Images to PDF. One tidy file, no upload.

How to use the Images to PDF tool

This tool combines JPG and PNG images into one PDF, one image per page, in the order you set. It writes the PDF file itself in your browser, placing each image on a page of the size and margin you choose. It is for anyone turning photos, scans or screenshots into a single document to send, upload or print.

Step by step

1. 1
   Add your images

   Drop JPG or PNG files on the card that says Drop images here, or click it to choose files. You can pick several at once. Other file types are skipped. The options and a tile for each image appear once they load.

2. 2
   Set the page order

   Each tile shows its page number. Drag tiles to reorder them, or use the up and down arrow buttons on a tile. The cross button removes that image. Use + Add more to add images to the end, or Clear to start over.

3. 3
   Choose the page size

   Under Page size, Fit to image makes every page the size of its image, plus any margin. A4 and Letter use standard paper sizes and scale each image to fit, centered on the page.

4. 4
   Set orientation and margin

   Orientation applies to A4 and Letter only. Auto turns a page landscape when the image is wider than it is tall; Portrait and Landscape force one direction for every page. Margin adds None, Small (24 points, a third of an inch) or Medium (48 points, two thirds of an inch) of white space around each image.

5. 5
   Build and download

   Press Build PDF & download. The button reads Building while it works, then the browser saves the file as images.pdf and a short message confirms how many images went in.

Reading the result

• With Fit to image, one image pixel becomes one point, which is 1/72 of an inch. A 3000 pixel wide photo makes a page about 42 inches wide. It looks normal on screen, but choose A4 or Letter if you plan to print.
• With A4 or Letter, each image is scaled up or down so it fills the space inside the margin without cropping, and any leftover space stays white.
• JPG images go into the PDF as they are, with no quality loss. PNG images are drawn onto a white background and saved as high quality JPG inside the PDF, so any transparent areas turn white.

Tips and common mistakes

• Small images on A4 or Letter are enlarged to fill the page and can look soft. Use Fit to image for screenshots and small graphics.
• Every image is written as a standard RGB color image. A grayscale or CMYK JPG may not display correctly in the PDF, so re-save it as a normal color JPG or as a PNG first.
• Phone photos often store their rotation as a tag instead of in the pixels. JPGs are copied into the PDF untouched and the PDF does not read that tag, so such a photo can come out sideways or stretched. If that happens, rotate and re-save it in a photo editor, or save it as a PNG first.
• Large camera photos make a large PDF because JPGs are not recompressed. Resize them before adding them if the file has to stay under an email or upload limit.
• Check the page numbers on the tiles before you build. The PDF follows that order exactly.

Privacy and limits

Your images are read and the PDF is assembled in your browser. Nothing is uploaded and nothing is saved; reloading the page clears the list. Only JPG and PNG are accepted, and very large batches can be slow or run out of memory on a phone because every image is held in memory while the PDF is built.

Back to the tool

Everything an images-to-PDF tool should do.

• Combine JPG & PNG images into a single downloadable PDF, any number at once.
• Reorder by dragging tiles, or nudge images with the up and down arrow buttons.
• Choose the page size, fit each page exactly to its image, or standardise on A4 or US Letter.
• Set the orientation to portrait, landscape, or auto-detect per image from its shape.
• Add a margin, none, small or medium, with every image centred on the page.
• Remove individual images before building, and add more at any time without starting over.
