Make a small square that still reads clearly
A 300×300 canvas suits a small avatar, catalogue thumbnail or compact icon. The default Fit mode preserves the source proportions and includes the whole image, adding padding where necessary. Choose Fill for a full-bleed square, or Stretch only when distortion is intentional.
Get a better result
Small text can become unreadable at 300 pixels. Crop around a clear subject and check the downloaded file at its actual size. Circular avatar displays hide the square corners, so keep the important part away from the edges.
A quick workflow
- Choose a clear original; the output starts at 300 by 300 pixels.
- Use Fit for complete content or Fill and focus controls for a tighter square.
- Process and check the thumbnail at native size before downloading.
When this tool helps
Prepare compact profile images and thumbnail grids. If a site requires a larger original, use its stated dimensions rather than assuming every avatar service accepts 300×300.
