Aspect Ratio Converter

Crop and resize images to any platform aspect ratio. Preview and download instantly.

Every placement has its own aspect ratio: 9:16 for TikTok, Reels, and YouTube Shorts; 4:5 portrait for Instagram Feed; 1:1 square for Facebook and LinkedIn feed; 16:9 landscape for YouTube in-stream and display. Shipping the wrong ratio means the platform either rejects the creative or auto-crops it, which silently slices the logo, the CTA, or the key subject out of frame. This tool crops correctly once and gives you back a clean export per ratio.

Creative teams use this between the master-file hand-off and final ad trafficking. Instead of opening Photoshop for every platform variant, you drop the master, pick the ratio, preview the crop to confirm the subject stays inside the aspect-ratio safe zone, and download. The tool center-crops by default and shows the result full-size before export so you can catch any edge case before the asset goes live.

Everything runs in the browser using the Canvas API. Safe for unreleased campaigns, agency review cycles, and NDA-restricted brand assets, your image never leaves your device.

Why It Matters

Running the same creative across platforms usually means re-cropping for each one. TikTok wants 9:16, YouTube needs 16:9, Instagram feed works best at 4:5. This tool handles the math for you. Drop an image, pick the target ratio, and get a center-cropped result at the highest resolution your original supports. The crop happens entirely in your browser, no upload, no waiting. Use it alongside the Ad Spec Checker to make sure the output also meets platform size and format requirements.
