Common Questions (Q&A):

1. Q: Will resizing affect sharpness?
   A: Yes. Downscaling usually works well, while upscaling can look blurry. Start from a high-resolution source when possible.
2. Q: How do I create the same size for many images?
   A: Upload multiple images, set target width and height, choose the resize mode and format, then export the batch.
3. Q: Are resized images uploaded?
   A: No. Resizing runs locally in the browser, which is useful for product images, avatars, and content assets.
