Turn pictures into a PDF, one page each
Choose the photographs or screenshots, drag them into the order somebody should read them in, and this writes a single document with one page for each. You decide what the page is: exactly the shape of the picture, which is what it does unless you say otherwise, or A4 or US Letter if the thing is going to be printed. The pictures go in as the files they already are.
Put pictures into one PDF
Bring the pictures, put them in the order you want to read them, and this writes one document with a page for each. The pictures go in exactly as they are, with nothing re-compressed, and the whole thing is assembled by this tab so none of them is uploaded.
The page is exactly the picture, so there is no room for a margin and nothing is trimmed or padded. This is the default because a screenshot dropped onto A4 comes out as a stamp in the middle of a sheet.
Your pictures go into the document as the files they already are, so a photograph is the same JPEG inside the PDF that it was on disk and nothing is decoded, resized or re-compressed along the way. That is also why the two formats are PNG and JPEG and not more: those are the two a PDF can carry untouched. Anything a picture carries in its own metadata goes in with it. One picture stops at 25 MB.
Images to PDF, step by step
- Bring the pictures inChoose them or drop them on the box, in any number of goes. Each one is read as it arrives, and the panel tells you how big the picture is and what size page it is about to become before anything is written.
- Choose the pageFit the page to the picture and nothing is padded or trimmed, which is the sensible answer for screenshots and receipts. Pick a paper size instead and the sheet turns to match each picture, so a landscape photograph gets a landscape page.
- Write the documentOne press gives you one PDF with the pages in the order shown. Drag a row to move it, or take one out with the cross beside it, and press again as many times as you like until the order reads properly.
Your pictures go into the document as the files they already are
A PDF can hold a JPEG or a PNG in its own compression, stored as an object the page refers to and draws into a rectangle, which means the bytes that came off the camera are the bytes sitting inside the finished document. Nothing here decodes a picture, paints it onto a canvas or writes it out again, so there is no second round of JPEG compression softening every edge and no colour shift from a conversion nobody asked for. That is also the reason the two formats accepted are those two and no others: they are the ones the format can carry untouched, and a HEIC or a WebP would have to be decoded and re-encoded on the way in, which is exactly the quiet quality loss this avoids. Even the page sizes are worked out from the numbers in each picture's own header, so the document is assembled without a single decoded image ever being held in memory.
The everyday version of this job is a receipt, an expenses claim, or a set of photographs of a document that somebody has asked to be sent as one file. The awkward part is never the conversion. It is that the pictures are of your bank card, your passport, the inside of your flat or your child’s school form, and the free sites that will do it want you to upload every one of them first.
Putting a JPEG into a PDF is a small and completely specified operation: the picture becomes an object in the file, the page refers to it, and a rectangle says where it goes. There is no processing worth having a server for. So this does it in the tab, which means the pictures stay on your machine and the document appears in your downloads folder without anything having been sent anywhere.
The page size is the part worth a moment. Fitting the page to the picture makes a document that looks right on a screen, which is where most of these end up. Choosing a paper size makes one that prints predictably, and even then the sheet is turned to match the picture rather than the picture being shrunk to fit the sheet. Nothing is ever cropped to fill a page, because trimming somebody’s document is not a decision a web page gets to make.
Questions
Why is the page not A4 by default?
Because dropping a wide screenshot onto a portrait sheet leaves it as a small stamp in the middle of a lot of white, and that is what nearly every site in this category does without asking. Fitting the page to the picture is the honest default. A4 and US Letter are one click away for when the thing is genuinely going to a printer.
Will the photographs come out smaller or softer than they went in?
No, and they cannot be, because the file is embedded as it stands rather than being decoded and encoded again, so a photograph inside the document is byte for byte the one on your disk. That does mean a document made from twenty phone photographs is roughly the size of twenty phone photographs.
Can it take a HEIC from my iPhone?
Not directly, because a PDF has no way to store one and it would have to be converted first, which is a decision about quality that ought to be yours rather than a page's. Export as JPEG from Photos, or change the camera setting to Most Compatible, and everything after that works normally.
What order do the pages come out in?
The order shown in the list, which starts as the order you chose the files in and is yours to drag around after that. Nothing is sorted by filename behind your back, because scanned pages are routinely named in an order nobody wants to read them in.
