JPG to PDF

Turn JPG and PNG pictures into PDF pages, one PDF each or all joined into one file in the order you set. JPEG photos and scans go into the PDF without being compressed again, and the PDF is written on your device. Nothing is uploaded.

Drop JPG or PNG files here Choose files JPG and PNG, up to 100 MB each. You can also paste a picture with Ctrl or Cmd V.

Options

Page size A4 US Letter Same as the picture

Leave a 12 mm margin

Bytes of your files sent anywhere: 0

Files are read and converted in this tab, in a background worker. The only requests the page makes are for its own scripts. Your files are never sent anywhere.

How it works

A PDF can hold a JPEG exactly as it is, so this page copies each JPEG's bytes into the PDF instead of decoding and compressing it again. The page looks as sharp as the photo, and the PDF is barely larger than the JPEG.

Phones store many photos sideways with a note saying which way is up. The page reads that note and turns the picture on the page, so portrait photos come out upright.

PNG pictures are drawn by the browser first and then stored losslessly, with any transparent areas kept.

The PDF is written by pdf-lib, an open-source library served from this site and loaded when you add your first picture. Join several into one file with Download as one PDF; use Move up and Move down on the rows to set the page order first.

How to convert JPG to PDF

Pick the page size. A4 or US Letter for something you will print or send as a form, or Same as the picture for a page that is just the picture.
Add the pictures. Drop the JPG or PNG files on the box, or click it to choose them.
Set the order. Use Move up and Move down on the rows if you want one PDF with the pages in a particular order.
Download. Download each PDF from its row, or use Download as one PDF to join them all.

Limits

Up to 100 MB a picture and 200 pictures at a time. PNG pictures are limited to 25 megapixels, because the PDF library holds their pixels in memory.
The text in a scanned page is not made searchable. That needs OCR, which this page does not do.
JPEGs in a rare encoding (CMYK without Adobe's marker, 12-bit or arithmetic-coded) are redrawn at quality 95 instead of copied, and the row says so.
Same as the picture uses the resolution stored in the file, so a 300 dpi scan of an A4 sheet gives an A4 page. Without one, it counts 96 pixels to the inch.
The PDF has no EXIF data: camera, date and location are not copied over.
Needs Chrome or Edge 69, Firefox 105 or Safari 16.4, or later.

Questions

Are my files uploaded?

No. The page reads each picture with your browser and converts it in a background worker in this tab. There is no server step. The meter under the drop zone counts the bytes the page and its worker send while they work, so you can check this yourself. The only things the page downloads are its own scripts and the PDF library.

Does it reduce the quality of my photos?

No, for JPEGs. Their bytes go into the PDF unchanged, so the picture in the PDF is the photo itself. PNGs are stored losslessly. The only pictures that change are rare JPEG encodings, which are redrawn at quality 95 with a note on the row.

How do I put several pictures in one PDF?

Add them all, wait for each row to finish, put them in order with Move up and Move down, then choose Download as one PDF. Each picture becomes one page.

Which page size should I choose?

A4 or US Letter when the PDF will be printed or uploaded to a form that expects a standard page. The picture is scaled to fit inside the margin, and the page turns landscape for a landscape picture. Same as the picture gives a page with no border, which suits photos and slides.

Why was my phone photo sideways in other converters?

Phones often save a photo in the sensor's orientation and add a tag that says how to turn it. Software that ignores the tag shows it sideways. This page reads the tag and turns the picture on the page.

Can I combine existing PDFs too?

This page turns pictures into PDFs. To join PDFs you already have, or split one, use PDF Tools.

Is it free?

Yes. There is no account, no watermark and no page limit beyond the sizes above.
