To share a screenshot on social media, crop it to the part that makes your point, hide personal details, add a frame, and export it at a size that stays sharp. In OpenScreenShot, use Crop to trim, Blur with the Solid fill to hide details, and the Frame panel for padding, rounded corners, a shadow, and a background. Then export a PNG at 200 % or at an exact pixel width.

Prepare a screenshot for a post step by step

  1. Capture the page. Selected Region or Capture element in the right-click menu gives a tight image from the start.
  2. In the Editor, select Crop (C), drag over the part you want to keep, and click Apply.
  3. Select Blur (B), choose Solid under Hide area, and cover names, profile pictures, email addresses, and anything else that is not yours to share.
  4. Click Frame in the top bar. Choose a Preset, then adjust Spacing, Corners, Shadow, and Background.
  5. Click Save image. In the Export dialog, choose PNG and set Scale to 200 % or to an exact width.
  6. Open the saved file and check the redactions and the frame before you post it.

To post without a saved file, click Copy or press Ctrl+C (⌘C on macOS) and paste the image into the post. The frame is included in the copied image.

Hide personal information first

Do the redaction before the frame and the export, and check it again in the saved file. Comments, follower names, notification counts, browser tabs inside the page, and account menus often show more than you intend.

A soft blur or a mosaic can leave clues about short text. Solid covers the area completely in the export. The redaction guide explains how to cover an area with a margin and how to check the result.

Choose a frame

The Frame panel, called Beautify in the documentation, has six presets:

  • Clean: a simple frame with a soft shadow
  • Airy: extra space around the screenshot
  • Snug: a close-fitting frame
  • Flat: square corners with no shadow
  • Poster: rounded corners with a deep shadow
  • Cutout: a shadow with no background

After you choose a preset, the sliders let you change the spacing, the corner radius, and the shadow. For Background, choose one of six gradients (Ink, Coral, Dusk, Mint, Sand, Sky), a solid color, or Transparent. The frame previews live and goes into every export.

A transparent background needs PNG or WebP. JPEG has no transparency, so it fills the background with a solid color.

Export at a sharp size

Under Scale, choose 25, 50, 100, or 200 %, or type an exact pixel width. A capture of a small region can look soft when a site enlarges it in a post; 200 % gives the site more pixels to work with. A size past Chrome’s canvas limit is refused, and the dialog tells you instead of saving an empty file.

PNG keeps interface text sharp. JPEG and WebP have a quality control for smaller files. Each social site has its own size and compression rules, so check the post preview before you publish.

Arrows and labels

Add one Arrow (A) or a short Text (T) label when the point of the image is not obvious at a glance. Spotlight (O) dims everything outside one area, which works well for a single feature in a busy interface. Keep annotations few, because a post preview is usually small.

Limits

The extension captures the page content only. It does not include the browser toolbar or your desktop. Captures and edits stay on your computer until you post or upload the image; the site you post to has its own storage and sharing rules.

The export reference lists every format. For screenshots that teach a task, see screenshots for documentation. For a short video of your product, see product demo videos.
