Capture
It auto-scrolls top to bottom, throttling to stay smooth, and stitches every frame into one image. Fixed headers are neutralized so they never repeat down the page.
Chrome extension · Manifest V3 · 100% local
The whole page,
in one shot.
Auto-scroll any website, neutralize sticky headers, and stitch it into one full-page, retina-sharp screenshot — then crop, annotate, and redact it and export to PNG, JPEG, or PDF. Nothing ever leaves your machine.

the gap
Your browser screenshots stop at the fold. One Shot Screen keeps going — header to footer, in a single stitched image.
Built-in capture only grabs what's on screen. Other tools watermark the result, flatten your layout, or quietly upload it to someone's server. None of that here.

// how it works
Three steps, start to finish.
Click once. Edit if you want. Save the way you need it.
Edit
Crop, cut, draw arrows, type, and highlight — then blur or pixelate anything private. Non-destructive, with full undo/redo and a precise stroke palette.
Export
Save as PNG, JPEG at the quality you pick, or a single or paginated PDF. Every edit bakes in — and redaction is irreversible in the saved file.

Everything you need to ship a clean shot.
A focused toolset — capture that gets the whole page right, an editor that respects your pixels, and exports that just work.
auto-scroll + stitch
Full page, edge to edge
Capture the entire scroll height of any site as one continuous image — or grab just the visible area. Sticky and fixed elements are neutralized so nothing repeats.
Retina-sharp
DPR-aware sampling captures at your display's true resolution — crisp text, no mush.

Redact with confidence
Blur or pixelate anything sensitive. Redaction is flattened into the export — the original pixels are gone in the saved file, not just hidden.

Private by design
No servers, no account, no remote code. Your captures stay on your machine.
Read the privacy promise// one click
It all starts from one click.
Pin One Shot Screen, click the toolbar icon, and pick full page or visible area. Choose your format up front — the rest is automatic.
- Full page or visible area, one button each
- Pick PNG, JPEG, or PDF before you capture
- JPEG quality slider when you want a smaller file
- A keyboard shortcut for capture, too
// two engines
Two ways to capture. Both yours to choose.
Scroll & Stitch
Walks the page one viewport at a time and seams the frames together. Uses only activeTab — no debugger banner, no extra permission.
- activeTab only
- works everywhere
- no banner
DevTools Protocol
Asks Chrome for one pixel-perfect, full-height frame. Opt-in behind a runtime debugger permission you grant from Settings — for the pages that fight back.

One Shot Screen runs entirely inside your browser. There's no backend to send anything to — and Manifest V3 forbids remote code outright, so every library and font ships vendored inside the extension.

// faq
Questions, answered.
Yes. Capturing full pages and exporting to PNG, JPEG, or PDF is free forever. The
editor — annotate, crop, cut, blur/redact — is Pro at $2/month, and a 7-day trial
unlocks it the moment you install, no card needed.
Nowhere but your downloads folder. Everything happens locally in your browser — there
is no server to upload to, no account, and no analytics. Manifest V3 forbids
remote code, so the extension literally can't phone home.
On the vast majority, yes. Very tall pages are capped at the browser's maximum canvas
height (about 32,767px) — One Shot Screen guards against that gracefully. For pages
with tricky lazy-loading or canvas content, switch to the DevTools Protocol engine in
Settings for a pixel-perfect single-pass capture.
Scroll & Stitch (the default) uses only the
activeTab permission, shows no debugger banner, and works on essentially
every page. DevTools Protocol asks Chrome for one perfect
full-height frame; it's opt-in behind a debugger permission you grant
from Settings, for the rare page the stitcher can't handle.
Yes. Blur and pixelate are flattened into the exported file — the underlying pixels are
destroyed, not just covered. What you redact can't be recovered from the saved image.
Installing starts a 7-day Pro trial automatically — no card, no account. After that,
Pro is $2/month — billed annually at $24/yr — through Lemon Squeezy; you activate your license key in Settings, and
it's honored offline for up to two weeks at a time. Cancel anytime.
