Privacy Policy

Last updated: October 18, 2026

Your documents

PDFs you add to our compressor are read, compressed and written entirely in your browser using Web Workers and WebAssembly. They are never uploaded to our servers or shared with anyone. They only exist in your browser tab’s memory until you download them or close the page.

Settings stored on your device

The compressor may remember your chosen settings in your browser’s local storage so they are ready next time. This data never leaves your device, and you can clear it by clearing site data in your browser.

Website data

Like most websites, our hosting provider may log basic technical information (such as IP address, browser type and pages visited) for security and to keep the site running. If we add analytics or advertising in the future, they may use cookies, and we will update this policy first.

Contact form

If you contact us, we receive the name, email address and message you send, and use them only to reply to you.

Children

The site is not directed at children under 13, and we do not knowingly collect their personal information.
