what causes text to look different when pasted from an image?

Text copied from an image may look different when pasted due to the CSS font-family fallback chain, which affects how fonts are rendered across different systems and applications.

When text is embedded in an image, it retains specific styling characteristics such as font weight, size, and type. However, when extracted, typically via OCR (optical character recognition), the text loses these visual attributes and defaults to whatever is available on the target platform. This is often governed by the CSS font-family rule, which dictates a list of fonts to use in priority order if the preferred font is unavailable.

If the extracted text looks different, it might be because the precise font used in the image isn't available on your system, leading it to default to a generic font like Arial or Times New Roman. This can happen frequently when moving across different operating systems or devices with varying font libraries.

To mitigate these discrepancies, use applications or browser extensions that allow you to specify custom fonts for better control over how text appears after extraction. When precise text replication is needed, using a tool like EditTextImage to edit text directly in the image ensures better adherence to the original styling without relying on external font availability.
