Frequently asked questions
Is my image uploaded anywhere?
No. The image is decoded and resized on a canvas inside your browser. Nothing is sent to a server, stored, or logged — close the page and the image is gone.
Cover or Fit — which should I choose?
Cover fills the whole frame and crops the edges (centered), so nothing is stretched and there are no blank bars — best for photos. Fit keeps the whole image and fills the leftover space with your chosen background color — best when cropping would cut off text or a logo.
Will resizing make my image blurry?
Shrinking a large photo to a preset size keeps it sharp. Enlarging a small image beyond its original size cannot add detail, so start from the largest original you have. PNG is best for graphics and text; JPG or WebP at 85% is best for photos.
Why is my transparent PNG on a white background in JPG?
JPG has no transparency, so transparent areas are filled with white on export. Choose PNG or WebP if you need the transparency kept.
Do these preset sizes change?
Platforms adjust their recommended sizes from time to time. The presets here reflect the sizes in common use in late 2026; the Custom size option covers any size a platform asks for next.
