SnapCanvas - screenshot app

SnapCanvas - screenshot app is a commercial desktop application for Linux that combines screenshot capture, editing, privacy controls, and sharing in one workflow. It is designed for professionals, support teams, developers, accountants, and creators who prepare visual material from their computers. The app can support documentation, bug reports, and social media work, as well as general screenshot tasks. Its privacy-focused workflow keeps OCR and sensitive-data redaction on the computer by default.

Capture options include precise regions, selected windows, full screens, and stitched images from multiple monitors. A configurable delay from 0 to 10 seconds, global shortcuts, and system tray actions help capture menus, tooltips, and hover states. Users can add arrows, lines, geometric shapes, freehand marks, highlighters, numbered callouts, and text boxes, with non-destructive layers, cropping handles, and undo and redo. Framing controls include padding, corner radius, drop shadows, aspect ratios, custom backgrounds, gradients, text or logo watermarks, and reusable presets. Offline OCR supports English, Polish, German, French, Spanish, and Italian, while QR code detection can open links or copy decoded text.

SnapCanvas can detect emails, IBAN bank accounts, VAT or NIP tax identifiers, national IDs, credit card numbers, and phone numbers for automatic masking. Redaction styles include blur, noise, and blackout, and Local-Only Mode can cut off external network calls completely. An ephemeral clipboard option clears copied screenshots after 60 seconds, and the application also provides flexible file uploading. In MirrorNest, SnapCanvas is presented in the video category as a Linux screenshot and visual-content tool. MirrorNest links directly to the official release instead of mirroring the software, so the commercial license and release access are handled through the official source.
