Which image formats are supported?

JPG, PNG, and WebP. We re-encode each image as JPEG inside the PDF for size; PNGs with transparency are flattened on a white background.

How are images sized on the page?

"Fit" scales the image to fill the page while preserving aspect ratio (with white margins where needed). "Cover" crops the image to exactly match the page. "Original" places the image at its native size, centred.

No. The conversion runs entirely in your browser using pdf-lib.
