Frequently Asked Questions
How do I keep my photo from stretching?
Make sure the "Lock Aspect Ratio" box is checked. When locked, changing the width will automatically update the height (and vice versa) to keep your photo in its original proportion.
What is the difference between pixels and percentage?
Pixels let you change the image to an exact size (like 1200 x 800). Percentage scales the image relative to its current size (like making it 50% smaller or 150% larger).
Can I resize many photos at once?
Yes, you can upload multiple photos in bulk mode. They will all be resized to the same dimensions or scale, and you can download them as a ZIP file.
Does resizing reduce the quality of my photos?
Shrinking a photo will make it smaller in file size but keep it sharp. However, blowing up a very small photo to a huge size might make it look blurry or pixelated, as the computer has to guess the missing details.
