Frequently asked questions
What is the best image size for websites and blogs?
For hero images, 1600–1920px wide is common. For content images, 800–1280px wide with JPG/WebP quality 70–85 balances quality and speed.
How do I reduce image file size without losing much quality?
Resize to the display width you need, then export to JPG/WebP with quality 70–85. Use PNG only when you need transparency or crisp UI assets.
Which mode should I use — Fit, Cover, or Pad?
Fit keeps the whole image inside the box. Cover fills the box (cropping excess). Pad keeps the whole image and adds padding using the selected color.
Does JPG or WebP support transparency?
JPG doesn’t support transparency. WebP and PNG both do. Choose WebP/PNG when you need transparent backgrounds.
