How do I convert a JPG to PDF?
Why anything asks for a PDF
Rarely because the format is special. Almost always because a PDF is one file
that arrives in a fixed order and opens identically on every machine. A folder of
IMG_4471.jpg through IMG_4478.jpg is eight attachments in an
arbitrary sequence that somebody at the other end has to sort out.
So the useful part of this conversion is the ordering, which is why it is the first thing the tool asks you about. Phones hand files over in whatever sequence the picker felt like, and the arrow buttons beside each image put them right.
Page size, in practice
Choose A4 or US Letter when the document might be printed or read by someone in an office. Each photograph is scaled to fit inside the margins and keeps its own proportions; wide photos turn the page landscape automatically.
Choose match each image when the PDF will only ever be viewed on a screen. Each page becomes exactly the shape of its photograph with no white space around it, which suits a portfolio or a set of screenshots and looks wrong in a form submission.
Getting the size down before the limit refuses it
Upload forms that want a PDF very often cap it at 5 or 10 MB, and phone photographs blow through that with three pages. Two things help, in this order.
Crop first. A photographed document usually contains a great deal of desk, and every one of those pixels costs bytes in the finished PDF while carrying no information. The cropper takes seconds and often halves the result on its own.
Then drop the quality. Balanced is very hard to distinguish from Best on screen. Small is genuinely lower quality and is the right choice when the alternative is a document that will not send.
A note about photographs of text
A photographed page is a picture of text, not text. It cannot be searched, selected, copied or read by a screen reader, and it takes far more space than the words would. If the document exists as a file — a Word document, a web page, a form you filled in — exporting that to PDF directly produces something better in every respect.
Photographing is the answer when the original is genuinely on paper. In that case, good even light and a straight-on angle do more for legibility than any setting on this page.
If the finished document is too large for the form that wants it, the fix is upstream rather than in the PDF: compress the photographs or crop away the desk around them before they become pages. Scanned documents need the opposite treatment from photographs.
Common questions
- Can I put several JPGs into one PDF?
- Yes — up to thirty, and the order is yours to set. Each image becomes one page. This is the common case: photographing several pages of a form or several receipts and needing them to arrive as a single document rather than as an inbox full of attachments.
- Are my photos uploaded?
- No. Most sites offering this upload your files to a server, convert them there and promise to delete them later, which asks you to trust both the promise and the company — with documents that are frequently identification, bank statements or medical forms. Here the PDF is assembled by your own browser and there is no server that could receive anything.
- Why is my PDF so big?
- Because a PDF is a container around the images, not a compression format. Ten four-megabyte photos make a forty-megabyte document. Drop the page quality to Balanced or Small before creating it — that re-encodes each photo at a lower setting on the way in, and Small typically produces a document around a third of the size.
- The text in my photographed document is hard to read. What can I do?
- Use the Best quality setting, and crop the photograph to the page before you convert — every pixel spent on the desk around the document is a pixel not spent on the text. If the document exists as a file anywhere, exporting it to PDF directly will always beat photographing it, because the text stays text instead of becoming a picture of text.
