Documents and print
- On-screen documents / slides: 1920 × 1080 is plenty.
- Print needs pixels at 300 PPI: an A4 page (8.27 × 11.69 in) needs about 2480 × 3508 px; a 4 × 6 in photo needs 1200 × 1800 px.
How to resize without stretching
- Upload your image to the resizer.
- Keep Lock aspect ratio on and set the width. The height follows.
- If the target has a different ratio, such as a landscape photo going to a 1:1 Instagram post, crop first in a photo editor so the subject isn’t distorted.
- Choose WebP or JPG at 75–85% for photos.
