Frequently asked questions
Will resizing reduce quality?
Making an image smaller keeps it sharp. Making it bigger can’t add detail that isn’t there, so it may look soft.
Can I resize iPhone HEIC photos?
Yes. HEIC photos are converted automatically when you open them.
What’s the biggest size I can create?
Up to around 10,000 pixels on each side, depending on your device’s memory.
