Turn on Word's formatting marks before removing whitespace that seems to control alignment or paragraph spacing. Work in a saved copy, identify the character at the problem location, then change one thing and inspect both the document structure and a fresh PDF.
Reveal the characters before deciding what to remove
Use the Show/Hide paragraph-symbol button to expose whitespace that ordinary reading conceals. A large gap may contain a tab, several spaces, or an empty paragraph; those inputs call for different decisions.
Microsoft's Show/Hide documentation covers desktop Word for Microsoft 365 and Word 2024, as well as older editions and named Mac versions. For Windows, persistent display choices are under File > Options > Display. On Mac, use Word > Preferences > View. This article leads with Microsoft 365 or Word 2024 desktop; it does not establish the same settings path for Word for the web or mobile.
The official pages were checked on October 6, 2026, alongside the ToolboxHub component source. Word itself was not run for this article. The document below is an illustrative fixture you can reproduce, not a report of a completed Office test.
Read the marks as evidence, not as a cleanup instruction
Use the visible marks to locate the cause, then decide whether the underlying character is intentional. Microsoft's Display options reference identifies tabs as arrows, spaces as dots, and paragraph endings as paragraph symbols. A paragraph mark separates paragraphs; deleting it can join text that should stay separate.
Suppose a policy page has a label aligned with a reference number, a mailing address split across two lines, and a blank line above a heading. You may want the label alignment and address line break to remain, while removing one accidental empty paragraph. A global deletion of tabs or paragraph marks would treat all three as errors and damage the page.
If no whitespace character explains a gap, stop deleting. The cause may be paragraph spacing, an indent, or layout around an object. Inspect the affected paragraph's settings in your desktop edition instead of adding and removing spaces until the page happens to look right. A visible mark helps diagnose the input; it does not certify the intended layout.
Build a small fixture with an explicit expected result
Create a new, disposable Windows desktop document with default paragraph formatting. Microsoft's Word keyboard reference confirms Shift+Enter for a line break on Windows; the Mac branch uses Shift+Return. The following inputs model three different sources of whitespace on a policy page:
- Type
Policy ID:, press Tab once, typeOPS-17, then press Enter. - Type
Delivery address:, press Shift+Enter, typeWarehouse A, then press Enter. - Press Enter once more to create an empty paragraph, then type
Scopeand press Enter.
Turn on Show/Hide. The expected structure is a tab between the label and ID, a manual line break between the address label and Warehouse A, and an empty paragraph immediately before Scope. Do not expect a fixed physical gap: tab stops, font metrics and paragraph styles affect the appearance. This is a structural verification exercise with specified inputs, not a promise that every Word template renders identically.
In the disposable fixture, select only the empty paragraph immediately above Scope and delete it. The expected result is that Scope moves directly after the address paragraph without that extra empty paragraph between them. The tab still separates Policy ID from OPS-17, and Warehouse A stays on its separate line within the address paragraph. If either retained feature changes, undo and repeat with a narrower selection.
For a production document, first make a working copy with a distinct name. Use the same inspection approach, but do not assume the fixture's deletion is appropriate for your policy page. Its blank paragraph may be intentional, and a neighboring paragraph or object may depend on that location. Keep changes small enough that you can explain and reverse each one.
Check the saved document and the exported page separately
Reopen the saved working DOCX and inspect the affected passage with marks visible. Confirm that the ID text, address wording and paragraph boundaries remain correct; then view the page with marks hidden to assess readability.
Export a new PDF with a different filename. Microsoft's desktop PDF instructions use File > Save a Copy for a saved Word file, with PDF selected as the format. The page names Microsoft 365 and older Word editions but currently does not list Word 2024 in its Word applicability line. If Word 2024 or a Mac build presents different labels, use its documented PDF export option and inspect the actual output; do not assume the Windows route matches every interface.
Open that PDF and compare the label alignment, address line arrangement, heading position and page count. Displaying formatting marks is an editing aid. It is not proof that export options, hidden text, fonts or pagination are correct.
For an additional visual pass, use ToolboxHub PDF to Image to render the affected page. Select the new PDF, confirm its filename and page count, choose PNG and 150 DPI, and set a custom page range such as 1 for a one-page fixture. Convert and download the page image. The expected output for a file named policy-review.pdf is policy-review_page001.png, a raster representation of that PDF page.
Reopen the downloaded image rather than judging only the thumbnail. The code offers PNG/JPG output, DPI choices and page selection; it cannot open DOCX, reveal Word's hidden marks, change paragraph settings or repair the source document. The image is useful for visual comparison but loses document structure and selectable text. A one-page image also cannot verify other pages or accessibility.
Diagnose symptoms before repeating the export
If marks stay visible after you turn Show/Hide off, check the persistent display selections. Individually selected marks can remain enabled; clear the relevant choice if you want it hidden. That symptom does not mean the characters were inserted by the button.
If the heading jumps into the preceding text, you probably removed a paragraph boundary rather than only the empty paragraph. Undo, show the marks again and inspect the selection. If the gap remains despite there being no extra characters, inspect paragraph spacing or layout instead of deleting more text.
If the downloaded image shows the previous layout, confirm that you exported a fresh PDF from the saved working copy and selected that exact filename. Increasing DPI cannot repair an outdated export. A page-range error means the selection must fit the PDF's actual page count; begin with one valid page, then expand the range if needed.
Older feature documentation is not a support recommendation. Office 2016 and 2019 support ended in October 2025, and Office 2021 reaches retirement on October 13, 2026. Use an edition supported by your organization and consult its matching help when menus differ.
Frequently asked questions
Does turning Show/Hide off delete the characters?
No. It changes their display. The tab, spaces and paragraph endings remain in the document until you edit them.
Why do some marks remain visible after I hide them?
Persistent display choices can keep selected marks on. Check Windows Display options or the corresponding Mac View preferences.
Should I replace every tab with spaces?
Only if the document's layout rule requires it and you verify the result. A tab can intentionally align a label; blanket replacement can alter spacing throughout the file.
Can PDF to Image prove the Word structure is correct?
No. It renders visible PDF pages. Verify paragraphs and hidden characters in Word, then use the PDF and downloaded image for the separate visual check.
