Frequently asked questions
Will my image be stretched?
The image is scaled to fill 300×300. If your original is not square it may be stretched slightly; start from a square crop to avoid distortion.
Can I resize a PNG with transparency?
Yes. PNG transparency is kept, so logos and avatars with see-through areas resize cleanly.

Resizing usually reduces file size as a side effect, but if you need a specific KB limit, use a compression tool afterward.
