Frequently asked questions

Can I make an image larger as well as smaller?

Yes, though enlarging beyond the original size can look soft since new pixels are interpolated. Shrinking always keeps images sharp.

What are common sizes for social media?

Instagram post 1080×1080, Instagram story 1080×1920, YouTube thumbnail 1280×720, Facebook cover 820×312, X/Twitter header 1500×500, profile pictures usually 400×400.

Does resizing keep transparency?

Yes — PNG images keep their transparent background. JPG output uses a white background because the JPG format has no transparency.
