Everything a screenshot needs, in one place.

Tools that other extensions split across half a dozen products, unified in a single fast, private interface.

  • Region capture, instantly

    Hit Alt+Shift+S anywhere, drag a rectangle, and the cropped pixels land in the editor. No tab-juggling, no clipboard dance, no temp files.

  • Smart resize, no pixelation

    Hand-tuned presets for every social network and a multi-step downscaler that keeps detail sharp where one-shot canvas resizers fall apart.

  • Beautiful backdrops

    Drop your screenshot on curated photo wallpapers, eight hand-picked gradients, or any solid color. Tune inset, corner radius, shadow.

  • Format conversion + compression

    PNG, JPEG, WebP — toggle the format, drag the quality slider, watch the file size estimate update live before you save.

  • Batch in, ZIP out

    Drop a folder of images. Apply the same settings to all of them. Get back one neatly named ZIP. No queue, no server, no waiting.

  • 100% on-device

    Every pixel is processed in your browser on your machine. Nothing is uploaded, no accounts, no analytics, no telemetry. Ever.

Workflow

Three steps. No friction.

From screen to share-ready in under thirty seconds — without ever switching tabs or signing in.

  1. STEP 01

    Capture or drop

    Hit Alt+Shift+S to drag a region on any tab, right-click any image and pick "Open in Screenit", or just drop a file onto the editor.

    Drag · Drop · Paste
  2. STEP 02

    Resize or beautify

    Pick a social preset, type exact pixels, or jump to the Backdrop tab and drop your shot on a stunning gradient or photo wallpaper.

    16 presets · 8 backdrops · 8 gradients
  3. STEP 03

    Save it

    PNG, JPEG, or WebP. One file or a batched ZIP. ⌘S to download. Done in seconds, never uploaded.

    PNG · JPEG · WebP · ZIP
Pro tip: hold Space in the editor to peek at the original.
Made for

Anyone who ships visual work.

Screenit replaces the scrappy chain of screenshot tool → Preview → online resizer → upload-to-Slack with one keyboard shortcut.

For developers

Document, demo, ship

Drag-rect over a UI bug, type Alt+Shift+S, drop on a dark gradient, ⌘S — it's in your PR description before the next coffee sip.

  • Keyboard-only workflow
For e-commerce

Resize to every marketplace

Amazon, Etsy, Shopify, eBay — each demands its own dimensions. Drop the product shot, switch presets, batch-export the lot.

  • Batch ZIP download
  • WebP for 70% smaller files

For teams

Polish without Photoshop

Make every doc, deck and Slack thread look like a senior designer prepped it — even when nobody on the team has Photoshop installed.

  • Hold space to compare
  • On-device privacy
  • Zero learning curve
Privacy first

Your screenshots never leave your machine.

Other tools "process for you" in the cloud and quietly retain a copy. Screenit runs entirely in Chrome's sandbox — every capture, crop, resize, and backdrop is computed in your browser, on your device. No server, no upload, no logs.

FAQ

Questions? Answers.

Is Screenit really free?
Yes, completely. No accounts, no trials, no ads, no paywalls. Everything described on this page works the moment you install the extension.
Where do my images go?
Nowhere. Every operation — capture, crop, resize, backdrop, format conversion — runs in your browser on your device. Screenit has no server.
What image formats does it support?
Input: PNG, JPEG, WebP, AVIF, GIF (and anything Chrome can decode as an image). Output: PNG, JPEG, or WebP with a quality slider and live file-size estimate.
Can I batch resize a whole folder?
Yes. Drop multiple files into the editor, apply your settings once, and download every result as a single ZIP with sensible filenames.
Why does it ask for access to all websites?
So the "Open in Screenit" right-click menu can fetch the original image bytes from CORS- or hotlink-protected hosts (Instagram, Pinterest, etc.). All requests are initiated by Screenit's own tab — nothing runs on the pages you browse.
Does the region capture work on chrome:// pages?
Chrome blocks extensions from injecting scripts onto chrome://, the Web Store, and a handful of internal pages. Everywhere else, it works.
Does it work on Edge, Brave, or Arc?
Yes — any modern Chromium browser that supports Manifest V3. Firefox support is on the roadmap.
How do I uninstall it?
Right-click the Screenit icon in the toolbar and choose "Remove from Chrome". No leftovers, no traces.
