When you copy something in Windows, the app you copied from usually puts the same content on the clipboard in several formats at once, such as rich text, HTML and plain text, and the app you paste into takes the most descriptive format it recognizes. That is why the same copy keeps its fonts in one app, arrives as plain text in another, and pastes as a file path in a third. IntelliClip from Automata Labs keeps a searchable, offline history of what you copy, so you can get back the text, links, images and file paths you need after the clipboard has moved on.

What is a clipboard format?
A clipboard format is a label that tells Windows and apps what kind of data is on the clipboard and how it is laid out. Microsoft’s Clipboard Formats documentation describes several kinds: standard formats defined by the system, registered formats that applications agree on by name, and private formats used inside one app.
Some common ones, from Microsoft’s list of standard clipboard formats and its HTML Clipboard Format page:
| Format | Kind | What it holds |
|---|---|---|
| CF_UNICODETEXT | Standard | Unicode text |
| CF_TEXT | Standard | Text in an older ANSI encoding |
| CF_DIB | Standard | A bitmap image |
| CF_HDROP | Standard | ”A list of files,” as when you copy files in File Explorer |
| HTML Format | Registered | An HTML fragment, always UTF-8 |
| Rich Text Format | Registered | Styled text, as used by word processors |
Why does one copy put several formats on the clipboard?
Because the app you copy from cannot know where you will paste. Microsoft explains that a window can place the same information on the clipboard in more than one format, starting with the most descriptive. Its example: when you copy styled text from a word processor, the document “might first place data on the clipboard in a registered format, such as RTF,” and then add less descriptive formats such as plain text.
That way a word processor on the other end gets the full styling, and a plain text editor still gets something it can use.
How does the app I paste into choose a format?
According to Microsoft, “a window pasting information from the clipboard typically retrieves a clipboard object in the first format it recognizes,” and because formats are listed in the order they were placed, “the first recognized format is also the most descriptive.”
Microsoft continues the word processor example: if the pasting window recognizes RTF, the RTF data is pasted. “Otherwise, the text data is pasted into the document and the formatting information is lost.”
So a paste that loses formatting is usually not a fault. The receiving app simply did not recognize the richer format, or chose to ignore it.
Why does pasting from a web page bring its fonts and colors with it?
Browsers typically put an HTML version of your selection on the clipboard along with plain text. Microsoft’s HTML format documentation describes this format, registered as “HTML Format,” as a header followed by HTML, with offsets named StartHTML, EndHTML, StartFragment and EndFragment that mark where the HTML and the selected fragment begin and end.
An app that understands HTML, such as a word processor or email editor, picks that format and rebuilds the styling, so the web page’s fonts, colors and links come along. A plain text editor picks the text format and shows none of it. If you usually want the plain version, see our guide to pasting without formatting by default.
Why do accents or symbols sometimes turn into question marks?
This is often an encoding mismatch. Windows offers both a Unicode text format and an older ANSI one. Microsoft documents that the system synthesizes conversions between certain formats: if an app asks for a format that is not on the clipboard, “the system converts an available format to the requested format,” and CF_TEXT, CF_OEMTEXT and CF_UNICODETEXT can be converted into one another.
An older app that only asks for ANSI text gets a converted copy, and characters that do not exist in its code page can be lost. Modern apps use Unicode, so this happens less often today, but it still shows up with legacy software.
Why does copying a file paste a path in one app and the file in another?
When you copy files in File Explorer, the clipboard holds a file list, the CF_HDROP format that Microsoft describes as identifying “a list of files.” Explorer and many apps understand that and paste the files themselves. Apps that do not understand file lists may fall back to a text form if one is offered, or paste nothing.
| What you copied | Formats typically offered | What you see when pasting |
|---|---|---|
| Styled text from a word processor | Rich text, HTML, plain text | Styled in rich editors, plain in text editors |
| A selection from a web page | HTML, plain text | Web styling in rich editors |
| Files in File Explorer | File list | Files in Explorer, sometimes nothing elsewhere |
| A screenshot | Bitmap | An image where images are accepted |
How does Windows decide what goes into clipboard history?
Microsoft defines special registered formats that let the app doing the copying control this. Placing data in ExcludeClipboardContent keeps the item out of clipboard history and cloud sync. CanIncludeInClipboardHistory and CanUploadToCloudClipboard let an app opt an item in or out of history and of syncing to other devices separately. Password managers can use these so copied secrets do not linger. For more on keeping sensitive items out, see clipboard history privacy.
How does IntelliClip help when the clipboard is overwritten?
The Windows clipboard holds one current item, and every new copy replaces it. Windows clipboard history helps, but it has limits, which we cover in the Windows clipboard history 25 item limit.
IntelliClip is a clipboard manager for Windows. According to its Microsoft Store listing, it:
- Saves your clipboard history and makes it searchable, powered by “a local SQLite FTS5 engine.”
- Stores “images, plain text, flattened rich-text, and file paths,” and keeps them after restarts.
- Is keyboard first: “Press Alt+V, type to search, use arrow keys to select, and hit Enter to paste.”
- Ranks suggestions based on your active window.
- Is password aware, designed to avoid saving sensitive password-manager content.
- Works offline, with no cloud sync and no telemetry.
Press Alt+V, type a few letters and paste something you copied days ago.

One honest note based on that listing: IntelliClip describes rich text as “flattened,” so think of it as a way to recover the content you copied, rather than a byte-for-byte replay of every clipboard format the original app offered. For heavy formatting, copying again from the source is still the most faithful option. If you work mostly in Microsoft 365 apps, our comparison of the Office Clipboard and Windows clipboard history explains how those two differ.
Frequently asked questions
Why does the same copy paste differently in two apps?
Each app picks the most descriptive format it recognizes from the several that were placed on the clipboard.
Is HTML on the clipboard stored as UTF-8 or UTF-16?
Microsoft’s documentation says the HTML clipboard format always uses UTF-8, an exception to the Windows API’s usual UTF-16.
Can I see which formats are on the clipboard right now?
Not in Windows Settings. Developer tools that enumerate clipboard formats can list them.
Why is my copied image not in some apps’ paste?
The app may not accept bitmap formats, or the source may have offered the image only in a format that app does not recognize.
Does IntelliClip sync my clipboard to the cloud?
No. Its listing says it is 100% offline with no cloud sync and no telemetry.
