Yes — resizing happens entirely on your device using your browser's canvas. Your image is never uploaded to any server, which also makes it faster than upload-based tools.
Frequently asked questions
Will resizing reduce quality?
Shrinking an image keeps it sharp. Enlarging beyond the original size can look soft — for big enlargements you'd want an AI upscaler.
Is there a watermark?
No watermark, no sign-up, no limits.
