OpenScreenSHot
Free, open-source Chrome extension for full-page screenshots
I built OpenScreenShot because every screenshot extension I tried eventually asked me to sign up, watch an ad, or trust that my captures weren't being uploaded somewhere. For a tool that literally sees everything on your screen, that never sat right with me.
The important part: zero data leaves your device. No account, no telemetry, no third-party servers. It's fully open source (MIT) — you can read every line, and contributions are welcome.
It's free, and it stays free.
Would genuinely love your feedback — what's the one feature that would make this your default screenshot tool?
Features
📄 Full-page capture — scrolls and stitches long pages top to bottom, including apps that scroll an inner panel (Gmail, Notion, chat apps)
👁 Visible area and ✂️ region capture
✏️ Annotate — arrows, text, shapes, crop — right after you capture
📤 Export as PNG, JPEG, WebP, or PDF, or copy straight to clipboard (Cmd/Ctrl+C)
Use Cases
🐛 Bug reporting & QA
Capture exactly what went wrong and annotate it before sharing.
- Full-page screenshots of long pages
- Highlight issues with arrows and boxes
- Blur sensitive user information
- Export to PDF for bug reports
Example:
Capture an entire checkout flow, circle the broken button, blur customer information, attach to a Jira ticket.
🎨 Design reviews
Perfect for designers and product teams reviewing UI changes.
- Compare before/after designs
- Mark spacing or alignment issues
- Annotate typography and colors
- Share feedback without needing Figma access
📚 Documentation
Create clean documentation for internal wikis or user guides.
- Capture long settings pages
- Crop unnecessary sections
- Add callouts and numbered annotations
- Export as PNG or PDF
Example:
Internal onboarding guides with screenshots of every step.
💼 Client communication
Instead of describing problems in email:
- Screenshot
- Draw arrows
- Blur confidential data
- Send a polished image
This reduces back-and-forth significantly.
🔍 Research & competitive analysis
Save websites as visual references.
Examples:
- Competitor landing pages
- Pricing pages
- Marketing campaigns
- Product feature comparisons
Since it captures the entire page, you don't need multiple screenshots. Full-page capture is particularly useful for preserving a page's state for later comparison.
📝 Education & tutorials
Teachers and content creators can:
- Capture learning resources
- Annotate important sections
- Blur personal information
- Export for presentations or course materials
🔒 Privacy-sensitive work
One of its biggest differentiators.
Because processing happens locally:
- Internal dashboards
- Customer records
- Financial reports
- Admin panels
- Healthcare portals
never leave your machine during capture or editing.
📄 Compliance & record keeping
Useful when you need evidence of what a webpage looked like.
Examples:
- Terms of service
- Pricing changes
- Regulatory notices
- Support conversations
PDF export makes archiving straightforward.
📢 Marketing & social content
Capture webpages and polish them before sharing.
- Crop to the important section
- Add annotations
- Export high-quality PNG/WebP
- Use in presentations or social posts

OpenScreenSHot has great potential and offers some useful features, but I encountered a few issues that could be improved. Please contact me so I can share detailed feedback and suggest the changes I'd like to see. Email: [email protected]
The local-only processing is the strongest differentiator here, especially for QA teams capturing dashboards with customer data. How does full-page capture handle virtualized lists or pages that lazy-load content while scrolling? An option to show which elements were skipped would make privacy-sensitive bug reports even more trustworthy.
Love the privacy-first approach and the fact that everything stays on the device. The built-in annotation tools also make this feel much more complete than a basic screenshot extension. A batch mode for capturing multiple URLs with the same settings and automatic file naming would be a great addition for documentation and product research. Great work!
The privacy friction here is genuinely compelling. Most screenshot tools still make people nervous because they either require an account, send data to servers, or embed tracking pixels. The traditional path means either using proprietary tools from Microsoft or Chrome, accepting that your private dashboards are being monitored somewhere. OpenScreenShot removes that friction entirely by being completely local - no accounts, no cloud, no telemetry. Being able to capture sensitive financial reports, internal dashboards, or customer records knowing that everything stays on your machine transforms the trust equation from "maybe" to complete peace of mind. For compliance teams, healthcare professionals, and anyone capturing confidential data, that guarantee of zero server contact is what changes the game from worried to confident.
The "zero data leaves your device" angle is what sold me — for screenshot tools that's rarely verifiable, so MIT-licensing it is the right move. Question: how do you handle lazy-loaded images during full-page scroll capture? I've been scripting WKWebView for batch page renders and found waiting for network-idle isn't enough for below-the-fold content. Curious if you inject scroll events and re-wait, or snapshot viewport-by-viewport.
I like that this combines full-page capture, annotations, and multiple export formats into a single extension instead of requiring several different tools. The PDF export and region capture features look particularly useful for creating tutorials, bug reports, and documentation. Looking forward to trying it in my daily workflow.
