How it works
Each image becomes a page. In “Image size” mode the page matches the JPG dimensions, with no recompression. In A4 mode the image is centred with a margin and scaled proportionally. Reorder images by drag and drop before creating the PDF.
FAQ
Is photo quality reduced?
No: the JPG is inserted as-is into the PDF, without re-encoding.
Can I mix JPG and PNG?
Yes. Both formats are accepted on this page and on “PNG to PDF” alike, and the type is detected from the file signature, not its extension.
How do I get a light PDF from phone photos?
Downsize the photos first (2000 px wide is enough), or compress the resulting PDF with the Compress tool.
