Crop (fill) or pad (fit) your image to each platform's recommended dimensions—Instagram square and story, YouTube thumbnail, Facebook cover, and more. Without memorizing any specs, one button gives you an image at exactly the right size.
How to use
- Upload an image and pick the platform-spec button you want.
- Choose 'Fill (crop)' or 'Fit (pad)' mode.
- Adjust what gets cropped with the position slider and pick a format (JPG, PNG, WebP).
- Press 'Save' to download the correctly sized image.
FAQ
- How do 'Fill' and 'Fit' differ?
- 'Fill' crops the image so it fully covers the target size, while 'Fit' places the entire image and fills the leftover area with the background color. When a logo or person must not be cut off, 'Fit' is the safe choice.
- Are the given specs accurate?
- It uses each platform's common recommended sizes—Instagram square 1080×1080, story 1080×1920, YouTube thumbnail 1280×720, and so on. Platform policies can change, so treat them as a reference.
- Is the image I upload sent to a server?
- No. Resizing and cropping are all handled in your browser, and the image is never sent to or stored on a server.
