Photos of paper, arriving as one file
The job is nearly always the same. Somebody needs a signed document, a set of receipts, a delivery note, a certificate or a page of a drawing, and what you have is four photos on your phone taken at slightly different angles. Sending four images is untidy and half the time the recipient cannot open them in order. One PDF is what was wanted.
Put the images in, drag them into the right order, and press the button. The order on screen is the page order.
Phone photos come out the right way up
A phone stores its photos in landscape with a rotation flag in the file, and software that ignores the flag shows the picture on its side. A surprising number of image-to-PDF converters ignore it, which is why you end up with a PDF full of sideways documents.
The flag is applied here before anything else happens, so what you see in the list is what lands on the page.
How this tool works
Each image is decoded in the page, placed on a sheet at the size you choose, and embedded. JPEGs go in as JPEGs and PNGs as PNGs, so nothing is re-encoded and no quality is lost on the way in.
The picture is scaled to fit the page while keeping its shape, so nothing is stretched or cropped. Anything wider than it is tall can be given a landscape sheet automatically, which stops a photograph arriving as a small strip in the middle of a portrait page.
The size setting is the one that matters
This is where most converters quietly let you down. A modern phone photo is around 12 megapixels. Drop a dozen of them into a PDF untouched and you get a 40MB file, which most mail servers will refuse outright and most portals will reject.
So people make the PDF, fail to send it, and go looking for a PDF compressor five minutes later. Two tools for one job, because the first one did not think about the second.
Shrinking the longest side to 2000 pixels is more than enough for anything read on a screen, and it is enough for a clean A4 print at roughly 170 dots per inch. It is the difference between a 3MB PDF and a 40MB one carrying the same information. Set it to zero if you genuinely need full resolution, for a drawing that will be zoomed into or anything going to print at large format.
Page size, and the one setting nobody offers
A4 is right for the UK, Europe, Australia and most of the world.Letter is right for the US and Canada. Getting this wrong is not fatal but it shows: the document prints with odd margins or scaled down slightly.
Match each image is the option worth knowing about. Instead of fitting a photograph onto a fixed page and leaving white bars down the sides, it makes each page the shape of its own image. Nothing is cropped and nothing is letterboxed. For a set of photos rather than a set of documents it is almost always the better answer, and most converters do not offer it at all.
With a fixed page size, match each image orientation turns the page landscape for a landscape photo, so a wide picture is not squeezed into a portrait page at half the size.
No limits, and nothing uploaded
Everything happens on this page, in your browser. Your images are never sent anywhere, which matters more here than almost anywhere else on this site: the things people turn into PDFs are contracts, passports, payslips, medical letters, bank statements and signed forms.
The large PDF sites all upload. Read their privacy pages and you will find file retention measured in hours. That may be perfectly fine for a holiday photo. It is a strange thing to accept for a scan of your passport.
There is no cap on how many images, no maximum file size, no daily quota, no watermark and no account. Nothing is metered because there is no server doing the work to meter.
What this does not do
It does not run text recognition, so the result is a picture of a document rather than a document you can search or copy text out of. If you need searchable text you need OCR, which is a different job.
It also does not straighten, deskew or clean up a photograph. If the picture was taken at an angle, the PDF will contain a picture taken at an angle. Your phone's own scanner mode does that part better than any web page can, so use it before you come here.
Site photographs are evidence before they are a PDF
The images stay on your machine and are discarded when you close the tab. Nothing is uploaded and nothing is logged.
Photographs carry more than they look like they do. A site photo has a timestamp and often GPS coordinates in its metadata, a receipt has a card number on it, and a photographed document is still that document. People convert exactly those three things, and an upload sends the metadata along with the picture without ever mentioning it.
Common questions
Why do my phone photos come out sideways in other converters?
Because a phone stores photos in landscape with a rotation flag in the file, and a lot of image to PDF converters ignore that flag. This tool applies it before anything else happens, so the photo in the list is the photo that lands on the page, the right way up.
Why is my PDF too big to email?
A modern phone photo is around 12 megapixels, so a dozen of them dropped in untouched come out around 40MB, which most mail servers refuse and most portals reject. Shrinking the longest side to 2000 pixels is enough for a screen and for a clean A4 print at roughly 170 dots per inch, and that is the difference between a 3MB file and a 40MB one carrying the same information. Set it to zero for full resolution.
Should I choose A4 or Letter for the page size?
A4 is right for the UK, Europe, Australia and most of the world. Letter is right for the US and Canada. Getting it wrong is not fatal, but the document prints with odd margins or scaled down slightly.
What does "match each image" do?
Instead of fitting a photograph onto a fixed page and leaving white bars down the sides, it makes each page the shape of its own image, so nothing is cropped and nothing is letterboxed. For a set of photos rather than a set of documents it is almost always the better choice.
Is there a limit on how many images I can add?
No. There is no cap on how many images, no maximum file size, no daily quota, no watermark and no account, because there is no server doing the work to meter.
Can I search or copy the text out of the finished PDF?
No. This tool does not run text recognition, so the result is a picture of a document rather than a document you can search or copy text from. Recognising text in a scan is a different job.
Are my photos uploaded anywhere?
No. Everything happens in your browser, so the images stay on your machine and are discarded when you close the tab. That removes the limits along with the risk: no cap on how many photos, no maximum size, no watermark and no queue. It matters because the pictures people bundle into a PDF are usually site progress shots, damage records or scans of identity documents, and none of those wants a copy sitting on a stranger’s server.
