โ FAQ
Q. Does enlarging reduce quality?
A. Yes, bitmap images lose quality when enlarged. Shrinking is recommended when possible.
Q. What file formats are supported?
A. Major formats including JPG, PNG, GIF, and WebP are supported.
Q. What is the difference between resizing and cropping?
A. Resizing scales the entire image to new dimensions, while cropping cuts away parts of the image to focus on a specific area. This tool resizes the full image, optionally preserving its original proportions.
Q. Does resizing reduce file size?
A. Yes, shrinking an image reduces the number of pixels, which lowers the file size. For further compression without changing dimensions, use a dedicated image compressor.
Q. What are the recommended image sizes for Instagram?
A. Instagram feed posts work best at 1080x1080 (square) or 1080x1350 (portrait). Stories and Reels use 1080x1920. Turn off aspect ratio lock to enter exact dimensions.
Q. Can I resize animated GIFs?
A. Static GIFs can be resized normally. Animated GIFs may only process the first frame depending on the format. Verify the output to ensure the animation is preserved.
