Frequently Asked Questions
Will resizing reduce image quality?
Scaling down preserves quality well. Scaling up (making an image larger than its original) will result in some blurriness since new pixels must be interpolated. For best results, start with the highest resolution source image you have.
What does "lock aspect ratio" do?
When locked, changing the width automatically adjusts the height (and vice versa) to maintain the image's original proportions. Unlock it if you need to stretch or squish the image to exact dimensions.
Is my image uploaded to a server?
No. All resizing happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device.
Can I change the output format?
Yes. You can output the resized image as JPEG, PNG, or WebP regardless of the original format. This is useful for converting formats while resizing.
