why does the text look blurry when i edit it in jpeg?

Text looks blurry when edited in JPEG due to lossy compression which causes degradation of image quality each time the image is saved.

JPEG is a format that compresses images by simplifying the color information, which is especially noticeable around sharp edges like text. Each time you save a JPEG, this compression is reapplied, compounding the blur effect around text edges. This makes JPEG less suitable for text-intensive images where clarity and precision are required.

To avoid this, consider using PNG or WebP formats which support lossless compression, preserving the quality of text across edits. Tools like EditTextImage allow you to process images and preserve text sharpness by editing in these formats. Adobe Photoshop and Photopea also offer lossless editing capabilities, though they may require more manual effort in preserving font characteristics and quality.

For precise text rendering, it's crucial to choose the right format and tool. PNG preserves the exact pixel data, preventing the blurry appearance caused by JPEG compression. This choice ensures your text remains crisp, especially if you're making multiple edits or working with small text sizes.
