OutputOne PDF with one page per image, each page the size of its image

One image per page

Every image gets its own page, and the page takes the size of the image so nothing is cropped or stretched. JPG images are embedded without re-compression, so a 3 MB photo adds about 3 MB to the PDF. PNG, and also WebP, are supported too.

Typical uses

Combine receipts for an expense report, turn phone photos of a signed contract into one attachment, or build a document from screenshots. Put the pages in order with the up and down arrows; the PDF is rebuilt after every change.

Photo orientation

The page shows the image the way it is stored in the file. A phone photo that carries an "rotate on display" tag instead of rotated pixels can appear sideways; if so, rotate the final PDF with the Rotate PDF tool.

How to use

FAQ

Can I convert several JPGs into one PDF?

Yes. Drop them together or add more later, then order them with the arrows. You get one PDF with one image per page.

Does it reduce the image quality?

No. JPG and PNG files are embedded as they are, without re-compression.

Which page size does it use?

Each page matches its image size, measured in pixels as PDF points. Printers will scale it to the paper.

Which formats are accepted?

JPG and PNG directly; WebP, GIF and BMP are redrawn as PNG first.

Are my images uploaded?

No. The PDF is created by pdf-lib in your browser.
