About the Social Media Image Resizer

The ByteTools Social Media Image Resizer crops and scales any photo to the exact pixel dimensions each platform wants: Instagram posts and Stories, Facebook covers, X (Twitter) headers, LinkedIn banners, YouTube thumbnails, Pinterest pins and more. Pick a preset and the image is cover-fitted — scaled to fill the frame completely, then cropped.

Because automatic center-cropping often beheads the subject, you can drag the photo inside the frame to choose exactly which part survives the crop. What you see in the preview is pixel-for-pixel what you download.

Sizes reflect current platform specifications, which do change — each preset shows its dimensions so you can verify against the platform's help pages. All processing is 100% local in your browser; your photos are never uploaded.

Frequently asked questions

What size should an Instagram post be?

1080 × 1080 for squares, 1080 × 1350 for portrait (which occupies the most feed space), and 1080 × 566 for landscape. Stories and Reels are 1080 × 1920. Upload at exactly these sizes and Instagram applies minimal recompression.

What are the correct sizes for Facebook and X banners?

A Facebook Page cover displays around 820 × 312 on desktop, and an X (Twitter) header is 1500 × 500. Both platforms crop differently across devices, so keep faces and text near the center of the banner where every device shows them.

What is the best YouTube thumbnail size?

1280 × 720 pixels (16:9), under 2 MB. That is YouTube's recommended spec — smaller images look blurry on TVs and high-DPI screens where thumbnails render large.

Why does the tool crop my image instead of squashing it?

Squashing distorts faces and objects because the aspect ratios differ. Cover-fitting scales the photo until it fills the frame and trims the overflow — the standard, professional approach — and the drag control lets you decide what gets trimmed.

Are these dimensions up to date?

The presets match the platforms' published specifications as of 2026, and each preset displays its exact pixels so you can double-check. Platform sizes do evolve — if a spec changes, the safe rule is to keep the same aspect ratio at equal or higher resolution.
