Why compress images?
Large images slow pages, increase upload times, and take more storage. Compression reduces file size so images are easier to share and upload.
Choose the right format
JPEG is usually a good choice for photographs, while PNG is useful for graphics that need transparency or crisp edges. The best format depends on the image.
Resize before compressing
If an image is much larger than the space where it will be displayed, resizing it first can reduce file size dramatically without visibly hurting quality.
Compress the image
Use a moderate compression level and compare the result with the original. The goal is the smallest file that still looks good for its intended use.
Check the final file
Open the compressed image at its normal display size. If text, edges, or important details look damaged, use a lighter compression setting.
