PNG vs JPEG vs WebP: Differences and Best Uses

Image formats differ in more than their file extensions. Choosing the right format for a photo, logo, or screenshot can reduce file size while preserving quality.

Steps to convert

  1. Load the original image and check the pixel dimensions and presence of transparency.
  2. Set the output format, image quality, and resizing dimensions if necessary to suit your needs.
  3. Compare the output file size and preview.
  4. Enlarge and check the text, thin lines, and transparent parts, then save it under a different name.

Guidelines for choosing a format

WebP is the first choice for photos on web pages, and JPEG is also available if compatibility is required. For logos and UI images, PNG or WebP are suitable as they can maintain transparency and outlines.

BMP is largely uncompressed and often produces large files. Unless you need it as an interchange format or for compatibility with an older system, consider converting it to PNG or another suitable format.

Even if you change only the image extension, the format will not change. Be sure to use the image conversion function to save in the desired format.
