Frequently Asked Questions

How do I resize an image without losing quality?

Scaling down keeps images sharp. For the best result, keep the aspect ratio locked and export as PNG, or as JPG or WebP at 85% quality or higher.

Can I make an image larger?

Yes, but enlarging cannot add detail that was not in the original, so upscaled images look softer.

What size should a profile picture or passport photo be?

Requirements vary by site and country. Enter the exact pixel width and height the form asks for, then check the file size shown before downloading.
