Privacy Policy
Last updated 15 August 2026
This policy explains how MicroPDF (“we”, “us”), a service of Black Diamond Studios, handles the files you process, the cookies we use, and the advertising shown on the site.
1. The files you process
Most of our tools run in your browser: the file is read into your browser’s memory, processed on your own device, and offered back to you as a download.
Some tools require software that cannot run in a browser and therefore process your file on our server. These are: PowerPoint → PDF, PDF → Word, OCR PDF, Repair PDF, PDF/A, and Optimize for Web. For these tools your file is sent to us over an encrypted connection and processed in an isolated environment. We handle those uploads as follows:
- The file is used only to perform the conversion you requested.
- It is held only for the moment it takes to process, then deleted — it is not retained, backed up, or used for any other purpose.
- Each server tool’s page is labeled so you know when a file will be uploaded.
2. Cookies and similar technologies
We use cookies and similar technologies for essential site functionality (for example, remembering your light/dark theme preference), to understand how the site is used, and to deliver and measure advertising. You can control cookies through your browser settings and through the advertising choices described below.
3. Advertising
This site is supported by advertising. We work with third-party advertising partners who may use cookies, device identifiers, and similar technologies to show ads, including ads based on your prior visits to this and other websites, and to measure how ads perform. These partners collect and process data under their own privacy policies, which we do not control.
You can opt out of personalized advertising through your device or browser settings and through industry tools such as Your Online Choices (EU), the DAA opt-out (US), and Google’s Ads Settings.
4. Analytics
We may use analytics services to understand aggregate usage of the site (such as which tools are popular and how pages perform) so we can improve them. This data is used in aggregate and not to identify you.
5. Accounts
You can use the tools without creating an account. If we introduce accounts or paid plans in the future, we will update this policy to describe the information involved.
6. Data location and security
Connections to the site use HTTPS (TLS). Server-side processing (for the tools listed in section 1) takes place on infrastructure located in the European Union. Passwords you enter for the Protect and Unlock tools are used only in your browser and are not transmitted to us.
7. Your rights and choices
Depending on where you live, you may have rights over personal data that advertising or analytics partners process — such as access, deletion, or opting out of the “sale” or “sharing” of data for targeted advertising. You can exercise ad choices using the tools linked in section 3, and you can contact us for other requests.
8. Children
The service is not directed to children under 13, and we do not knowingly collect their personal information.
9. Changes
We may update this policy from time to time; the date above reflects the current version.
