Worked example
A 4000 × 3000 photo resized to 1200 × 900 is much smaller and still looks sharp on a screen.
Frequently asked questions
Will resizing keep the aspect ratio?
Only if you change width and height in the same proportion. This version uses the exact numbers you enter.
What size should I use for a form?
Follow the form's stated limit. 1200 pixels wide is a common safe choice for screen use.
Are my images uploaded?
No. Resizing happens in your browser.
What format is the download?
PNG, to avoid extra quality loss during resizing.
Can I enlarge a small image?
Yes, but enlarging cannot add detail — a small blurry image stays blurry.
