KeptPDF is a PDF toolkit that runs entirely in your browser. Nothing uploads: every tool runs on your own device, so the document never touches a server.

Features and specs

What each product offers, as listed by its team.

PuTTY 5 features
KeptPDF 5 features
  • Free and Open Source
    PuTTY is free to use and its source code is openly available. This allows flexibility for users to modify it according to their needs and ensures that there are no licensing costs associated with its usage.
  • Wide Protocol Support
    PuTTY supports various network protocols including SSH, Telnet, SCP, and SFTP. This makes it versatile for different types of server management and data transfer tasks.
  • Lightweight
    PuTTY is a lightweight application that consumes minimal system resources, making it suitable for use on older or less powerful systems without significant performance degradation.
  • Extensible Configuration Options
    PuTTY offers a wide range of configuration options for terminal emulation, keyboard mappings, and connection settings, giving users fine control over their connections and workflow.
  • Portability
    PuTTY can be run as a portable application from USB drives or other external storage devices without the need for a formal installation process on the host system.

Possible disadvantages

  • No Integrated File Manager
    Unlike some other SSH clients, PuTTY does not come with an integrated file manager, which can make tasks involving file transfers less convenient without the use of PuTTY's separate utilities like PSCP or WinSCP.
  • Limited Scripting Capabilities
    PuTTY itself lacks advanced scripting capabilities which can be a limitation for users who need to automate sessions or workflows extensively. External tools or extensions are necessary for these needs.
  • Basic User Interface
    The user interface of PuTTY is quite basic compared to modern applications. It lacks some of the polished features and aesthetics that other terminal clients might offer.
  • No Tabbed Sessions
    PuTTY does not natively support multiple tabbed sessions within a single window, which can make managing multiple connections less convenient. Users typically need to open multiple instances of the application.
  • Windows-Centric
    While PuTTY is primarily developed for Windows, its cross-platform capabilities through ports like PuTTY for Mac or Linux are not as well-supported, leading to potential inconsistencies and lack of features compared to the Windows version.
  • Simple PDF Editing
    KeptPDF offers straightforward tools for editing, merging, splitting, and converting PDF files, making it accessible for users who need quick document management without a steep learning curve.
  • Web-Based Accessibility
    Being a web-based tool, KeptPDF can be accessed from any device with an internet connection, eliminating the need for software installation and allowing use across different operating systems.
  • Multiple File Format Support
    The platform supports conversion between PDF and various other file formats, offering flexibility for users who work with documents in different formats.
  • No Installation Required
    Since it operates in a browser, users can save storage space on their devices and avoid compatibility issues that sometimes arise with desktop software installations.
  • Quick Processing
    KeptPDF is designed to process PDF tasks efficiently, allowing users to complete common document tasks like compression or conversion in a relatively short amount of time.

Questions & Answers

As answered by people managing PuTTY and KeptPDF.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

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.
