Aspect Ratio Scaler & Patcher

How Proportional Scaling Works

Aspect ratio scaling preserves the mathematical relationship between an image's width and height. If you force an image into a new size without respecting this ratio, the media will become stretched, squashed, or distorted. Our utility operates entirely client-side using proportional arithmetic to guarantee zero latency. No images are uploaded to a server, ensuring your data remains private.

About Aspect Ratios & Padding

Sometimes, you need to fit an image into a strict frame (like a 16:9 YouTube video or a 9:16 TikTok) without cropping out any important details. To do this, you must expand the underlying canvas, creating "bars" around the media.

• Pillarboxing: Occurs when your original image is narrower than the target format. The canvas expands horizontally, adding vertical bars to the left and right sides of the image.
• Letterboxing: Occurs when your original image is wider than the target format. The canvas expands vertically, adding horizontal bars to the top and bottom of the image.

Common standard display ratios include:
