Frequently asked questions
What resize modes are there?
Fixed pixels (stretch to an exact size), percentage scale, and fit-a-box that preserves aspect ratio — either contained inside the box or cropped to cover it.
Can I resize for a specific platform?
Yes. Platform presets cover common Instagram, Open Graph, and marketplace sizes; enabling one overrides the manual size.
How does the watermark work?
Add a watermark image, set its opacity and size relative to the picture width, and place it on a 3×3 grid of positions. It’s composited in your browser.
What format are the results?
PNG, which is lossless and keeps transparency. Every image is processed locally and nothing is uploaded.
