What is image compression?
Image compression reduces the amount of data needed to store an image. A smaller image file can be easier to upload, share and store. The amount of savings depends on the original format, image dimensions, content and selected quality.
JPG, PNG and WebP compression
JPG is commonly used for photographs and other images with many colors. PNG is useful when lossless image data or transparency is important. WebP can provide compact files for many modern web images. The best format depends on how the image will be used and whether transparency needs to be preserved.
When should you compress an image?
- Before uploading images to a website to reduce page asset size.
- Before attaching large images to email or messages.
- When preparing images for online forms with file-size limits.
- When organizing a photo or design collection to save storage space.
- When sharing images where a smaller file is more convenient.
