I Paid $30/Month for Xnapper — Then Built a Free Alternative in One HTML File

I wasted $360 on Xnapper last year. $30/month for a macOS app that adds pretty backgrounds to screenshots.

Then I realized: it's just CSS gradients and canvas drawing. No server. No account. No subscription.

So I built Screenshot Beautifier — a free, client-side alternative that runs in any browser.

The Problem

Xnapper is great at what it does. But:

$30/month — that's $360/year for a tool that manipulates pixels
macOS only — Windows and Linux users are out of luck
Upload required — your screenshots go to their servers
Account wall — create an account just to beautify a screenshot

What I Built

Screenshot Beautifier does the same thing, differently:

Free demo — drag a screenshot, add a background, export. Done.
$9 one-time for HD export — cheaper than ONE month of Xnapper
100% client-side — your screenshots never leave your browser
Works everywhere — Chrome, Firefox, Safari, Edge on any OS
No account — just open the URL and go

How It Works

It's surprisingly simple. The entire app is one HTML file with inline CSS and JavaScript:

Drag & drop — loads the image into a hidden <img> element
Canvas API — draws the screenshot onto a canvas with your chosen background, shadow, and frame
Export — canvas.toBlob() downloads the result as PNG

The device frame presets (macOS window, browser window, phone) are just rectangles drawn on canvas before the screenshot. The blur backgrounds use CSS backdrop-filter on the canvas element.

Zero libraries. Zero dependencies. One HTML file.
