Resize Image to 300×300 Pixels: what it does
A 300 × 300 pixel image is a small square asset suitable for certain website thumbnails, avatars and application uploads. The dimensions define the pixel count, not the file size in KB. A JPG and PNG with exactly these dimensions can have substantially different file sizes.
Use a true square output for 300-by-300 requirements
A 300 × 300 image contains 90,000 pixels. A rectangular photo must either lose its edges when cropped, fit into the new square with padding, or be distorted by stretching. The crop and fit choices determine which trade-off you make.
At such a small square size, icons and portraits need simple compositions. If a portal also specifies a maximum KB size, check the output file size separately, because 300 × 300 pixels does not guarantee a particular number of KB.
A compact square avatar or logo
The Resize panel opens with 300 × 300 pixels. Crop to fill for a clean square icon, or choose Fit to keep a rectangular logo intact with background margins.
Before you download: limits and trade-offs
Tiny graphics should be examined at 100% display size after export. Hairlines and small lettering may become hard to read when reduced to only 300 pixels across.
