Affiliate & Advertising Disclosure
Transparency matters. This page explains how PDFzen can make money — and the rules we follow so our guides stay honest and useful.
Our tools are free and always will be
Every PDF tool on PDFzen runs inside your own browser. We do not charge for merging, compressing, converting, or editing, and we do not upload your files to any server. That part is and stays free.
Advertising
This site may display contextual ads (for example, through Google AdSense). These ads are placed automatically based on the page content and your general region; we do not choose the specific advertisers, and ad networks may use cookies as described in our Privacy Policy.
Affiliate links
Some pages may contain affiliate links to paid software or services we mention (such as desktop PDF editors or cloud converters). If you click one of those links and later buy, we may earn a commission — at no extra cost to you. Affiliate relationships never affect whether or how a tool appears in our guides.
We never take payment to rank a tool
Our recommendations are based on what we actually tested in the browser — speed, privacy (no upload), output quality, and price. We do not accept money to put one product above another, and our comparison and "best-of" pages are not sponsored. If that ever changes, this page will say so.
How to tell an affiliate link
Where an affiliate link is used, we mark it with a short note such as "affiliate link" near the recommendation. Plain editorial links to a vendor's site without a commission are not marked.
