Frequently asked questions

Enter your desired width and height in pixels, or use the 50% and 75% quick preset buttons. With "Maintain aspect ratio" checked, changing one dimension automatically adjusts the other to prevent stretching. The Original button restores the full uploaded dimensions.

Yes. When "Maintain aspect ratio" is checked, our tool automatically calculates the proportional height when you change the width (and vice versa). This ensures your image never looks squished or stretched — it stays perfectly proportioned.

Downsizing (making images smaller) preserves visual sharpness. Upscaling (making images larger than the original) may reduce clarity since new pixels must be interpolated. For best results, always start with the highest resolution source available and resize downward.

Our resize tool supports JPG, PNG, WebP, GIF, BMP, and TIFF images. The tool preserves your original format — a PNG stays PNG after resizing. If you need to change formats, switch to the Convert tab.
