Can I upload a screenshot of my document?

It is usually refused. A full-page screenshot captures roughly 98 to 196 DPI depending on your screen, against the 300 DPI typically required, and it often includes interface furniture and a cropped page.

Can software improve a screenshot to 300 DPI?

No. Enlarging makes the pixels bigger, not more numerous. Detail that was never captured cannot be restored.

What about a screenshot on a 4K monitor?

Better, around 196 DPI on a page-filling view, but still short of 300 — and the interface furniture and cropping problems remain.

What should I do if the document only exists in a portal?

Look for a download link, or use print to PDF. That re-renders the page at full document size instead of recording your screen.

Why a screenshot of your document gets rejected

A screenshot records what your screen is showing, at the resolution your screen is showing it. That sounds obvious until you work out what it means for a full page of text: the file is not slightly under the requirement, it is a third of it.

The short answer. A full-page screenshot on a typical laptop captures the page at roughly 90 to 120 DPI, because that is all the screen was displaying. Filing systems commonly ask for 300. No processing can recover the difference — the detail was never captured.

The arithmetic

Suppose you open a Letter page in a viewer and it fills the height of a 1080-pixel-tall screen. The page is 11 inches tall, so you have captured 1080 ÷ 11 ≈ 98 pixels per inch. A 4K display roughly doubles that to about 196 — still short of 300, and only if the page really does fill the screen.

Screen	Page filling the height	Captured DPI
1080p laptop	1080 px over 11 in	≈ 98 DPI
1440p monitor	1440 px over 11 in	≈ 131 DPI
4K monitor	2160 px over 11 in	≈ 196 DPI
Phone screenshot	usually a partial page	lower still

Why it looks fine to you

Because you are looking at it on the same screen that produced it, at the same size. It is only when the file is opened at full size, or printed, that the missing detail shows — and the person who opens it that way is the reviewer.

The other three reasons a screenshot gets flagged

Interface furniture. Scroll bars, tabs, a browser address bar and a clock all end up in the file. It reads as a picture of a screen, not as a document.
It is visibly a partial view. A screenshot usually shows what fitted on the screen, so the bottom of the page is missing — and an incomplete document is refused on its own.
PNG size. Screenshots are usually PNG, which is lossless and large for a page of text, so the file can be both low-resolution and over the size limit at the same time.

What to send instead

If the document exists as a file, send that file. Do not photograph or screenshot a PDF you already have — export or download it.
If it only exists on paper, photograph it with the page filling the frame, then straighten it and even out the lighting.
If it only exists inside a web portal, look for a download or "print to PDF" option before resorting to a capture.

Print to PDF is the underused answer. It re-renders the page as a document at full page size, rather than recording what the screen happened to show.
