I found a fantastic resize app called image size and so far I’ve been able to resize my iPhone 11 Pro Max photo files up to 33mp. I haven’t gone any higher as there’s no need. But 24 or 33 mp works fine. What do you think of the clarity of this image set at 32.9mp? I’m very impressed at the enlargement with no loss of details or quality. If you print images from the iPhone, this is the app to get!
Added another 33mp image. The small details are very clean. Moment 58mm was used on these images. The upload probably decreases IQ on these.
