Social Media Image Resizer

Resize a photo to fit Instagram, Facebook, X, LinkedIn or YouTube — free, instant, entirely on your device.

Why exact dimensions matter on social

Every platform crops or compresses images that don't match its expected dimensions, which is how a carefully composed photo ends up with the wrong crop or visible compression artifacts after posting. Resizing to the platform's exact target size before uploading avoids that guesswork — the image fills the frame the way it was designed to.

Each preset here center-crops your image to fill the target dimensions exactly, so nothing gets stretched or squashed.

Why one size doesn't fit every platform

Every social network crops, scales or pads images to its own preferred dimensions the moment you upload them, which is why a photo that looks perfectly framed on your phone can end up cropped awkwardly, or squeezed with visible letterboxing, once it's posted. Feeds, stories, covers and profile photos each use different aspect ratios on the same platform, so there's rarely a single size that works everywhere.

This tool resizes your image to the exact dimensions a given placement expects before you upload it, so what you see in the preview is what your audience sees — no unexpected crop, no auto-added padding. For platform-specific presets, the dedicated Facebook, Instagram, LinkedIn, Pinterest, TikTok, X and YouTube resizers below handle each network's current recommended sizes individually.

Checking your result before you post

After resizing, it's worth zooming into the preview and checking the edges specifically — that's where an unwanted crop or an oddly placed subject is easiest to spot before it becomes a mistake you notice only after publishing. Text overlays deserve particular attention, since they're the first thing to become unreadable if a resize pushes them too close to an edge.

All resizing happens locally in your browser using the Canvas API, so you can experiment with different presets freely before downloading — nothing is uploaded until you actually save the result to your device.
