About Image Resizer
Oversized photos slow down websites and blow past email attachment limits. This resizer scales images to a maximum width while preserving aspect ratio, then downloads the optimized file instantly.
All processing is client-side. Pair with the File Compressor for additional byte savings or the Background Remover when you need alpha channels.
Frequently asked questions
Does FileShot store my images?
No. Resizing uses your browser canvas. Files are not uploaded.
What does max width mean?
We scale down so the wider edge does not exceed your pixel value. Smaller images are not upscaled.
Can I crop to exact dimensions?
This page focuses on max-width resize. Use File Converter for advanced crop presets.
