What you can do here
Drop in a PDF, pick a page, then place new content on top: text boxes (with font size and colour controls), rectangles (for highlighting, boxing fields, or covering content), and ovals. Each addition is queued — you can review and remove items before applying — and all your changes are written into a single new PDF.
Why “edit existing text” is rare
Most users searching for a PDF editor want to change words already on the page. The truth is that PDF text isn't editable the way a Word document is — characters are positioned individually with embedded fonts, kerning, and ligatures, so changing a word usually breaks the layout. Editors that claim to handle this either fail on real-world PDFs or flatten the page to an image first (which destroys text searchability for the whole document).
This tool focuses on what reliably works: adding new elements on top. For filling in form fields, use a dedicated form-fill tool. For redacting sensitive content, use a redaction tool that removes bytes from the file (covering with a white rectangle, as this tool can do, only hides visually — the underlying text is still in the PDF).

Edits happen with pdf-lib in your browser. The PDF is never uploaded.
