How to Compress Image
Compressing an image means reducing file size while keeping enough visual quality for the place where the image will be used.
Upload The Original Image
Start with the clearest original file you have. JPG photos, PNG graphics and WEBP images can usually be compressed for faster sharing and publishing.
If the image is very large, resizing dimensions before lowering quality can make the file much smaller without obvious visual damage.
Start With Image Dimensions
Most oversized files come from dimensions that are much larger than the final use. Resize the image before lowering quality so the result stays cleaner.
For websites, a maximum width around 1600 to 2000 pixels is enough for most content images.
Balance Quality And File Size
A quality setting around 70 percent is a strong starting point for JPG photos. Increase it when you see artifacts, and lower it when file size matters more.
Always compare the preview and file size after compression instead of guessing from the slider alone.
Download And Compare
After compression, compare the original and compressed image before using the new file.
Use stronger compression for thumbnails and lighter compression for product photos, screenshots or images with small text.
