Why Image Sizes Matter for Social Media
Every social media platform crops, compresses, and displays images according to its own dimension requirements. Uploading the wrong size means your photo gets auto-cropped, appears blurry due to upscaling, or loses important details.
When you resize image for Instagram before uploading, you stay in full control. A 1080×1080px square is the gold standard for feed posts. Portraits perform best at 1080×1350px. Stories and Reels require 1080×1920px.

Is my image uploaded to a server?
No. All image processing happens locally in your browser using the HTML5 Canvas API. Your photos never leave your device. No file is uploaded, stored, or transmitted to any server.
What is the difference between Crop, Fit, and Stretch modes?
Crop fills the target canvas by centre-cropping any excess. Fit keeps your entire image visible with optional blurred background. Stretch ignores aspect ratio and fills the exact target dimensions.
