounds like a one-button job, and for a simple article it is. What goes wrong is everything around the edges: navigation bars eating the page, adverts loading as blank rectangles, and text that reflows into a column two centimetres wide.
Three different jobs
- Keeping an article you want to read later. You want the text and images, not the menus.
- Recording evidence of what a page said on a date. You want the whole page as it appeared, including the URL and timestamp.
- Printing a form or a receipt. You want the exact layout, at the right paper size.
Save a page
- Open HTML to PDF and paste the URL, or paste the page HTML directly.
- Choose the page size: A4 for printing and filing, or "fit to content" for a screenshot-like result.
- Wait for images and fonts to load. A save that finishes in one second usually means the styles did not load.
- Check the first page first — that is where navigation bars and cookie banners appear.
Why the layout sometimes breaks
Web pages are responsive: they rearrange themselves to fit the screen and the paper. A PDF is a fixed page. The conversion has to pick a width and hope.
Print stylesheets usually fix this. Every well-built site has a `@media print` rule that hides navigation, removes background images, and switches to a readable serif typeface. If the site has one, the conversion uses it and the result looks like a document rather than a screenshot.
The other common cause is lazily loaded images. Pages that load images as you scroll produce a PDF with empty boxes if the conversion does not wait long enough.
Common problems
- Menu and footer on every page: the site has no print stylesheet. Remove them with Crop PDF after saving, or use reader mode in the browser first.
- Text in a thin column: the page was saved at a mobile width. Force desktop width and re-save.
- Blank rectangles where images should be: lazy loading. Re-save and wait longer, or scroll the page first.
- Fonts changed: the page used a web font that was blocked. Minor for reading, but note it if the page is evidence.
- The PDF is enormous: full-page background images. Compress it afterwards.
Saving a page as evidence
A PDF of a web page is weaker evidence than most people assume. It is trivial to edit, it has no timestamp that anyone verifies, and the page can change a minute later.
If the record matters, capture the URL and the date visibly — for example by including the browser address bar in the capture — and keep the original HTML alongside it. Better still, use a service that archives pages with a signed timestamp.
For everyday purposes — a receipt, a cancellation notice, a booking confirmation — a plain PDF is fine and far better than nothing.
Privacy
Pasting a URL into an online converter sends that URL to somebody else's server, and they may keep a copy of the rendered page. For a page behind a login, that means your session content.
A browser-based converter renders the page locally. If the page is one you are logged into, nothing is sent anywhere.
