QuickTools.one VS KeptPDF

QuickTools.one's answer

QuickTools.one is a collection of browser-based tools that run entirely on your device. Nothing is uploaded, stored, or tracked. Every task, merging PDFs, resizing images, converting files, happens locally in your browser. This privacy-first approach sets it apart from other “free” tools that rely on servers or data collection.

KeptPDF's answer:

KeptPDF runs entirely in your browser. Your file, and the text inside it, never leaves your device. Not to an AI, not even to us. You can open your browser's network tab and watch: the document bytes never go out.

Most online PDF tools upload your file to a server first, and some "AI redaction" services quietly send your document text to a third-party model. That is the exact risk people are trying to avoid when they redact something.

KeptPDF also does true redaction. The text is removed from the file, not covered with a black box you can copy out later. Every redaction produces a verification certificate you can share with the file.

QuickTools.one's answer

Because it’s fast, private, and honest. Most online utilities upload your files to the cloud, add watermarks, or limit free use. QuickTools.one skips all that. It’s completely free, watermark-free, and processes everything locally. You get instant results, no waiting, no tracking, and full control of your files.

KeptPDF's answer:

Three reasons.

Privacy you can verify, not just a promise. Processing happens locally in the browser, so there is no upload step to trust. We do send anonymous usage counts for quota, and we say so plainly, but never your document.

Real redaction with proof. Removed text is permanently gone, and you get a certificate showing the file was checked for leftover extractable text. Automated detection cannot catch everything, so a final human review is still your job, and the tool says that too.

It works on a phone. Most PDF suites assume a desktop. KeptPDF was built and used on a phone first, so redacting a document while you are standing in a hallway actually works.

QuickTools.one's answer

QuickTools.one is built for everyday users who value speed and privacy, students, freelancers, and small-business owners who regularly need to handle simple file tasks without signing up for another account or trusting cloud uploads.

KeptPDF's answer:

Anyone who has to hand a document to someone else and needs the sensitive parts gone first.

In practice that is solo attorneys and small law firms, accountants and tax preparers, healthcare and records staff handling requests, HR teams, and individuals dealing with their own medical, legal, or financial paperwork.

The common thread is not an industry. It is a person who cannot upload a confidential file to a random website, and who does not have an enterprise IT budget to solve it.

QuickTools.one's answer

QuickTools.one started from frustration with “free” PDF and image tools that weren’t truly free or private. The goal was to build a clean, modern alternative: fast utilities that just work inside your browser. It began with a PDF merger and expanded into a growing set of privacy-first everyday tools.

KeptPDF's answer:

A family member got seriously ill. We spent most days at the hospital, and straight answers were hard to come by, so we leaned on AI tools to make sense of the records, notes, and lab results.

But you cannot paste a medical record into an AI chat. You have to strip the names, the ID numbers, the diagnoses first. And almost every tool we found either wanted to upload the whole file to a server, or "auto-redacted" by sending the document text to an online AI. That was the exact thing we were trying to avoid.

Most of this was happening on a phone, at a bedside. So I built the tool I needed: redaction that runs on the device, works on mobile, and never sends the file anywhere. That turned into KeptPDF, which is now a full PDF suite with over 20 tools, all local-first.

QuickTools.one's answer

QuickTools.one is built with Next.js and TypeScript, using WebAssembly for local file processing and the Canvas API for image manipulation. It’s deployed on Vercel for high performance and global CDN caching. All tools run entirely in the browser with no backend file storage.

KeptPDF's answer:

The app is plain JavaScript with no front-end framework, which keeps it fast and keeps the code auditable.

PDF work happens in the browser using pdf.js for rendering and pdf-lib for writing. Text recognition uses Tesseract running as WebAssembly. Password and encryption handling uses a WebAssembly build of qpdf. It is a Progressive Web App, so it installs and works offline.

The thin server side is Node on Vercel, with Postgres for accounts, Stripe for billing, and Resend for email. None of those ever see a document.

QuickTools.one's answer

QuickTools.one is a free public platform used by: • Freelancers and students managing daily document tasks • Small businesses that need quick PDF and image tools • Privacy-conscious users who prefer local, offline-style utilities

(QuickTools.one does not track or identify users, so exact organizations are not recorded.)

KeptPDF's answer:

KeptPDF is early and independent, and we do not publish customer names. The product is privacy-first by design: we never see your documents, and we do not track who our users are or what they work on. Publishing a client list would sit badly next to that.

The user base today is mostly solo attorneys, small firms, accountants, and individuals handling their own records.
