Question 1

How do I annotate a PDF online?

Accepted Answer

Upload a PDF above. Once it is ready, continue into the document workspace, select text, and choose one of four highlight colors. You can attach a comment to the selected passage, jump back to saved highlights, zoom the page, or remove an annotation when it is no longer useful.

Question 2

What file types are supported?

Accepted Answer

This focused tool accepts PDF documents. Keeping the workflow PDF-specific lets KeepFlash preserve the page and text position needed for reliable text highlights and page navigation. For other file formats, use the import options available inside the main KeepFlash application.

Question 3

Will my PDF annotations be saved?

Accepted Answer

Yes. Highlights and comments are saved with the PDF note in your KeepFlash library, so you can close the tab and return later. The annotation list also gives you a practical way to review what you marked and jump from a note back to its original location in the document.

Question 4

Where is my PDF stored?

Accepted Answer

The initial browser upload is private and temporary. When you continue, KeepFlash attaches that file to your own library as a PDF note. The document is then served through authenticated, time-limited access rather than a public file URL, helping keep your source material inside your account.

Question 5

Can I search my PDF notes and annotations?

Accepted Answer

Your PDF becomes part of your KeepFlash library, and your attached notes remain available as connected knowledge rather than a separate scratchpad. This makes it easier to rediscover an idea, combine it with related material, and use the right source as context when working across your saved knowledge.

Question 6

Is the online PDF annotator private?

Accepted Answer

Guest uploads use an isolated temporary storage area and an opaque, one-time handoff token. The file is validated as a PDF and expires automatically if you do not continue. After it is claimed, normal KeepFlash ownership checks protect access to both the PDF and its annotations.
