What the editor can and cannot do

Add text anywhere on a page and choose its font, size, weight and colour. Highlight passages in several colours, draw freehand with an adjustable pen, and drop sticky-note comments that PDF readers list and open. Your original text and images are not re-rendered, so the document stays sharp and searchable.

To sign, draw your signature with a mouse or finger, type it, or use a photo of it. It is placed as a picture you can move and resize, and you can reuse it on other pages. This is a visual signature, not a certificate-based digital signature.

Edit text works by replacement: click a line of existing text, and it is covered with the page background while your new wording is written on top. When the document carries its own font, the replacement is drawn in that same font, weight and style, so it blends in. Characters that the document's font does not contain (PDFs usually include only the letters they use) switch that line to the closest standard font instead, and the editor tells you when that happens. The old wording is hidden, not deleted from the file, so use Redact for anything that must be removed for good.

Added text uses the standard PDF fonts (sans-serif, serif and monospace). Text in other scripts, and emoji, are placed as an image so they still appear correctly, but cannot be selected afterwards.

Frequently asked questions

Can I change the text that is already in my PDF?

Yes, by replacement. Choose Edit text and click the line you want to change. The original is covered and your new text is drawn in its place, in the same font where the document provides it, at the same size and colour. It works best for short corrections. Scanned pages have no text to click; use Add text over them instead.

Is the signature legally valid?

It is an image of your signature placed on the page, which many everyday forms accept. It is not a cryptographic digital signature with a certificate. Check what the recipient requires.

Will other people see my comments?

Yes. Comments are saved as standard PDF sticky notes, which readers such as Adobe Acrobat, Preview and browser PDF viewers show as a note icon that opens on click.

Can I undo changes?

Yes. Undo and Redo cover every action, and nothing is written to a file until you choose Save PDF. Your original file is never modified.

Does editing reduce the quality of my PDF?

No. Existing pages are kept as they are. Your additions are drawn on top as vector graphics and text.

Will replaced text keep the same font?

Usually, yes. The editor reuses the font embedded in your PDF, including bold and italic. PDFs normally contain only the characters the document used, so if you type a character that is missing from that font, the line switches to the closest standard font and a note tells you. Text replaced in the original font is placed as a high-resolution image, so it looks right but cannot be selected.
