Utilize the Right File Format: JPEG goes well with photographs, but PNG is suitable for graphics containing text or transparency.
Maintain Aspect Ratio: Don't distort images by keeping the original aspect ratio or proportion. Most tools have an option to lock the aspect ratio.
Use Compression Tools if Necessary: For the web, TinyPNG or JPEG Optimizer can compress this size without losing much quality.
