Are these the official platform sizes?

Yes. Every preset matches the platform's current recommended dimensions. We update them when platforms change their specs.

Will resizing crop my image?

Pick 'Fill (crop)' to crop to the exact ratio, or 'Fit (pad)' to keep the full image with white padding.

One-click resize to the exact pixel size every major platform recommends. All processing happens in your browser.

Use our Image Resizer to enter any width and height in pixels.
