Frequently Asked Questions
What image formats can I resize? +
You can resize any image format your browser supports, including JPG, PNG, GIF, WebP, BMP, and SVG. The resized image is downloaded in PNG format by default to preserve quality.
Does resizing reduce image quality? +
Enlarging an image beyond its original dimensions can reduce quality because new pixels must be interpolated. Shrinking an image generally preserves quality well. For best results, start with the highest resolution source image you have.
What does 'lock aspect ratio' do? +
When aspect ratio is locked, changing the width automatically adjusts the height (and vice versa) to keep the image's original proportions. This prevents your image from looking stretched or squished.
Is my image uploaded to a server? +
No. All image processing happens entirely in your browser using the Canvas API. Your images never leave your device, making this tool completely private and secure.
