When should you compress images?

Compress images when smaller files make uploading, loading, sharing, or storing them easier.

Compress images before uploading them to a website, online store, blog post, or landing page. Smaller JPG, PNG, and WebP files help pages load faster, improve user experience, and make site assets easier to manage.

It is also useful before sending email attachments, posting to social platforms, saving space on your device, or uploading images through slower connections. In those cases, reducing image file size helps you move files faster without making them unusable.
