Frequently Asked Questions
Will compression hurt quality?
Compression changes JPEG quality and may reduce dimensions. Review the result; if the size target cannot be reached, export a smaller image yourself.
When does compression occur?
Choose Fix images in the channel preview before publishing or scheduling. The repaired result is checked again.
Can I choose a quality level?
The repair uses a bounded quality and size adjustment. For precise quality control, export the image in your own editor and upload it again.
Which formats work best?
For photos, JPG/WebP typically produce the smallest sizes; graphics may perform better as optimized PNG or WebP.
