Frequently Asked Questions
Making an image smaller (downscaling) with this tool preserves visual quality well. Making an image larger (upscaling) will soften or pixelate it because you are adding pixels that did not exist in the original. For best results, always start from the largest version of your image.
No — this tool resizes by pixel dimensions, not by file size. To reduce file size in KB, use the Image Compressor tool which lets you adjust quality to hit a target file size.
Yes. You can upload a WebP image and resize it, or choose WebP as the output format for your resized image. WebP typically produces smaller file sizes than JPG or PNG at similar quality.
Yes. Common social media dimensions: Instagram square (1080×1080), Instagram portrait (1080×1350), Twitter header (1500×500), Facebook cover (820×312). Enter these dimensions in the width and height fields.
The tool processes images in your browser using a canvas element. Very large images (over 20MB or above 8000×8000 pixels) may be slow to process on lower-end devices, but there is no hard limit imposed by the tool.
