Frequently asked questions
Can I control the page order?
Yes β after adding files, use the β β buttons to arrange them. The PDF follows your list top to bottom.
A4 or fit-to-image β which should I choose?
A4 with margins looks like a normal document and prints predictably β best for forms and submissions. Fit-to-image makes each page exactly the image's shape β best for photos.
Are my photos uploaded?
No. The PDF is assembled in your browser's memory and downloaded straight from there.
How many images can I combine?
There is no fixed limit. The work happens in your browser, so the practical ceiling is your device's memory. A few hundred photos is fine on a normal laptop; very large batches of high-resolution images are slower.
Can I mix JPG, PNG and screenshots in one PDF?
Yes. Add them all and arrange the order you want. Each image becomes a page regardless of its original format.
Combining several images into a single document
Most people arriving here are not converting one picture. They have photographed or scanned a multi-page document with a phone, and now a portal, an employer or a bank wants it back as one PDF rather than eight separate JPGs. That is exactly what this tool is for. Add every image, put them in the right order, and you get a single file that opens the same way on any device.
The order is the part worth spending ten seconds on. Phone galleries sort by the time a photo was taken, which is usually correct for a document you scanned top to bottom, but not if you went back and re-shot a blurry page. After adding your files, use the arrow buttons to move pages until the list reads the way the document should read, then build the PDF.
Choosing A4 or fit to image
A4 places each image on a standard page with margins, which is what you want for anything that will be printed, filed or reviewed as a document. Pages come out a uniform size even when your photos were not, and the result looks like a scanned document rather than a photo album. Fit to image makes each page exactly the shape of the picture on it, which suits photographs, screenshots and artwork where white borders would look wrong. If you are submitting to a form and the instructions do not say, choose A4.
Getting a clean result from phone photos
A PDF built from photographs is only as good as the photographs. Shoot in even light rather than directly under a lamp, which creates a bright patch that washes out text. Hold the phone parallel to the page instead of at an angle, so the edges stay square. Fill the frame with the document and leave only a small border. If your phone offers a document or scan mode, use it, because it flattens the perspective and lifts the contrast before you ever reach this page.
If the finished PDF is too large to upload
Combining ten phone photos can easily produce a file of several megabytes, which many portals will reject. Build the PDF here first, then run it through the PDF compressor and set the limit the form asks for, such as 1MB or 500KB. Compressing once at the end gives a better result than shrinking each image beforehand, because the compressor can see the whole document and spend the available space where it is needed.
Working the other way round
If you already have a PDF and need the images out of it, the PDF to JPG converter does the reverse and saves each page as a separate picture. To join PDFs you already have rather than images, use merge PDF instead.
Your files stay on your device
Scanned documents are often the most sensitive files people handle: identity documents, bank statements, signed agreements, medical paperwork. This tool builds the PDF inside your browser using your own device's processing, so none of those images are transmitted to a server, stored, or seen by anyone. There is no account, no queue and no retention period, because there is nothing on the other end to retain them.
