Frequently asked questions
- Why is the exact size important?
- When you upload the exact display size, the platform does not re-crop or re-compress your image aggressively, so it appears sharp and framed the way you intended.
- Are my images uploaded to a server?
- No. All compression happens locally in your browser. Your images never leave your device, which also makes the process instant — there is no upload or download wait.
- Will compressing reduce image quality?
- Compression removes data your eyes barely notice. At the default settings the difference is invisible in normal viewing. You can adjust the quality level under Options if you need finer control.
- What happens if my photo isn’t 851 × 315?
- The image is scaled until it fills the 851 × 315 frame, and any overflow is cropped evenly from the center. Proportions are never distorted — a mismatched aspect ratio simply loses a little from the edges.
- Can I use a photo straight from my phone?
- Yes. Phone photos are usually far larger than needed, which is ideal — downscaling to the exact size keeps them sharp. The tool also compresses the result so it uploads quickly.
About this tool
Every platform renders images at fixed display sizes, and the facebook cover photo slot is 851 × 315 pixels. Upload something else and the platform resizes and crops it for you — usually with aggressive re-compression and a crop you didn’t choose. Preparing the file at the exact size keeps that decision in your hands: what you see in the preview is what viewers get.
This tool uses cover-style resizing: your image is scaled until it completely fills the 851 × 315 frame, then cropped evenly from the center. Nothing is ever stretched or squashed, so proportions stay natural; if your photo’s aspect ratio differs from the target, the edges are trimmed symmetrically. For best results start from an image at least as large as the target — downscaling keeps things sharp, while a small source scaled up will look soft.
Like every tool on this site, resizing happens locally in your browser. The image is never uploaded, the result is ready instantly, and your original file is left untouched — download the resized copy and post it directly.
