Frequently Asked Questions
Will resizing an image reduce its quality?
Enlarging an image beyond its original dimensions can make it appear blurry because pixels are being stretched. Shrinking an image generally preserves quality well. Always try to scale down, not up, for best results.
What is aspect ratio lock?
Aspect ratio lock keeps the ratio of width to height constant. If you type a new width, the height adjusts automatically so the image does not look squashed or stretched.
Can I resize a PNG without losing its transparency?
Yes. If you choose PNG as the output format, transparency (alpha channel) is preserved after resizing.
What is the maximum image size supported?
The resized image can be up to 10,000 pixels on each side. Very large images also depend on your device memory.
Can I resize to a specific file size in KB?
The tool resizes by pixel dimensions, not target file size. To reduce file size in KB, use the Image Compressor tool after resizing.
