Edit · In your browser

An edit is a draft. Drafts stay close.

Falcon Edit is a PDF annotation tool that overlays text, translucent highlight rectangles, and opaque whiteout rectangles on existing pages. The original vector text and images remain unchanged; annotations are added on top. The work happens on your computer.

The PDF opens in this tab. Annotations — text, highlight, whiteout — are overlaid on your computer. The original vectors stay as they were. By design.

Why this tool exists

Edits are, by their nature, in-progress. A note on the corner of page three is not a settled thought. A highlight is a half-finished argument. A whiteout is a question you have not figured out the answer to yet. These are exactly the things you would not want a server to keep a record of.

When the editing happens on your computer, the in-progress thoughts stay where they belong. The PDF opens here. Text, highlight, and whiteout layers are added in this tab. The original vector text is unchanged underneath. When you save, the edit is yours. When you close the tab, the in-progress copies are gone.

FAQ

Common questions

Is my document uploaded when I edit it?

No. The PDF opens in this browser tab and your annotations are placed on your computer, then the new file is written here. The document never leaves your device to be marked up.

Can I change the existing text in the PDF?

Not directly. This tool lays annotations on top of the page — text boxes, highlights, and whiteout — while the original text and images underneath stay exactly as they were. It marks up a document rather than rewriting it.

Does whiteout actually delete what is under it?

No. A whiteout is an opaque rectangle drawn over the page; it hides the content visually but the words underneath remain in the file and can still be selected or recovered. To remove sensitive content for good, use the redact tool, which strips it out.

What can I add to a page?

Text in a position you choose, translucent highlight rectangles to draw attention, and opaque whiteout rectangles to cover something. All three are added on top and saved into the exported file.

Will my annotations stay put when the file is opened elsewhere?

Yes. They are written into the document at the positions you placed them, so they appear the same in any reader you send the file to.

How your file stays private

No upload

Opens, parses, rewrites on your device. Nothing about the contents transits a Falcon server.

Zero logs

No filenames, sizes, contents, or per-file telemetry. Operation counts only.

No trackers

Open the Network tab during use. Only first-party JS appears in the request log.

Metadata stripped

Authors, edit history, EXIF, and embedded thumbnails are removed alongside the visible content.
