What This Tool Does​

What the tool does​

Image Comparison Creator lets you upload two images and combine them into a single side-by-side comparison with a configurable label. Choose from:

  • Before / After - with localized text in 11 languages (EN, UK, ES, ZH, HI, FR, AR, PT, DE, JA, KO)
  • VS - a bold circular badge between images, perfect for head-to-head battles
  • Now / Then - for progress tracking and throwback comparisons
  • Custom - type any left and right label text you need

What problems it solves​

Eliminates the need for complex image editors (Photoshop, GIMP, Canva) just to create a simple side-by-side comparison. Everything runs in the browser with no account needed.

Who should use it​

Marketers, social media managers, content creators, photographers, fitness coaches, designers, and educators who regularly need to produce side-by-side comparison images.

Why it matters​

Visual comparisons drive engagement. This tool lets anyone produce them in seconds, in any language, for any purpose - completely free and private.

How It Works​

Input​

Upload two images (JPEG, PNG, WebP) via drag-and-drop or file picker. Select a label mode and, where applicable, a language or custom text.

Processing​

The canvas-based renderer combines your images and overlays the chosen label entirely in your browser using the HTML Canvas API.

Output​

A PNG download containing both images side-by-side with your chosen labels. Filename is auto-stamped with a timestamp.

Limitations​

Designed for simple side-by-side layouts. For best results, use images with similar aspect ratios. Very large images may process slower on low-end devices.

Frequently Asked Questions​

What label modes are available?​

Four modes: Before / After (multi-language), VS (circular badge), Now / Then, and Custom (type any text for left and right labels).

Can I use my own language for the Before/After labels?​

Yes. The Before/After mode supports 11 languages: English, Ukrainian, Spanish, Chinese, Hindi, French, Arabic, Portuguese, German, Japanese, and Korean. For other languages, use Custom mode and type any text you like.

Can I customize the "VS" badge color?​

The VS badge uses a dark (#333) circle with a white outline to contrast against most image backgrounds. Color customization may be added in a future update.

Is my data sent to a server?​

No. All image processing runs locally in your browser via the HTML Canvas API. No images or data are ever uploaded.

What image formats are supported for input?​

JPEG, PNG, and WebP. The output is always a PNG.

Does it work on mobile?​

Yes, the tool is fully responsive. For the best experience, use a desktop or laptop where file management is easier.

Is there a limit on image size?​

No strict limit, but images taller than 500 px are automatically scaled down for display. The output resolution reflects the actual uploaded image dimensions (scaled proportionally).

Can I use the downloaded image commercially?​

Yes - you own the output. The tool adds no watermarks.
