why does text look different when copying from an image?

Text appears different when copying from an image due to the CSS font-family fallback chain, which alters the appearance based on available system fonts. This results in discrepancies between the original image text and the copied version.

When text is rendered in an image, it's often with custom fonts or styles that may not be available on your system when you attempt to paste it elsewhere. The system resolves this by falling back to the closest available font, which can lead to noticeable differences in appearance, including variations in weight, kerning, and size.

Further discrepancies can arise from the image format used; for instance, PNGs and JPEGs store text as rasterized pixels, not vectors, meaning they lack inherent font data. Tools like EditTextImage are designed to edit this text directly in the image and can re-render text to closely match the existing style, which is crucial for maintaining consistency.

For projects where text consistency is important, using a text-editing tool that supports advanced font matching, such as the tool, ensures that any modifications preserve the original look as closely as possible. Saving edited images in a high-quality format like PNG ensures minimal distortion, maintaining font integrity throughout your project.
