Honest, verifiable writing about private screenshot tools, screenshot redaction, and where your captures actually end up. No affiliate noise, no data-harvesting pixels — this page loads zero external requests, just like the extension.
A step-by-step local workflow: capture tightly, annotate locally, destroy sensitive pixels with a real mosaic, export deliberately. Ends with a three-check privacy audit you can run against any screenshot tool in five minutes.
Snipping Tool quietly syncs captures to OneDrive. Greenshot is local but frozen, with a blur instead of a true mosaic. SnapLocal is browser-native, zero-upload, and ships a pixel-destructive redactor free. All three compared.
ShareX is endlessly configurable and ships with upload workflows enabled by default. SnapLocal has no upload code path at all — Chrome wouldn't let it. An honest side-by-side, including where ShareX is still the better choice.
Today we bring SnapLocal to Product Hunt. A Chrome extension with
no host_permissions, zero network requests,
chrome.storage.local for everything, and offline ECDSA
license verification. Free annotations, one-time $19 Pro, no subscription.
Lightshot uploads captures to public, guessable URLs on its servers.
SnapLocal has no upload code path at all — no host_permissions,
zero network requests, everything stored in chrome.storage.local.
A side-by-side look at the two architectures and what each one means for your data.
A step-by-step local workflow for screenshot redaction: capture only what you need, destroy pixels with a free mosaic tool, crop away the edges, verify, and export — without the image ever touching a third-party server.
SnapLocal, Lightshot, Nimbus, GoFullPage and the built-in OS tools, compared on the two things that actually matter for privacy: does the capture get uploaded, and what does the tool cost. With a full comparison table.
