You're on a borrowed laptop, a work machine where you can't install software, a public computer at a library, or just don't want another app eating disk space. The PDF needs editing now. Installing isn't an option.
Browsers are everywhere. Browsers can edit PDFs.
Browser-based is the universal answer
Flint runs in any modern browser — Chrome, Edge, Safari, Firefox, Brave, Arc. No install, no admin permissions needed, no add-ons. Open URL, drag PDF in, edit, download.
Works on Mac, Windows, Linux, Chromebook, iPad, iPhone, Android — anywhere a browser runs.
What's possible without install
Edit text, sign, merge, split, rotate, delete pages, compress, convert to Word, annotate, redact, password-protect, unlock. Full PDF toolkit in a browser tab.
Privacy of no-install tools
Flint processes files in your browser session and doesn't store them permanently. Files don't stay on Flint's servers after the session ends. For sensitive PDFs, that's better than downloading an unknown app from a marketplace.
FAQ
Will this work on a work computer with restrictions?
Almost always. Work computers usually allow web browsing even when they block installs. Flint loads in any allowed browser. No admin permissions required.
Is browser-based slower than installed software?
For everyday PDF tasks (edit text, sign, merge a few files), no — performance is comparable. For very large or complex jobs (hundreds of files, advanced redaction), native apps may win. Most users never hit that ceiling.
What about offline use?
Browser tools need an internet connection. For offline work, you'd need an installed app. For typical connected use, browser is faster and lighter.
No install needed. Open Flint in any browser and edit.
