About change aspect ratio

Change Aspect Ratio is part of the PixelDesk basic editing collection. Recrop to 1:1, 4:3, 16:9, 9:16 and more. Everyday corrections — cropping, rotating, watermarking, metadata and background clean-up — without installing an editor.

Because everything is processed locally, change aspect ratio works instantly even on large files, keeps full quality until you choose to compress, and never stores a copy of your picture. There is no queue, no sign-up and no daily limit.
