why does my edited jpg look blurry?

Blurriness in an edited JPG can result from lossy JPEG recompression artifacts, which degrade image quality each time the file is saved. JPEG uses a compression method that reduces file size by discarding some data, and repeated saves amplify this effect.

When editing text in JPEG images, consider using tools like EditTextImage that return results in 2K resolution, minimizing visible degradation. During the editing process, opting for formats like PNG can help preserve quality as PNG does not compress using lossy algorithms, thus avoiding the incremental quality loss associated with JPEG.

Another approach is to work in a higher resolution than needed and downscale the image as the final step, which can help soften the impact of any artifacts introduced during editing. If you are using software like GIMP or Photopea, make sure to adjust the compression settings to the lowest possible level while saving.

If blurriness persists, it may also be due to resizing the image without maintaining the aspect ratio or not using a tool that properly aligns pixel data, like the tool, which uses bounding-box-conditioned generation to maintain text clarity.
