Secure PDF Handling

We strictly enforce local memory processing. There is no server retention, meaning temporary handling ensures automatic cleanup the moment you close the tab.

Works Offline

SafeTools features comprehensive PWA support. Experience true offline PDF merging with zero internet dependency and reduced data exposure.

Supported Formats

We don't just merge PDF files. SafeTools supports embedding various image formats directly into your document. Currently supported formats include PDF, PNG, JPG, JPEG, and WEBP. Images are automatically fitted to the page layout for a seamless reading experience.

Zero File Size Limits

Because everything happens in your local browser environment, there are no artificial file size limits. Merge 10MB or 1GB files without encountering paywalls or upload restrictions—your only limitation is your device's RAM capacity.
