Tool Introduction

This tool can convert any image into ASCII art with one click. It supports real-time adjustments for brightness, contrast, blur, dithering, edge detection, and offers multiple character-set styles. The result can be copied as plain text or exported as a PNG image, making it easy to use on social media, in documents, or as code comments.

Usage Help

1. Upload Image

Click the "Upload File" button on the left and select a PNG, JPG, or GIF image. The tool will immediately load and display it as ASCII art.

2. Basic Adjustments

• Output Width: Controls the number of characters per line; larger values yield wider output and larger files.
• Brightness: Drag left to darken, right to brighten—changes apply instantly.
• Contrast: Increases or decreases the difference between light and dark areas.
• Blur: Slight blur reduces noise, but too much will lose detail.
• Invert Colors: Swaps black and white—useful for dark backgrounds.

3. Dithering Options

Dithering smooths grayscale transitions and reduces banding.

• Floyd–Steinberg: Classic error-diffusion for fine, subtle results.
• Atkinson: Mild dithering that retains more detail.
• Noise: Random noise for a stylized look.
• Ordered: Ordered dithering with a clear pixel-art feel.

4. Character Sets

• Detailed: Uses 70 levels of grayscale characters for rich depth.
• Standard: Uses 10 common characters for compact output.
• Blocks: Uses block characters, ideal for low resolution.
• Binary: Only 0 and 1 for a minimalist style.
• Hex: Uses 0-F to represent grayscale—retro digital vibe.
• Manual: Enter any single custom character.

5. Edge Detection

Converts the image into line-art style.

• Sobel: Extracts prominent edges with adjustable threshold.
• DoG (Contour): Creates hand-drawn-like outlines with adjustable thickness.

6. Display Settings

Drag the "Zoom" slider to enlarge or shrink the ASCII art for detailed inspection or an overall view.

7. Saving Results

• Copy ASCII Art: One-click copy to clipboard; paste directly into chat apps or text editors.
• Download PNG: Renders the current ASCII art as a PNG image and downloads it.

8. Reset

Click "Reset All Settings" to instantly restore default values and start fresh.

FAQ

• Image too large? Resize the image on your computer or phone before uploading, or reduce the "Output Width".
• Garbled output? Use a monospaced font (e.g., Consolas) for proper alignment.
• Formatting broken in WeChat/QQ? Paste into Notepad first, then copy from Notepad to send.
