Frequently asked questions
How do I resize a photo to 300×300 pixels?
Drop the image above. It's resized to exactly 300×300 px instantly. "Crop to fill" trims the edges so nothing is stretched; "Fit with padding" keeps the whole image and adds a background color.
Will the image be stretched?
No — unless you choose "Stretch". The default crops from the center so proportions stay natural.
What aspect ratio is 300×300?
300×300 is a 1:1 aspect ratio (square).
Can I also limit the file size?
Yes. Enter a value in "Max size KB" and the resized image is compressed to fit under that limit.
Are my photos uploaded?
No. Resizing happens in your browser. Nothing is sent to a server, so it is safe for personal photos and documents.
