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
Full-page screenshots,
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.
+ the entire page, top to bottom
+ retina pixels, exactly as rendered
– no watermark, no account, no upload
// 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.
DPR 2.0 / HDAnnotate it
Arrows, lines, rectangles, ellipses, freehand pen, text, and a highlighter — with a palette and stroke control.

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.

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.

// how it captures
One engine, engineered to get the whole page right.
Walks the page, seams it whole
Steps the page one viewport at a time and seams the frames together into a single image. Uses only activeTab — no debugger banner, no extra permission to grant.

Sharp, and steady on tricky pages
Samples at your display's device-pixel ratio for crisp text, neutralizes fixed and sticky headers and full-height sidebars so nothing repeats, and waits for lazy-loaded content before it captures.

Your screenshots never leave your machine.
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.

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 or $99 lifetime.
Nowhere but your downloads folder. Everything happens locally in your browser — there
is no server to upload to, no account, and no extension 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. On pages with
tricky lazy-loading or canvas content, it waits for content to settle and neutralizes
fixed elements before stitching, so the capture stays clean.
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.
Capture and export are free. Pro unlocks the editor for crop, annotation, and
redaction. Choose Pro — $24/yr (about $2/mo) — or a one-time $99 lifetime license
through Polar; activate your license key in Settings, and it's honored offline for up
to two weeks at a time. Cancel subscriptions anytime.
