ToolCenterLab is designed with privacy as a core principle. All 96 tools — from PDF compressors and mergers to text formatters, image editors, and developer utilities — process your data entirely within your web browser using client-side JavaScript and WebAssembly.
No files, text, images, or calculations are ever sent to our servers. When you compress a PDF, generate a password, or remove an image background, your data never leaves your device.
Because all processing happens client-side, we do not collect, store, or have access to:
We use your browser's localStorage to save your preferences, such as favorite tools and recently used tools. This data is stored only on your device and is never transmitted to any server. You can clear it at any time through your browser settings.
We use Google Analytics 4 to understand how visitors interact with the site — which pages are visited, how long sessions last, and which tools are most popular. Google Analytics collects anonymized usage data and may set cookies. No personally identifiable information is collected through analytics. You can opt out by using a browser extension like Google Analytics Opt-out.
The only cookies used on this site come from Google Analytics for anonymized site usage analytics.
ToolCenterLab itself does not set any cookies. We use localStorage (not cookies) for user preferences such as favorite tools and theme selection.
Since we do not collect personal data, there is generally nothing to request deletion of. However, you can clear all locally stored preferences (favorites, recent tools) by clearing your browser's site data for toolcenterlab.com. If you have any privacy-related concerns, contact us and we will respond promptly.
We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date.
If you have questions about this privacy policy, please contact us at [email protected].
