After enhancing an image, which compression format is most suitable?

The most suitable compression format after enhancing an image is lossless compression. This is because lossless formats retain all the original data and quality of the image, ensuring that no information is lost during the compression process. After enhancing an image, such as adjusting colors, brightness, or sharpness, preserving the integrity of those adjustments is crucial. Lossless compression allows for the enhancement details to remain intact, making the image suitable for further editing or printing.

In contrast, lossy compression reduces file size by permanently eliminating some data, which can compromise the quality of the enhancements made to the image. JPEG is a commonly used lossy format that may not be ideal if the goal is to maintain the highest quality after making modifications. While PNG is also a lossless format and could be suitable, the broader term "lossless" encompasses various file formats, thus emphasizing the importance of choosing a compression method that guarantees quality retention after enhancing the image.
