LOCAL PROCESSING, EXPLAINED
Your files stay yours.
Your files are processed in your browser, not uploaded to PDF Tool Chest or shared with advertisers.
Local files. Local processing.
Choose a file, use a tool, and save the result to your device. Your document contents stay with you.
When you choose a file
Your browser reads the file, creates previews, and performs the work on your device. Downloads go to the location you choose or your usual downloads folder.
This site has no document-upload endpoint or cloud file-storage account.
What uses the internet?
The website loads its pages and assets. PDF and Word tools also download version-pinned processing libraries from public CDNs. These requests fetch code, not your document contents.
Hosting and configured ad providers may receive normal connection details, such as your IP address and the page requested. Local processing does not mean the site has no network traffic.
Advertising stays separate
Ads appear in sandboxed frames, separate from the file workspace. This package includes placeholders, not a live ad network. No filenames, document data, previews, or passwords are sent to those frames.
Any future ad integration must keep that separation. Cookie and tracking disclosures depend on the provider and configuration.
What is remembered?
Only your chosen theme and import settings are saved in this browser. Document contents are not saved in local storage or carried between tools.
Download before clearing files, switching tools, refreshing, or closing. These actions release the app's file references and previews; they are not secure erasure. The browser manages memory cleanup. Your originals and downloaded results remain on your device.
Keep the original
File formats and available memory affect what a tool can process. A 600 DPI flattened PDF can be larger than its source. Image flattening converts color to RGB, and Word conversion can change layout.
Keep the original and review important or color-critical work before printing.
