GAL to TXT Converter

GAL to TXT Conversion Explained

Converting .GAL to .TXT transforms a binary pixel art file into plain text characters. Users perform this conversion to generate ASCII art, extract raw pixel color data (hex codes), or dump file metadata.

You gain extreme compatibility, as any device can read a text file. However, you lose all graphical fidelity, layer structures, animation frames, and alpha channel transparency. The main trade-off is sacrificing visual image data for machine-readable or text-representable data. If you want to view or share the pixel art as a standard image, this conversion is a bad idea. You should convert to .PNG or .GIF instead.

Typical Tasks and Users

This conversion serves specific technical and creative workflows:

• Game Developers: Extracting color palettes, hex codes, or collision map data from pixel art into a readable text format for game engines.
• Technical Artists: Generating ASCII art from pixel art assets for terminal-based interfaces, text-based games, or code comments.
• Archivists: Dumping metadata, layer names, or frame timings from legacy GraphicsGale files into searchable text logs.

Software & Tool Support

Directly converting .GAL to .TXT is difficult because .GAL is a proprietary format.

• GraphicsGale, the official software by HUMANBALANCE Co., Ltd., opens and edits .GAL files but does not natively export to .TXT.
• ImageMagick can convert images to a text-based pixel dump (using the txt: output format), but it does not support .GAL natively. You must export the file to .PNG first.
• Python developers use libraries like Pillow to map pixel luminance to ASCII characters, but this also requires an intermediate image format.

Pros and Cons of the Conversion

Pros:

• Universal Compatibility: Every operating system includes a native text editor (like Notepad or TextEdit) that can open .TXT files.
• File Size: Text files containing ASCII art or hex dumps are extremely small.
• Code Integration: Plain text is easy to parse with scripts or embed directly into source code.

Cons:

• Total Visual Loss: The original pixel grid is destroyed. ASCII art is a highly degraded representation of the original image.
• Loss of Animation: .GAL files often contain multiple animation frames. A standard .TXT conversion usually only captures the first frame.
• Loss of Layers: All layer data, blending modes, and transparency are flattened or discarded.

Conversion Difficulties & Why Convert.Guru

The primary technical problem in this conversion is parsing the proprietary .GAL binary structure. A converter must read the file header, extract the flattened image data from the correct frame, and then apply a conversion algorithm. If generating ASCII art, the converter must map pixel luminance to a specific character set (such as @%#*+=-:.) while correcting the aspect ratio, since text characters are rectangular rather than perfectly square pixels. If generating a data dump, it must map exact X/Y coordinates to hex color values.

Convert.Guru handles this conversion accurately. It parses the .GAL file directly without requiring you to manually export to an intermediate format. It extracts the primary image data and applies a precise mapping algorithm to output clean, structured .TXT files, whether you need ASCII representation or raw pixel data.

GAL vs. TXT: What is the better choice?

Which format should you choose?

Choose .GAL when you are actively drawing, editing, or animating pixel art. It preserves your layers, palettes, and frame timings.

Choose .TXT only if you specifically need an ASCII art representation for a text interface, or if you need a raw dump of pixel color values for a programming script.

Avoid this conversion entirely if your goal is to share the image on the web, use it in a standard game engine, or send it to another artist. For those use cases, convert the .GAL file to .PNG (for static images) or .GIF (for animations).

Conclusion

Converting .GAL to .TXT makes sense only for niche programming tasks, metadata extraction, or ASCII art generation. The biggest limitation to watch for is the complete destruction of the original image's visual fidelity, layers, and animation. Convert.Guru provides a reliable solution for this exact conversion by bypassing the need for intermediate software, directly translating proprietary pixel data into accessible plain text.
