About Image resizer

The Image Resizer lets you scale images to exact pixel dimensions or by a percentage of the original size, with a lock-aspect-ratio option to prevent distortion. It processes entirely client-side using the Canvas API — no files are uploaded. Common uses include resizing photos for social media profiles (Twitter header: 1500×500, Instagram square: 1080×1080), scaling product images for e-commerce platforms, and shrinking email attachments that need to meet a dimension or file size limit.
