Completely free
Every SnapDiff feature is free, with no paid plan, subscription, or activation key.
SnapDiff is completely free for personal and professional use. There is no checkout, subscription, paid tier, or activation key.
What is included
- Unlimited capture, A/B and Multi comparison, annotations, and a local library.
- Full-quality PNG, JPEG, WebP, and local image-based A4 PDF exports.
- Optional local axe accessibility checks and saved JSON reports.
- Clean exports or a custom name watermark, with optional timestamps.
- Responsive viewport presets, custom viewports, and browser locale simulation in Chrome.
Firefox supports core capture, comparison, annotations, exports, accessibility checks, and watermark controls. It does not support new responsive or localized captures. See browser feature availability.
How a workflow is counted
A completed Single capture, A/B pair, or Multi group counts as one workflow in your local history. Retakes, annotations, exports, and accessibility checks do not add workflows. These counts do not restrict use.
Capture and export safety limits still apply. Export guidance explains large-image and PDF limits.
Updating an existing installation
All features become available when your browser installs this version. Existing captures, annotations, accessibility reports, and watermark preferences remain local. No activation or internet connection to a payment service is required. If an older copy still shows upgrade controls, update it through its official browser store and reopen SnapDiff.
Next: run an accessibility check or choose watermark and timestamp settings.
