Why compress images?
Large images fill up inboxes, storage and web pages. Here's what changes when you make them smaller.
Smaller files that still do the job
Compression strips out data your eyes are unlikely to notice, so an image takes up less space but still works for sharing, the web and documents.
- Easy to email. Attach more photos without running into attachment limits.
- Lighter web pages. Smaller images help your pages load faster for visitors.
- More room on your device. Free up storage on phones, laptops and shared drives.
What is image compression?
Image compression reduces the file size of a picture by removing data it doesn't need and storing the rest more efficiently. The image keeps its dimensions and looks much the same, but the file is lighter to store and share.
