Are my images uploaded to a server?

No. Everything runs inside your browser. Your images and the resulting PDF never touch a server.

Which image formats are supported?

JPG and PNG are embedded directly. WebP, GIF, BMP, and AVIF are automatically converted to PNG via an HTML canvas before embedding, so they work too.

How is each image sized on its PDF page?

Each page is set to the natural pixel dimensions of the image (converted from pixels at 72 dpi). The image fills the page exactly — no margins.

Can I reorder the images?

Yes. Use the Move Up / Move Down buttons in the list before clicking Convert.

Is there a limit on the number of images?

No enforced limit. Practical performance depends on your device's memory. Most devices handle dozens of images comfortably.
