Image to PDF: getting photos into the format forms want
The problem it solves
A receipt photo, a screenshot of a confirmation, a scanned signature or an ID copy often has to go into an expense claim or application that only takes PDFs. Wrapping the picture in a PDF fixes that in seconds.
Quality and size
The image is embedded as it is, so the PDF is about as large as the picture. A 6 MB phone photo gives a PDF of roughly 6 MB, so resize or compress it first if an upload limit applies.
Photographing documents well
Place the page on a flat, plain surface in daylight, shoot straight from above and keep the edges in frame. A clear photo gives a readable PDF, and if you later run OCR it also gives better text.
Several pages
This tool makes one PDF per image. To combine pages, merge the PDFs afterwards, or select all the images on your phone or computer and use Print, then Save as PDF.
iPhone photos
Photos in HEIC format have to be changed to JPG before they can be used here. The simplest route is to change the camera setting to Most Compatible.
Check the finished PDF at full size before you upload it to a portal. A sideways or cropped page is much easier to fix now than after rejection.
