KeptPDF VS ExifVoid

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.

ExifVoid's answer:

Most metadata removal tools upload your files to remote servers — you're handing your private data to a third party in order to remove it. ExifVoid processes everything locally in your browser using JavaScript. No uploads, no server storage, no accounts. It also goes beyond simple removal by showing you a full privacy scan with threat categories, risk scoring, and a GPS map of your photo's location. No other free tool offers that level of visibility before cleaning.

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.

ExifVoid's answer:

ExifVoid is the only photo metadata tool that combines a visual privacy risk scanner with 100% client-side processing. It doesn't just remove EXIF data — it shows you exactly what's hidden in your photos, scores the privacy risk, and displays GPS coordinates on an interactive map, all before you clean. Your files never leave your browser. Most competitors upload your photos to their servers for processing, which defeats the purpose of a privacy tool

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.

ExifVoid's answer:

Anyone who shares photos online and cares about privacy. This includes eBay and marketplace sellers whose product photos may expose their home address, online daters who want to protect their location, journalists and activists who need to strip metadata to protect sources, photographers managing what data they share publicly, and businesses handling customer photos under GDPR. If you share photos with strangers, ExifVoid is for you.

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.

ExifVoid's answer:

I discovered that every photo I'd ever listed on eBay contained my exact home GPS coordinates — accurate to a few metres. When I looked for a tool to fix this, every option either uploaded my files to a server or was a complex command-line tool. I wanted something simple: drop in a photo, see what's hidden, remove it, done. And it had to work entirely in the browser so my files never left my device. That's ExifVoid.

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.

ExifVoid's answer:

Next.js 14 with static export for the framework, Tailwind CSS for styling, the exifr library for reading EXIF/XMP/IPTC metadata, Leaflet with OpenStreetMap for displaying GPS coordinates on a map, and canvas re-encoding for metadata stripping. Hosted on Vercel with automatic deployments from GitHub. The entire tool runs client-side — there is no backend server.

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.

ExifVoid's answer:

ExifVoid is a free tool for individual users, not an enterprise product. You can skip this one or write:
