Frequently Asked Questions
Is the image resizer free?
Yes, free users get 5 resizes per day. Pro users get unlimited.
What image formats are supported?
JPG, PNG, and WebP formats are supported.
Can I resize by percentage?
Yes. Switch to Percentage mode and use the slider from 10% to 200% of the original size.
Does locking the aspect ratio keep my image from distorting?
Yes. When aspect ratio is locked, changing width automatically updates height and vice versa, so your image won't be stretched or squished.
Is my image uploaded to your servers?
No. Resizing happens entirely in your browser — your image never leaves your device.
What is the maximum file size?
Free users can resize images up to 10MB. Pro users up to 50MB.
Why Use ToolSnap's Image Resizer?
ToolSnap's Image Resizer processes files entirely in your browser using the HTML5 Canvas API — nothing is ever uploaded to a server. You get precise control with two resize modes: enter exact pixel dimensions with aspect ratio lock to prevent distortion, or use the percentage slider for quick scaling. The result is exported as a high-quality JPEG with no watermarks and no signup required.
