Printing and PDF guides

72 guides across 18 topics on printing web pages without ads and working with PDF files in the browser.

Printing web pages

To print a web page without ads, open it in a printer-friendly tool or your browser Reader mode first, then print. This removes navigation, ads and sidebars and typically cuts a nine-page printout to two or three pages while keeping the article text and images intact.

Saving web pages as PDF

Press Ctrl+P (Cmd+P on Mac), change the destination to "Save as PDF" and click Save. On iPhone, use the Share sheet, tap Options and choose PDF. Both keep the text selectable and the links clickable, unlike a screenshot, which stores pixels only.

Merging PDF files

Add every PDF to a merge tool, drag the files into the order you want, then merge and download one combined file. Pages keep their internal order within each file, so the file list decides everything. A browser-based merge runs locally, so nothing is uploaded to a server.

Splitting and extracting PDF pages

Open the PDF in a split tool and choose a mode: single pages, custom ranges such as 1-3,5,8-, or every N pages. Extracting keeps the chosen pages in one new file; splitting produces several files. The original on your disk is never modified by any of them.

Compressing PDF files

Compress a PDF by choosing between two methods. Lossless structural compression subsets fonts and removes unused objects, typically saving 10-30 percent with zero visible change. Image downsampling re-encodes embedded photos at a lower DPI, which can cut a scanned document by 80-95 percent but is not reversible.

Converting PDF to other formats

Converting out of PDF works best when the file has a real text layer and a simple layout. Word and Google Docs both open PDFs directly and rebuild the text well. Tables need column detection or Power Query. Scanned PDFs must be OCR-ed first, and slide conversion needs Acrobat or a desktop app.

Converting files to PDF

Every major application exports PDF directly: Word uses File → Save As → PDF, Excel uses Export → Create PDF/XPS after setting a print area, browsers use Ctrl+P with "Save as PDF" as the destination, and images can be combined into a single PDF. The settings that matter are font embedding, scale-to-fit and DPI.

PDFs and images

To turn a PDF page into an image, render it at a chosen resolution: 144 DPI for screens, 300 DPI for printing. To recover a photo that was placed in the PDF, extract the embedded image instead, which returns the original pixels without re-rendering or quality loss.

Signing PDFs

To sign a PDF without printing it, open the file in a signing tool, create a signature by drawing, typing or uploading a transparent PNG, drag it onto the signature line, add the date, then flatten and download. In most countries this carries the same legal weight as ink on paper.

OCR and scanned documents

OCR converts the pixels of a scanned page into machine-readable characters and stores them as an invisible text layer aligned with the image. The page still looks identical, but it becomes searchable, selectable and copyable. Accuracy runs above 98 percent on clean 300 DPI print and far lower on handwriting.

Watermarks, page numbers and stamps

To mark a PDF, add a watermark for a visual warning, page numbers for navigation, and a header or footer for identifying details such as a company name or file reference. All three are drawn onto the existing pages, so they change how the file looks without changing the underlying text.

PDF privacy and security

Before sharing a PDF, strip the document metadata, redact any sensitive content properly by removing it rather than covering it, and use encryption only when you genuinely need to control who can open the file. Always verify redaction by trying to select and copy the text afterwards.

Printing recipes

To print a recipe cleanly, use the site's own Print Recipe button if the recipe sits in a recipe card, since it opens a stripped-down version. If there is no button, paste the page address into a printer-friendly tool, delete the story and the photos, and print the result as one page.

Students and research

Students save the most paper by printing academic PDFs two pages per sheet and double-sided, which turns a 24-page paper into six sheets. Annotate the PDF rather than the paper copy so highlights stay searchable, and record the author, title, date, URL and access date for every web source you cite.

For publishers and developers

Give readers a print button and a print stylesheet. The button is a plain HTML anchor or a button calling window.print(), placed near the article title. The stylesheet hides navigation, resets the layout to a single column, sets @page margins, controls page breaks and prints link URLs so the paper copy stands on its own.

Saving paper and ink

The four settings that matter most are duplex, greyscale, draft quality and pages per sheet. Applied together they typically cut the cost of a document by 70 to 90 percent. Set them as your printer defaults rather than per job, and use print preview and page ranges to avoid printing pages nobody reads.

QR codes for print

A printed QR code scans reliably when it is exported as vector, printed at least 2 cm wide, surrounded by a four-module quiet zone, and set in dark ink on a light background. Use the 10:1 rule: the code must be at least one tenth of the scanning distance.

Browser extensions and shortcuts

Firefox and Safari have built-in reader modes that produce clean printouts: press F9 in Firefox or Control-Command-R in Safari, then print. Chrome has no print-ready reader mode, so use a bookmarklet, an extension or a web-based cleaner. Bookmarklets need no permissions and work in every browser.
