Privacy Policy

Last updated: October 18, 2026Your privacy is our top priority.

Data Controller

The data controller responsible for the processing of personal data described in this Privacy Policy is PDF Compressor, reachable by mail at PMB 2000 NE 42nd Ave, Ste D Unit 2241, Portland, OR 97213, United States, and by email at [email protected]. If you have any question about how your data is handled, this is the entity to contact.

Local Processing

All PDF compression is performed locally in your browser. Your files are never uploaded to our servers.

Your Files Are Never Collected

We do not collect, store or transmit your PDF files or their contents. Analytics and advertising data are described below.

Cookies

We use Google Analytics and Google AdSense cookies; where the law requires it (for example in the EU and UK), only after you consent. We set no language cookie: your language is carried in the page address. The site also uses your browser's local storage (not cookies) to remember your theme, whether you dismissed the language suggestion, and your recent compression history (file names, sizes and times only). You can change your cookie choices at any time under Privacy settings in the footer.

Your compression history (file names, sizes and times) is saved only in your browser's local storage on this device. It is never uploaded, and you can clear it at any time from the history section on the home page or by clearing your browser data.

Third-Party Services

This website may use Google AdSense to display advertisements. Google may use cookies to serve ads based on your prior visits to this website or other websites.

We may also use Google Analytics to analyze website traffic and usage patterns. This helps us improve our service but does not involve processing your PDF files.

You can review or opt out of personalized advertising at any time through Google's Ad Settings at https://adssettings.google.com.

Categories of Data We Process

We keep the amount of personal data we process to a strict minimum. Below is a complete breakdown of what we do (and do not) process.

Your PDF Files

Your PDF files are never uploaded to our servers. Every operation (compression, merging, splitting, rotation, watermarking, page extraction, and PDF-to-image conversion) runs entirely inside your browser using JavaScript Web Workers together with libraries such as pdf-lib and pdf.js. The file never leaves your device, and once you close the browser tab, the file and any in-memory processing data are gone. We have no server-side storage, database, or backup that could contain your document, and no employee or automated system at PDF Compressor ever has access to its contents.

Technical and Usage Data

Like most websites, our servers and third-party providers automatically log limited technical information, such as browser type, device type, approximate location derived from IP address, referring page, and pages visited, through Google Analytics. We set no language cookie, because your language is carried in the page address. We do store your theme (light/dark) preference, whether you dismissed the language suggestion, and your recent compression history (file names, sizes and times) in your browser's local storage on your device, so the site remembers them on return visits. None of this technical data is linked to the contents of your PDF files, because those files are never transmitted to us in the first place.

Legal Basis for Processing (GDPR Article 6)

Consent: Article 6(1)(a) GDPR

Where we or our partners such as Google use cookies for personalized advertising or analytics that require your consent under applicable law (including the EU GDPR and ePrivacy rules), the legal basis for that processing is your consent, which you may withdraw at any time with future effect.

Legitimate Interest: Article 6(1)(f) GDPR

We rely on our legitimate interest in operating, securing, and improving a free website (for example, basic server logs needed to keep the service running and prevent abuse) where such processing is proportionate and does not override your fundamental rights and freedoms.

Your Rights Under GDPR

If you are located in the European Economic Area, the United Kingdom, or another jurisdiction with similar data protection laws, you have the following rights regarding any personal data we hold about you:

  • Right of access: you can ask us to confirm whether we process personal data about you and to obtain a copy of it.
  • Right to rectification: you can ask us to correct inaccurate or incomplete personal data.
  • Right to erasure: you can ask us to delete your personal data where there is no legitimate reason for us to continue processing it.
  • Right to data portability: you can ask to receive your personal data in a structured, commonly used, machine-readable format.
  • Right to object: you can object to processing based on legitimate interest, including for direct marketing or profiling purposes.
  • Right to withdraw consent: where processing is based on consent, you can withdraw it at any time without affecting the lawfulness of processing carried out before the withdrawal.

To exercise any of these rights, contact us at [email protected] or by mail at the address listed above. We will respond within the timeframe required by applicable law.

Data Retention

We do not retain your PDF files at all, because they are never transmitted to our servers, so there is nothing to delete. Analytics data collected through Google Analytics is retained according to Google's own retention settings for this property; language and theme preferences stored in your browser persist until you clear your browser storage or cookies.

International Data Transfers

PDF Compressor is based in the United States. Where analytics or advertising partners such as Google process technical data outside of your country of residence, including in the United States, such transfers rely on the safeguards those providers make available (such as Standard Contractual Clauses) to ensure an adequate level of protection for your personal data.

Right to Lodge a Complaint

If you believe our processing of your personal data infringes applicable data protection law, you have the right to lodge a complaint with a supervisory authority, in particular in the EU member state of your habitual residence, place of work, or the place of the alleged infringement.
