The Sizes That Actually Matter in 2026

Most platforms accept a wide range and then compress whatever you give them. Exporting at the native size avoids that compression pass and is the single easiest quality win.

Instagram feed: 1080 × 1080 (square) or 1080 × 1350 (4:5 portrait — takes more screen, generally better). Stories and Reels: 1080 × 1920 (9:16). Facebook feed: 1200 × 630 for links, 1080 × 1350 for photos. LinkedIn: 1200 × 627 posts, 1584 × 396 banner. X/Twitter: 1600 × 900. YouTube thumbnail: 1280 × 720. Pinterest: 1000 × 1500 (2:3). TikTok cover: 1080 × 1920.

One Image, Every Platform, Without Redesigning It

The practical workflow: design once at the tallest ratio you need (usually 9:16), keep your subject and any text inside the middle 60% of the frame, then resize down to the other formats. Because the important content lives in the safe centre, a centre crop to 1:1 or 4:5 will not cut anything you need.

Designing square-first is the common mistake — every crop to a taller format then has to invent space that does not exist. If you are producing Stories or Reels, also check that nothing critical sits in the top or bottom ~15%, where the platform UI overlays your image.

Frequently Asked Questions

What platforms and sizes are supported?

We support 14 sizes across 7 platforms: Instagram (post, story/reel, profile), Facebook (post, cover, story), LinkedIn (post, banner), Twitter/X (post, header), TikTok (cover), YouTube (thumbnail, banner), and Pinterest (pin).

How does the cropping work?

Images are center-cropped to fit each platform's dimensions. The tool preserves the central subject of your image while filling the entire target area.

Can I download all sizes at once?

Yes. Select the sizes you need, generate them all, then click "Download All" to save every version. Each file is named with the platform and dimensions.

Can I resize for Instagram without cropping?

Not without changing the aspect ratio — that is geometry, not a tool limitation. If your source is a different shape than the target, something has to give: crop the edges, or add padding (letterbox bars) to preserve the whole frame. This tool center-crops, which suits most photos; when the full frame matters, add your own padding in a design tool first so the image arrives already at the target ratio.

How do I convert an image to 9:16?

Pick the Story/Reel size (1080 × 1920) — that is 9:16. A landscape source will lose a lot of its sides at that ratio, so start from the tallest version of the image you have.

Does resizing reduce my image quality?

Downsizing a large image is effectively lossless to the eye. Upscaling a small one is not — it will look soft, because the detail was never captured. Always start from the largest original you have; export at the platform's exact pixel size rather than letting the app compress an oversized file.

Are my images uploaded to a server?

No. Resizing happens in your browser using the canvas API — the file never leaves your device, which also means it works on private or client images without a confidentiality concern.
