    Drop your image file onto the upload area, or tap the area to choose it from your device.

  2. Run it

    Press Download, Don →. The button stays disabled until there is something to work on, and each file shows its own progress and result.

What this tool does

Every platform's real dimensions

Instagram, YouTube, Facebook, X and LinkedIn are preset with square, portrait, story and landscape sizes, so you never have to look the numbers up.

Zoom and position before you export

Zoom in and drag the photo inside the frame, so the crop keeps the part of the picture that matters instead of the centre by default.

Runs fully in your browser with no upload and no sign-up

The image is cropped and saved as PNG or JPEG by your browser, so nothing is uploaded and there is no sign-up.
