Features and specs

What each product offers, as listed by its team.

PDFStart 4 features
GhostDocs 5 features
  • Convenient PDF access
    Tools branded as PDFStart generally aim to put common PDF tasks such as converting, editing, merging or viewing in one place, which can save time compared with searching for separate tools. I could not verify the exact feature set on pdfstart.com, so check the site for specifics.
  • Likely simple, task-focused interface
    Online PDF utilities of this kind usually have a minimal interface where you upload a file and pick an action, so non-technical users can get started quickly. Confirm this by trying the tool on a non-sensitive document.
  • No heavy software install (if web-based)
    If the service runs in the browser, it works across operating systems without installing desktop software. This is useful for occasional use or on shared and locked-down computers.
  • Possible free tier for basic tasks
    Many comparable services let users try basic functions for free before asking them to pay. This lets you test output quality before committing, but check the site for the actual pricing and limits.
  • Zero Cloud Uploads
    All processing runs 100% locally in your browser via WebAssembly & HTML5 Canvas.
  • Permanent Redaction
    Flattens document canvas to destroy underlying text layers, preventing copy/paste leaks.
  • Offline Functionality
    Fully operational in Airplane Mode with zero active internet connection.
  • Binary EXIF Stripper
    Scans and strips GPS coordinates and device fingerprints without recompressing images.
  • No Registration Required
    Instant access with no accounts, logins, or artificial file quotas.

Questions & Answers

As answered by people managing PDFStart and GhostDocs.

What makes your product unique?

GhostDocs's answer:

GhostDocs operates on a 100% zero-upload architecture. While conventional document tools upload files to remote servers, GhostDocs executes all PDF splitting, merging, redaction, and image conversions locally inside your browser using HTML5 Canvas and WebAssembly. You can disconnect your internet, turn on Airplane Mode, and every tool still works.

Why should a person choose your product over its competitors?

GhostDocs's answer:

Complete privacy, no paywalls, and no file limits. Competitors like iLovePDF and Smallpdf upload your files to their servers and restrict usage behind daily limits or paid subscriptions. GhostDocs processes documents directly in your device's RAM with no file size limits, no watermarks, and zero account sign-up required.

How would you describe the primary audience of your product?

GhostDocs's answer:

Privacy-conscious professionals, remote workers, legal and financial consultants, journalists, and everyday web users who need to handle sensitive documents (such as tax filings, bank statements, contracts, and ID scans) without risking cloud leaks.

Who are some of the biggest customers of your product?

GhostDocs's answer:

  • Independent legal and accounting professionals
  • Freelancers and remote teams
  • Privacy-conscious everyday web users

What's the story behind your product?

GhostDocs's answer:

We created GhostDocs after realizing that simple everyday tasks—like blacking out an account number or combining two pages—forced users to upload confidential documents to anonymous cloud servers. We engineered a suite of zero-upload browser tools to prove that modern web apps can deliver fast, professional utility without sacrificing user privacy.

Which are the primary technologies used for building your product?

GhostDocs's answer:

React, TypeScript, Vite, WebAssembly, HTML5 Canvas API, pdf-lib, pdfjs-dist, and binary EXIF parsers.
