Quality
For web use, it is generally appropriate to set the quality to around 70-90%. This allows you to maintain a small file size while minimizing visual loss. Adjust the quality while checking the preview image and estimated conversion file size.

Edit Image
PNG files are widely used raster image file formats on the internet, known for their 'lossless' characteristic. This means that the quality remains undistorted when compressed while maintaining a certain pixel count. Hence, they are ideal for storing high-quality images such as logos, photos, and screenshots, and also support transparency, making them useful for creating web graphics with transparent backgrounds.
JPG, short for Joint Photographic Experts Group, is a standard format for compressing and storing digital images. Widely used for photographs and web images, it maintains a certain level of image quality while reducing file size. It primarily uses Discrete Cosine Transform (DCT) for image compression, which helps reduce file size and save storage space. However, some information may be lost during the compression process. JPG is supported by most image viewers and editing programs, making it very convenient for online image sharing. However, it does not support transparency and may not be suitable for images with sharp details or text.
The advantage of converting PNG to JPG is that JPG can greatly reduce file size using lossy compression. Therefore, it improves the loading speed of web pages and saves bandwidth. Additionally, JPG is suitable for photos and images, with less color distortion or degradation in image quality. However, since JPG uses lossy compression, increasing the compression ratio may degrade image quality. Particularly, for images with text or sharp details, noticeable quality loss may occur after compression. Also, JPG does not support transparency, and increasing the compression ratio can degrade image quality, so caution is advised. Users should choose the appropriate compression ratio and quality based on the nature and purpose of the original image.
