The basics
Large images slow down websites, blow up email attachments and fill up your storage. Compressing removes invisible details and unneeded data, and the file often shrinks by more than half.
What it's for
- Send photos by email or messenger
- Prepare images for your own website or shop
- Save space on your phone or in the cloud
Good to know
- For photos, 70 to 80 % quality is a good balance
- Keep images with text or graphics as PNG
- If an image is already optimal, you simply keep the original
