Frequently Asked Questions
Can I maintain the aspect ratio when resizing?
Yes. Use the Fit mode and set only the width or height — the other dimension adjusts automatically to prevent distortion.
What is the difference between Fit, Fill, and Exact modes?
Fit scales the image to fit within your target dimensions while preserving the aspect ratio. Fill crops the image to exactly fill the target size. Exact stretches the image to match the exact dimensions you set, which may distort the image.
Does resizing reduce image quality?
Downscaling preserves quality well. Upscaling beyond the original resolution may introduce some softness, as no new detail can be created.
What is the maximum image size?
You can upload images up to 20 MB. There is no limit on the output dimensions, though very large sizes may take longer to process.
Does the tool detect my image's original dimensions?
Yes. When you upload an image, the original width and height are detected and displayed automatically so you can see the starting size before resizing.
