What happens
4What happens, and why
Drop one or more photos and they become one PDF, a page each, in the order you picked them. The PDF is rebuilt whenever the list changes. The one choice is the page size: each image’s own, or an A4 or Letter sheet turned to match it.
A JPEG is not decoded on its way in. PDF readers carry their own JPEG decoder, so the compressed picture can be copied into the PDF exactly as it sits in your file — the same bytes, with no second round of compression. That is why the badge says it was not re-encoded, and why a PDF of ten phone photos is about the size of the ten photos. Choosing A4 does not change that: the page says how large to draw the picture, and the pixels stay as they were.
What stays behind is what is not the picture. A phone photo carries camera data — the model, the time, often the place it was taken — and a PDF sent to a school or a landlord has no reason to carry it, so it is left out. The orientation written there is read first and applied by the page, so a portrait photo stands up. Some phones also tuck a second, hidden image after the photo, for HDR or depth; that is left out too. A colour profile, such as the Display P3 an iPhone writes, is kept, in the place a PDF reader looks for it.
Other formats go in the most faithful way PDF allows. A PNG without transparency is copied as stored as well; PNG with transparency, GIF, BMP and TIFF are unpacked and stored without loss; HEIC, AVIF and lossy WebP are saved again as JPEG at quality 92, because their pixels are already an approximation and storing them without loss would make each page many times larger for nothing you could see. Each file’s row says which happened, and the badge is the weakest of them. Nothing is uploaded: the images are read in this tab and the PDF is written here.
FAQ
5Does it lower the quality
Not for a JPEG. The picture is copied into the PDF as stored, so it is the same compressed data it was, byte for byte. Only HEIC, AVIF and lossy WebP images are compressed again, as JPEG at quality 92, and the row for each one says so.
Will a phone photo come out sideways
No. Phones store many photos sideways and write down which way is up. This page reads that note and turns the picture with the page, without touching its bytes. The note itself is left out with the rest of the camera data, since the page now does its job.
Which page size should I pick
Image size makes every page exactly its picture, with nothing added — good for reading on a screen. A4 or Letter puts each picture on a sheet of paper, turned to match, which is what a form or a printer expects. Neither resamples the picture: the page decides how big it looks, and the pixels stay as they were.
Is the location removed from my photos
Yes. EXIF, XMP and IPTC blocks and comments — where a camera keeps its model, the time and a GPS position — are left out of every JPEG before it goes into the PDF. Images in other formats are either copied without their metadata or decoded to pixels, so none comes along from them either.
Are the images uploaded
No. The browser reads them from your disk and writes the PDF on this page. There is no upload endpoint on this site, so there is nowhere for a photo to go, and nothing about the images is logged.
