Frequently Asked Questions
Can I resize an image without losing quality?
Upscaling (making larger) will reduce quality as new pixels are interpolated. Downscaling maintains quality well. Use 90%+ quality setting for best results.
What is aspect ratio and should I maintain it?
Aspect ratio is the width-to-height proportion. Maintaining it prevents stretching or squishing. Disable it only when targeting exact dimensions.
Can I resize to a specific pixel size?
Yes, enter the exact width and height in the fields. Enable 'Maintain aspect ratio' if you only want to constrain one dimension.
Can I batch resize multiple images?
Yes, drop multiple images at once and they will all be resized to your specified dimensions.
What formats can I resize?
JPG, PNG, WebP, and GIF. The output format matches the input format by default.
