Frequently Asked Questions
No. Resizing happens on a canvas in your browser, so your image never leaves your device.
Leave 'Keep the aspect ratio' ticked, which is the default: change either dimension and the other is recalculated so the image is not stretched. Turn it off to set width and height independently, for example to force a 16:9 canvas.
Almost always, because fewer pixels means less to encode. The exact new size is shown under the preview before you download.
Some browsers use high-quality downsampling, which keeps small text crisp, but any image scaled down far loses detail. Scaling 4000 px down to 400 px keeps the outline of text, not its edges. Use the quality setting to trade detail for size.
