About Images to PDF

Need to turn a set of images into a PDF document? Upload JPG or PNG files, drag to reorder, choose a page size (A4, Letter, or fit-to-image), and download a single PDF. Images are centered on each page with automatic scaling. Everything runs in your browser using pdf-lib — no files leave your device.

Frequently Asked Questions

What image formats are supported?

JPG/JPEG and PNG images are supported. Other formats should be converted to JPG or PNG first using our image converter tools.

Is my file uploaded to a server?

No. Transmute processes everything locally in your browser using JavaScript and the Canvas API. Your files never leave your device — there is no server, no upload, no cloud processing.

Can I choose the page size?

Yes. Choose between A4, US Letter, or 'Fit to Image' which makes each page exactly the size of the image.

Are images stretched to fill the page?

No. Images are scaled proportionally to fit within the page margins while maintaining their aspect ratio.
