JPG to PDF 2 MB

2 MB is 2,048 KB, or 2,097,152 bytes. For photos turned into a PDF it is generous up to about ten pages and starts to bite past twenty. This page says where that line sits, so you can decide between one file and several before you build anything.

The page count where 2 MB stops being generous

Ten photos share 2 MB at about 200 KB each, which is a good, sharp page. Twenty share it at 100 KB each, which is still readable. Forty get 50 KB each, and at that point the photographs look like photographs of photographs.

Twenty pages is the practical line. Past it, splitting the set into two files gives you a better result than any target ever will, because each file gets the whole budget again. Convert the set once, look at what each page costs, then decide whether one file or two is the answer.

Build then compress

The images to PDF tool assembles the photos into pages with the original pixels intact. The 2 MB compress target then works the document down and reads the result back before it hands it over.

The compress step reports the quality it chose. On a generous target like this one, expect a high setting and very little visible change from the assembled file. On the published bench the quality chosen when a page render won had a median of 92 out of 100.

When to use a different number

For a mail attachment against a 2 MB gateway limit, aim lower. Mail encoding adds about a third, so a 2 MB PDF arrives as roughly 2.7 MB. A 1 MB target clears that comfortably.

For an upload form that genuinely allows 2 MB, use it. Nothing is gained by leaving budget on the table when the pages carry small print or handwriting that a tighter target would soften.

Questions people ask

Is 2 MB enough for twenty photos in one PDF?
Yes, at about 100 KB per page, which stays readable. Forty photos drops it to 50 KB each and the quality shows. Splitting into two files is a better answer than pushing the target down.
What quality does a 2 MB target use on photos?
A high one, usually. The engine picks a quality by sampling and walks down only as far as it must. On the published bench the median chosen quality when a page render won was 92 out of 100.
Can I email a 2 MB PDF of photos?
Against a 5 MB or 10 MB limit, yes. Against a 2 MB limit, no, because mail encoding inflates it to roughly 2.7 MB in transit. Compress to about 1.5 MB for that case.
Does page size affect how big the PDF gets?
Yes. A larger page needs more pixels to look sharp, so it costs more bytes at the same quality. The images to PDF step lets you set the page size, and that choice feeds directly into what the compress step has to do.
