SnapLocal — Private Screenshot & Annotation

Capture, annotate and mosaic screenshots 100% locally. Your shots are never uploaded. Annotation tools are free, forever.

YOUR SCREENSHOTS NEVER LEAVE YOUR MACHINE. SnapLocal is a privacy-first screenshot and annotation tool for Chrome. Every capture is processed, stored, and exported entirely on your device — no servers, no cloud, no uploads. Ever. Unlike Lightshot (which uploads every shot to a public server), Nimbus (which locks mosaic behind a $60/year paywall), or GoFullPage (which charges for exports), SnapLocal gives you the full annotation toolkit for free and keeps your pixels where they belong: on your machine. ─── WHY SNAPLOCAL ─── 🔒 ZERO UPLOADS — ARCHITECTURE, NOT A PROMISE SnapLocal has no server to upload to. No host_permissions. No network requests. Your screenshots physically cannot leave your device. Airplane mode works. 🖼️ ALL ANNOTATION TOOLS FREE — INCLUDING MOSAIC Arrow, rectangle, ellipse, text, brush, and pixel-perfect mosaic/blur redaction. Every tool ships in the free tier. No "upgrade to blur sensitive info" nonsense. 💳 ONE-TIME PRO. NO SUBSCRIPTION. Pro is $19 once. That's it. No monthly nag, no free-trial-to-credit-card trap, no dark patterns. Pay once, own it forever. ⚡ INSTANT & OFFLINE Hotkey to capture in under 50ms. No spinner, no "uploading…", no sign-in wall. It's a tool, not a service. 🔐 NO ACCOUNT REQUIRED No sign-up, no email, no OAuth.
