Frequently Asked Questions — Image Resize
Is the resize tool completely free?
Yes, it's 100% free with no limits. No registration, no watermarks, and no file size caps. All processing is done locally in your browser.
What is the maximum image size I can resize to?
The maximum output dimension is 32,767 pixels per side (browser limit). The max scale slider automatically adjusts based on your original image size to stay within this limit.
What does 'Keep aspect ratio' mean?
When enabled, changing the width automatically adjusts the height (and vice versa) to maintain the original image proportions, preventing distortion or stretching.
Can I upscale a small image to a larger size?
Yes, you can upscale up to 10× your original size (or the browser's 32,767px limit, whichever is lower). However, upscaling may result in some quality loss since the image data is being stretched.
What file format will the resized image be saved as?
The resized image is saved in your original upload format (JPG, PNG, WebP, etc.), preserving compatibility and quality.
