Frequently Asked Questions
Does resizing reduce file size?
Yes, resizing to smaller dimensions reduces file size because there are fewer pixels to store. For further size reduction without changing dimensions, use the Image Compressor tool.
Will resizing stretch my image?
Not with "Constrain Proportions" enabled — it maintains the original aspect ratio automatically. Disable it to set width and height independently.
What is the maximum image size I can resize?
Up to 20 MB. Very large images may take a moment to process depending on your device.
Can I resize to a specific aspect ratio?
Enter the desired width; the tool calculates the correct height automatically when proportions are locked. For a specific ratio, disable proportions and enter both values manually.
