Proportional resize without a cloud upload

Resizer recalculates the paired dimension when aspect-ratio lock is on — not a server that receives your file first. Edit width or height in pixels, toggle the lock, and download or copy the output from a client-side canvas. It does not include smart crop, content-aware scaling, or automatic focal-point framing.

Why use a maintain aspect ratio image resizer in the browser?

Cloud resizers upload your file before proportions are preserved. Pix-8 locks locally — the practical path when you need a maintain aspect ratio image resizer that recalculates dimensions on-device without a server round-trip.

Aspect-ratio lock toggle

Enable lock, edit width or height, and the paired dimension updates automatically to preserve original proportions.

Client-side processing

Your image is read locally and resized on a canvas in the browser. Proportions are calculated before export — nothing is uploaded.

Flexible export

Download or copy the resized file — single image or batch — with optional EXIF stripping before export.

Frequently asked questions

Can I resize an image while maintaining aspect ratio without uploading?
