FAQ
Frequently asked questions
How big will a 50 KB image be in pixels?
Commonly around 500–800 px wide for a photo, more for simple graphics. The exact size depends on how much detail the image has.
Why not just lower the quality?
Heavy compression creates blocky artefacts around faces and text. Reducing dimensions gives a cleaner look at the same file size.
My image is already below 50 KB — will it change?
If it's a JPG under 50 KB, it's returned unchanged.
Which format do I get?
JPG by default, which forms accept everywhere. You can choose WebP instead for websites.
