Questions & Answers

As answered by people managing DumPDF and Sejda.

What makes your product unique?

DumPDF's answer

DumPDF ("Don't Upload My PDF") runs 100% client-side inside the user's web browser with zero remote server file uploads:

  • Zero-Server Processing: Merges, splits, compresses, and edits documents locally on your device hardware without transmitting files over the internet.
  • True Offline Capability: Operates fully without an active internet connection once loaded or installed as a Progressive Web App (PWA).
  • Zero Data Footprint: Requires no accounts, stores no session logs, and utilizes no trackers or file retention caches.

Why should a person choose your product over its competitors?

DumPDF's answer

Traditional online PDF tools upload confidential files to external servers, creating third-party exposure risks and queue bottlenecks:

  • Absolute Document Privacy: Eliminates data leak risks for confidential records, tax documents, and legal filings.
  • Hardware-Accelerated Speed: Processing files directly in-browser removes upload and download latency, allowing near-instant operations.
  • No Paywalls or File Limits: Provides unlimited document processing without daily quota caps, artificial size restrictions, or forced subscriptions.

How would you describe the primary audience of your product?

DumPDF's answer

DumPDF is designed for users handling sensitive files under strict privacy standards:

  • Legal & Judicial Professionals: Attorneys, paralegals, and judges handling sealed court filings, contracts, and case files.
  • Finance & Accounting Specialists: CPAs, auditors, and tax professionals managing client W-2s, returns, and financial audits under compliance rules.
  • Privacy-Conscious Users & Developers: Anyone seeking a zero-trust alternative to cloud-reliant utilities like Smallpdf or iLovePDF.

What's the story behind your product?

DumPDF's answer

DumPDF was created by developers and privacy advocates frustrated by the lack of secure tools for basic document tasks:

  • Frustration with Cloud Lock-in: Mainstream web-based PDF converters consistently demand that users upload personal documents to remote cloud storage.
  • A Stand for Local Execution: The founders recognized that modern browser capabilities eliminate the need for server-side processing entirely.
  • Mission-Driven Privacy: Built as a free, lightweight, privacy-first utility to give users total control over their data without third-party exposure.

Which are the primary technologies used for building your product?

DumPDF's answer

DumPDF leverages high-performance, in-browser execution technologies:

  • WebAssembly (Wasm): Delivers near-native binary execution speeds for resource-heavy operations like local OCR and file compression.
  • Client-Side JavaScript Engines: Orchestrates PDF page reordering, watermarking, password encryption, and metadata scrubbing directly in memory.
  • Progressive Web App (PWA) Standards: Enables cross-platform installation and offline functionality across desktop and mobile browsers.

Who are some of the biggest customers of your product?

DumPDF's answer

  • Legal firms and independent attorneys redacting and merging confidential case files
  • Accounting practices and tax advisors encrypting and organizing client financial returns
  • Healthcare and compliance teams processing patient forms without violating HIPAA or GDPR data-transfer rules
  • Remote workers and students needing fast, offline-capable PDF conversion on the go
