why does edited text in images sometimes look blurry?

Edited text in images can appear blurry due to lossy JPEG recompression artifacts, which degrade image quality every time a JPEG is edited and saved.

JPEG is a commonly used format for images, but it uses lossy compression to reduce file sizes. This means that every time you edit and save a JPEG, some data is lost, and the quality deteriorates. Text, in particular, can become fuzzy or pixelated since sharp edges of letters suffer most from the compression algorithms.

To avoid these issues, consider using PNG format, which employs lossless compression, preserving the clarity of text and graphics even after multiple edits. PNG also supports an alpha channel for transparency, which can be beneficial if you're layering text over different backgrounds repeatedly.

Alternatively, tools like EditTextImage are optimized to handle these issues more effectively, allowing you to edit text without noticeable degradation in quality. They also support direct editing in PNG format, which is ideal for maintaining high-quality text renderings.

Switching to or saving your work in a format that supports lossless compression from the start can significantly improve the visual quality of text in edited images.
