Cookie Policy
Last updated: October 31, 2026
This Cookie Policy explains what cookies and similar technologies are, which ones smartpdfconvert.com uses, and how you can control them. Read it together with our Privacy Policy.
1. What are cookies?
Cookies are small text files that a website saves on your device. Similar technologies include local storage, which keeps information inside your browser. They help a site remember you between pages and visits, measure how it is used and show relevant advertising. Your documents are never stored in cookies – files you open in our tools are processed on your device.

3. Google advertising cookies
Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to this website or other websites. Google’s use of advertising cookies (such as the DoubleClick cookie) enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet. You can opt out of personalised advertising in Google Ads Settings, or opt out of some third-party vendors at www.aboutads.info and www.youronlinechoices.eu. See how Google uses cookies in advertising.
4. Your consent
If you visit from the European Economic Area, the UK or Switzerland, a consent message asks for your permission before non-essential cookies and personalised ads are used. Essential cookies do not need consent because the site cannot work without them. You can change or withdraw your consent at any time from the privacy link in the message or by clearing cookies for this site.
5. How to manage cookies
- Browser settings: every browser lets you see, block and delete cookies – look for “Cookies” or “Site data” under Privacy in Chrome, Edge, Firefox or Safari.
- Ads: use Google Ads Settings or the opt-out pages above.
- Analytics: install the Google Analytics opt-out add-on.
- Language: choose English with the 🌐 button to switch translation off.
Most tools keep working without cookies. Blocking essential cookies will stop you from signing in, and blocking advertising cookies does not remove ads – it only makes them less relevant.
6. Changes
We may update this policy when we add tools or services. The date at the top shows the latest version.
