❓ Frequently Asked Questions
Reducing size maintains quality well. Enlarging may cause some blur as pixels are interpolated. For best results when enlarging, keep it under 200% of original size.
When locked, changing width automatically adjusts height (and vice versa) to maintain the original proportions. Unlock it to stretch or squish your image freely.
You can upload JPG, PNG, WebP, GIF, and BMP images. The resized image will be downloaded as PNG for best quality.
We recommend images up to 50MB. Very large images may be slow depending on your device's capabilities since everything is processed locally.
