OpenCapture.app

Capture an entire scrolling web page as one image or PDF, then crop, annotate and blur โ€” all processed locally in your browser. Free and open source, for Chrome, Firefox and Edge. No account, no upload.

Tired of screenshot tools that quietly upload your pages to a server? OpenCapture captures an entire scrolling web page as one seamless image, then lets you crop, annotate, blur or redact anything sensitive, and export to PNG or PDF โ€” every pixel operation runs locally in a Rust/WebAssembly core inside your own browser.

No account, no cloud, no telemetry. Unlike Awesome Screenshot and Lightshot, which route captures through their own infrastructure, and unlike ShareX, which is Windows-only, OpenCapture runs on Chrome, Firefox and Edge with all processing on-device โ€” and it's open source under AGPL-3.0, so the privacy claim is auditable rather than a promise.

Three capture modes are available โ€” full page, visible area, and selected region โ€” and the last 50 captures stay in a local history that never syncs anywhere.

Everything is free. The only paid feature is watermarking, unlocked with a one-time credit purchase rather than a subscription.

Questions & Answers

As answered by people managing OpenCapture.app.

  1. Which are the primary technologies used for building OpenCapture.app?

    A Rust core compiled to WebAssembly handles the image work โ€” stitching, cropping, scaling, blurring and PDF generation โ€” which is what makes it fast enough to run entirely client-side. Around it is a browser extension built on the WebExtensions API, so one codebase ships to Chrome, Firefox and Edge. Licensed under AGPL-3.0.

  2. What makes OpenCapture.app unique?

    Most full-page screenshot extensions send your capture to a server to stitch or store it. OpenCapture does all of it on your machine โ€” stitching, cropping, annotation, blurring and PDF export all run in a Rust/WebAssembly core inside your browser. No account, no upload, no telemetry.

    Because it's open source under AGPL-3.0, that claim is auditable rather than something you have to take on faith.

  3. Why should a person choose OpenCapture.app over its competitors?

    If you're capturing internal dashboards, customer records, or anything under NDA, where the screenshot goes matters as much as how it looks.

    Awesome Screenshot and Lightshot route captures through their own infrastructure. ShareX keeps everything local but is Windows-only and isn't a browser extension. GoFullPage is closed source, so you can't verify what it does with a page.

    OpenCapture is the combination that's otherwise hard to find: a browser extension for Chrome, Firefox and Edge, fully local, and open source. It's also free โ€” the only paid feature is watermarking, a one-time $5 unlock rather than a subscription.

  4. How would you describe the primary audience of OpenCapture.app?

    Anyone who captures pages that shouldn't leave their machine: engineers and QA saving internal tools and bug repros, designers archiving reference pages, support teams documenting customer accounts, researchers and journalists preserving sources, and people in regulated environments where a cloud upload simply isn't allowed.

    It's also a straightforward free option for anyone who just wants a whole page saved as a PNG or PDF without signing up for anything.
