Frequently Asked Questions
How do I change the aspect ratio of a photo?
Upload the photo, pick a size (9:16, 4:5, 1:1, 3:4, 4:3, 2:3, 3:2, 16:9, 21:9), choose how the new frame is filled and download the result. The guest try uses Fill with AI; after sign-up the app also has Crop, Blur fill and custom sizes.
Fill with AI, Crop or Blur fill: which should I pick?
Fill with AI keeps your whole photo and generates new background around it. Crop keeps the whole frame full and cuts away what does not fit, and you choose which part stays. Blur fill keeps the whole photo, sharp and uncut, over a blurred copy of itself, with nothing generated.
Can I set my own width and height?
Yes, in the app after sign-up: type any width and height (64 to 8192 pixels per side, under 25 megapixels). The guest try on this page uses the preset sizes.
Does it change the people or objects in my photo?
No. Fill with AI generates new pixels only outside your original frame and is built to leave the photo as it is; the prompt forbids new subjects, text, logos and watermarks. Crop and Blur fill generate nothing.
What does it cost?
Free guest try: one Fill with AI, no account and no card. After that, from 1 credit per edit with a credit pack: Fill with AI 2 credits, Crop 1 credit, Blur fill 1 credit. No subscription required.
Which shape for which place?
9:16 suits Stories, Reels, TikTok and Shorts, 4:5 and 1:1 suit feed posts, and 16:9 or 21:9 suit widescreen, YouTube thumbnails and banners. You can change the same photo to several sizes, one run each.
