Resize an image to 300×300
This page resizes your photo to exactly 300×300 pixels — the right size and dimensions for a small square thumbnail. Everything runs in your browser — your image is processed on your own device — and the on-screen preview is the same file you download, so the size is exact, never an estimate.
Resize an image to 300×300
- Open your image — drag it onto the tool, choose a file, or paste from your clipboard.
- It's preset to 300×300 — the width and height are already filled in for you.
- Check the preview — the before → after readout shows the exact new size and file weight.
- Download — save the resized image, ready to upload.
Tip: start big, then resize down
Resizing a large image down to 300×300 keeps it sharp. Enlarging a small image past its original size can't add detail, so begin with the highest-resolution copy you have.
