About the Facebook Post Tool
Facebook displays shared images at 1200x630px in the news feed. Images that don't match this ratio are automatically cropped by the platform — often cutting off important parts of your photo. DCPIXEL pre-resizes your image to the exact dimensions for a perfect, uncropped Facebook post.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.
Free — No Account, No Limits
DCPIXEL is completely free with no daily limits, no watermarks, and no registration. We never process your files on our servers, so we can offer this permanently at no cost.
