Screenshot Beautifier: a worked example

A plain UI screenshot looks unpolished in a launch tweet and needs a gradient backdrop and window frame.

Input

app.png · gradient background · macOS window + shadow · padding 64
Screenshot Beautifier produces

Output

A polished, social-ready composite around the screenshot

Padding, a rounded window chrome, shadow, and a backdrop give a raw capture the produced look that performs better on social and in decks, without opening a design tool. Presets match common aspect ratios.

Tips & best practices

  • The downloaded PNG and the on-screen preview differ for some frames: the iPhone notch, Android navigation bar, and the Browser 'example.com' address bar show only in the preview and are not exported. Use the Browser or macOS frame if you need the chrome to appear in the file.
  • Because the canvas gradient is redrawn corner-to-corner from the two hex stops, a very wide or tall image can show a slightly different gradient angle than the preview; check the exported PNG, not just the preview.
  • There is no 2x export, the PNG matches your source image resolution plus padding, so start from a high-resolution screenshot if you need a crisp result.
  • The aspect-ratio buttons do not crop the output; crop the screenshot before uploading if you need a specific ratio.

Examples

  • Framed OG image from an app screenshot

    Upload a 1280x800 screenshot, pick the Ocean gradient, keep 64px padding, set radius 16 and shadow 40, and choose the Browser frame. The export is a 1408x928 PNG with a #1f2937 title bar and traffic-light dots, suitable as a social/OG preview.

  • Clean solid-background asset

    Choose the White or Black solid preset (or a custom hex), set the device frame to None, and lower the shadow toward 0 for a flat documentation thumbnail with just padding and rounded corners.

How it works

Screenshot Beautifier composites your image onto a larger HTML canvas with even padding, a soft drop shadow, and rounded corners, then exports the result as a PNG named screenshot-beautified.png. The output canvas is sized exactly to your image dimensions plus twice the padding value (imgWidth + padding*2 by imgHeight + padding*2), so a 1280x800 screenshot with the default 64px padding becomes a 1408x928 file. Padding is adjustable from 16 to 128px (step 8), the corner radius from 0 to 48px (step 4, drawn with quadraticCurveTo and a canvas clip so the screenshot is masked to the rounded shape), and the shadow blur from 0 to 100px (step 5). The shadow itself is fixed at rgba(0,0,0,0.3) with no horizontal offset and a vertical offset of one quarter of the blur value, which lifts the screenshot off the background. Everything runs in the browser via the 2D canvas API; no image is uploaded.

The background comes from eleven built-in presets plus a custom color picker. Eight are diagonal gradients with fixed names and palettes (Ocean #667eea to #764ba2, Sunset, Aurora, Forest, Fire, Night, Sky, Lavender) and three are solids (White #ffffff, Black #000000, Gray #374151). One honest caveat: the gradients are defined in CSS as linear-gradient(135deg, ...), but the canvas export extracts only the two hex stops via regex and redraws them with ctx.createLinearGradient(0, 0, width, height), a corner-to-corner diagonal. The live preview uses the real CSS gradient, so a wide or tall export can show a slightly different gradient angle than the preview. The Randomize button shuffles a preset and picks padding (32-111), radius (8-37), and shadow (20-79) at once, and a Share Config button encodes the current background, padding, radius, shadow, aspect ratio, and frame into the URL so a look can be reproduced.

The device-frame control lists None, Browser, macOS Window, iPhone, and Android, but be aware that the live preview and the exported PNG are not identical. In the export, only the Browser and macOS options actually draw chrome: a 32px-tall #1f2937 title bar with three traffic-light dots (red #ef4444, yellow #eab308, green #22c55e). The iPhone notch, the Android navigation triangle/circle/square, and the Browser preset's 'example.com' address bar appear only in the on-screen preview and are not baked into the downloaded image. The aspect-ratio buttons (auto, 16:9, 4:3, 1:1, 9:16) are likewise presentation-only and do not crop or letterbox the canvas. The tool is purely presentation packaging, frame, padding, shadow, and background, not an annotation or cropping tool, and it always outputs a single full-resolution PNG with no upscaling or 2x Retina option.

Frequently asked questions

Can I use a custom background image?

The tool supports gradient and solid color backgrounds. For custom image backgrounds, compositing tools offer more flexibility.

What device frames are available?

MacBook, iPhone, iPad, Android phone, and generic browser window frames are included.

Related tools and how they differ

  • Meme Generator: Overlays customizable caption text in meme fonts with stroke outlines; use it to write on the image, not to frame or pad it.
  • Image Annotator: Draws editable arrows, shapes, highlights, freehand and text with undo and layers; use it to point out details, not to add a background frame.
