Capture
Open KoalaShot and capture the complete vertical page, not just the visible viewport.
Full-page screenshot for your browser
Capture the whole page.
Capture a full vertical webpage, redact sensitive details, and copy or save the PNG. Free, open source, and processed entirely on your device.
Simple by design
Capture, edit, and keep it local.
KoalaShot scrolls through the current page, captures each viewport, and stitches the sections into one vertical image. Choose your output before capture. A completed original remains available while the popup stays open.
Edit if needed
Capture & edit opens the local editor before any export. Crop, annotate, and use opaque Redact for sensitive details. Blur and pixelation are cosmetic.
Copy or save
Export your edited PNG. Need the untouched original? Capture & copy and Capture & save go directly to their destination without opening an editor.
Inside the editor
Make your point clear.
Add arrows, highlight a detail, crop the page and export your PNG. Every edit stays in your browser.
Privacy first
Your screenshot stays with you.

- No accounts or uploads.
- No tracking, telemetry, cookies, or history.

Questions
FAQ
Does KoalaShot upload screenshots?
No. Capture, stitching, clipboard operations, and temporary editor storage are local browser operations.
Can it capture every page?
Normal document scrolling is supported by default. The popup can also capture the largest fully visible vertical scroll area inside a page. Browser-protected pages, partially off-screen roots, and horizontal stitching remain unsupported.
What can the editor do?
The local editor supports pen, highlighter, arrows, lines, rectangles, ellipses, multiline text, secure opaque redaction, cosmetic pixelation and blur, numbered markers, crop, selection, movement, undo/redo, zoom, pan, and edited PNG copy/save.
Where are store links?
Official installation and review links appear separately for each browser when its listing is configured. See Browser store availability above for the current links. GitHub provides builds and installation instructions in the meantime.
