Useful document work without unnecessary uploads
BQ PDF Tools provides focused PDF utilities for common tasks such as merging, splitting, rotating, converting, numbering, watermarking, and inspecting documents.
The site is part of the independent BQ Tools ecosystem. Its visible logo follows the BQ subdomain format: BQPDFTools, while the browser title uses the spaced form BQ PDF Tools.
Local processing
Core document processing is performed by code loaded into the browser. The application does not require an account, external PDF API, or application database to transform a selected file.
Installable offline app
Supported browsers can install the site and cache its static pages, interface code, PDF libraries, and worker files. The offline cache contains application resources only. Documents selected from the device are kept in temporary browser memory and are not stored by the service worker.
Private personalization
Favorites and recently opened tools store only tool identifiers in this browser so useful actions are easier to find again. No selected document, filename, or generated result is saved by this feature.
Batch processing and recovery
The batch queue processes one PDF at a time and can continue after an individual failure. Privacy-safe diagnostics describe the tool, browser, file count, total size, and visible error without including filenames or document contents.
Accessibility and session resilience
The interface includes large-text and high-contrast options, reduced-motion controls, keyboard shortcuts, focus-aware status messages, and settings-only recovery within the current browser tab. Session recovery stores non-text form options only; it never stores selected files or filenames.
Practical limitations
Browser-based processing depends on device memory and browser capabilities. Huge, encrypted, damaged, digitally signed, or highly unusual PDFs may fail. A generated file should always be reviewed before the original is deleted.
