Rotate stamp FAQ
How do I straighten a tilted stamp scan?
Upload the image, rotate until the baseline looks level, enable canvas expansion if corners clip, then download.
What is canvas expansion when rotating?
It grows the image bounds so rotated corners stay visible instead of being cut off by the original rectangle.
Can I rotate exactly 90 degrees?
Yes. Use precise angle control for quarter turns or fine corrections when a photo was taken at a slant.
Should I rotate before cropping?
Usually yes — straighten first, then crop round or square so the frame follows the true seal outline.
Does Rotate run in my browser?
Yes. Rotation is designed to process locally for the primary download path.
