About this tool
Half the documents an office asks for start life as photographs. You point a phone at a mark sheet, a rent agreement or a set of receipts, and end up with six pictures where the upload box wants one PDF. This tool stacks those pictures into a single document, one image per page, in the order you set.
The page size choice matters more than it looks. A4 gives you a paper-shaped page with a margin, and the picture is fitted inside whole, so nothing is cut off and a photo that is wider than it is tall simply leaves white space above and below. Match the image proportions skips the paper metaphor entirely and makes the page the same shape as the picture, sized so that a screenshot lands at roughly the size it had on your screen. Use the first for anything that might be printed, the second for screenshots and photo collections.
Inside the PDF, every image is stored as a JPEG at high quality. That is what keeps a ten-photo document to a sensible size instead of tens of megabytes, and for camera photographs the re-encoding is not something you will see. Two consequences are worth knowing: a transparent background becomes white, and very fine text in a screenshot can soften a little. If a page needs to be crisp, feed in the largest version of the image you have.
Everything runs in your browser. The photos are decoded, re-encoded and assembled by your own device, and the finished PDF is handed back as a download. No upload, no account, and no copy of your documents left behind on a server. On an older handset a batch of big photos will take a few seconds per page, which is your phone doing the work rather than a queue somewhere.
How to use this tool
- Add your images. Choose JPG, PNG or WebP files, or drag them onto the box. You can add as many as you like within 50 MB per file and 100 MB in total.
- Set the order. One image becomes one page, in list order from top to bottom. Use the ↑ and ↓ arrows beside a filename to move it, and the × to remove one.
- Choose the page size. A4 puts each picture on a standard A4 page with a margin around it, fitted whole and never cropped. Match the image proportions makes each page exactly the shape of its picture instead.
- Run and download images.pdf. Every page is written in one go and the finished PDF downloads as images.pdf. Rename it afterwards if a form wants a particular filename.
What this tool does not do
- Only JPG, PNG and WebP. HEIC files from an iPhone are not accepted — save or convert them as JPG first.
- Every image is re-encoded as JPEG inside the PDF, so transparency becomes white and there is a small quality loss.
- One image per page. It cannot place two pictures on a single page.
- It does not read text out of your images. The PDF contains pictures, not searchable words.
- There is no per-image rotation, cropping or margin control here.
- A batch of large photos can be slow and memory-hungry on an older phone, because the encoding happens on your device.
Common questions
Are my photos changed in any way?
Each one is re-encoded as a high-quality JPEG inside the PDF. For ordinary photographs that is invisible. For a screenshot of small text, or a line drawing, you may notice slight softening around the sharp edges.
What happens to a transparent PNG?
The transparency is filled with white before the image goes into the page, because the PDF stores it as a JPEG. A logo with a see-through background will sit on a white rectangle.
Which page size should I pick?
A4 if the document is going to be printed or uploaded somewhere that expects paper-sized pages. Match the image proportions if you are making a PDF of screenshots or photos and do not want white space around them; that setting sizes the page so a screenshot comes out at roughly the size it appears on screen.
Does A4 crop my photo?
No. The picture is scaled to fit inside the margins with its proportions kept, so a wide photo leaves white space above and below rather than losing its edges.
Can I put two photos on the same page?
Not with this tool — it is strictly one image per page. For a printable sheet of repeated photos at a set physical size, use the Passport-photo layout tool.
Can I add a PDF to the set?
No, only images are accepted here. Convert your images to a PDF first, then use Merge PDF to join that with your existing document.
Will the text in my screenshots be searchable?
No. A screenshot is a picture of text, and it stays a picture inside the PDF. Nothing here reads or recognises the words.
It says my image is too large.
Images above 40 megapixels are refused, which is well beyond any phone camera but reachable with a stitched panorama or a high-resolution scan. Resize it first and try again.
