Can I edit the text that's already in the PDF?
Yes. Choose Edit existing text and every line the page contains is outlined; click one and retype it. The original wording is genuinely deleted from the file rather than covered over with a white box, so it won't come back through copy-paste or a search — which is the part most tools get wrong. Two honest caveats: the replacement is drawn in one of the fonts built into the PDF format, so it matches exactly for the Helvetica, Arial, Times and Courier families that most documents use but only approximately for a custom embedded font; and each line is edited where it sits, so a much longer replacement won't re-wrap the paragraph around it.
Is editing a PDF here really private?
Yes. The file is opened and re-saved inside your browser tab — it's never uploaded, and there's no server involved at any point. You can confirm it by watching your browser's network panel while you work.
Does the Cover tool actually remove what's underneath?
No — and this matters. Cover draws an opaque box over the content, which hides it visually but leaves the original text in the file where it can still be copied out or found by search. It's fine for tidying up a draft; it is not redaction, so don't use it to hide confidential information.
Why can't I select text on my scanned document?
Because there isn't any. A scan is a photograph of a page, so what looks like writing is just pixels — there are no letters in the file to click on. Editing scanned text needs OCR to recognise the words first, which is a separate tool we haven't shipped yet.
What happens to emoji or non-Latin text I type?
The editor uses the fonts built into the PDF format itself, which cover Latin characters but not emoji, Chinese, Arabic, Cyrillic and similar. Anything outside that set becomes a question mark, and you'll get a warning before the file is written rather than a surprise afterwards. Embedding a full Unicode font would add megabytes to every file you download.
Can I add pages from another PDF?
Not inside the editor. Combine the documents with Merge PDF first, then open the merged file here — same result, and it keeps this tool focused on one file at a time.
Do I need an account?
No. There is no sign-up, no email, and no usage cap. Nothing about your files is logged.
