User reviews

Keep your images proportional.

I am constantly resizing pictures for frames. It makes it so easy when you know the exact measurements you’re working with and where you need to make editing decisions.

Great app!

I use this to scale down. If I have a 30x40 canvas, what size should my sketch be in order to keep it to scale? This app is quick and easy to use! In the studio or out in the field. It’s absolutely great for what I use it for! Still love this app! I also now use it to scale up. If I’ve painted something small and want to blow up to large canvas but keep the scale, what size canvas do I need to buy? Works great!!

A great app becomes even better

I work for a blueprint company and sign shop. We are always looking at size limitations imposed by the customers. This is the best answer to all the "what if it was" questions. Also the customer and I can see quickly how pixilated an image would become if it gets blown up too big without expensive graphic software. Some software developers go above and beyond, thank you for adding this great feature to an already amazing app.

THIS IS THE BEST APP FOR SIZING IMAGES

I've usually only,done reviews when prompted but I saw this only has 13 reviews when I went to reinstall it and HAD to review it because it is my GO-TO app to resize anything. It's SIMPLE EASY TO USE AND WORKS IN A SNAP! I can't believe it's only got 13 reviews, I've been using it for years and will never use anything else.
