    What this tool does, exactly

    Add text, a picture, a highlight or your signature anywhere on the page. By default the edits are drawn into the page itself rather than left as annotations a reader can ignore or strip — and the finished file is re-opened and checked before you are offered anything.

    What you can add
    Text, a picture from your device, a highlight over what is already there, and a signature you draw with a finger or a mouse. Each one can be moved and resized before you save, and removed entirely.
    Your edits are drawn into the page
    Most editors leave what you add as an annotation, which is a separate object a reader is free to ignore, hide or strip. This tool draws them into the page's own content by default, so the edit is the document. Keep them editable instead if you would rather come back and change them later.
    What it does not do
    Rewrite the text that is already in the document. A PDF stores placed glyphs rather than a document, so a paragraph cannot be reflowed and a line set in an embedded font cannot be typed into with that same font. This tool adds to the page and says so, rather than offering an edit that would look wrong.
    Letters the format cannot carry
    PDF's built-in fonts cannot encode Cyrillic, Chinese, Japanese, Korean or emoji. Rather than refuse those characters, the tool draws them with your own browser's font and places them as a picture. It looks right and prints right; it is not selectable text, and the tool tells you when that happened.
    Covering something is not hiding it
    A white rectangle over a line of text hides it on screen and leaves every character in the file, readable by anybody who opens it in something other than a viewer. When you cover text here, that page is rebuilt as an image instead, so the words are gone. The price is that page's selectable text, and the tool says which page and which words before you save.
    What it proves
    Before you are offered anything, the finished file is re-opened from its own bytes: every edit you made must be found in it, every page must still be there, nothing may be left as an annotation when you asked for it drawn in, and the text on the pages you did not cover must still be selectable. If anything you covered is still readable, there is no download.

    About this tool

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

    No, and any tool that says it can is showing you something else. A PDF records where each glyph sits on the page, not the sentence it belongs to, so there is no paragraph to re-flow — and a line set in a font that was embedded as a subset cannot be typed into with that same font, because the glyphs you would need were never included. This tool adds to the page: cover what is wrong and put the right thing beside it.

    Is my file uploaded?

    No. This is a static page with no endpoint to upload to: the document is opened, edited, saved and checked in this browser tab. Open your browser's network panel while you use it, or disconnect from the internet once the page has loaded and watch it keep working.

    Why did my Russian text turn into a picture?

    Because the fonts built into the PDF format cannot encode it. The alternative to drawing those characters with your browser's own font is refusing to let you type your own name, which is not an editor. The result looks and prints correctly; what it is not is selectable or searchable text, and the tool says so at the moment it happens rather than leaving you to find out.

    What is the difference between the two save options?

    Drawn into the page is the default: your edits become part of the page's own content, so software that ignores or strips annotations cannot lose them. Keep editable leaves them as annotations, which most readers show and print, and which you or anybody else can move or delete later. Choose the first to send the file, the second to come back to it.

    Is the signature I draw a legal electronic signature?

    No, and this site will not claim otherwise. What you draw is a picture of your name placed on the page, which is what most people mean and what most documents ask for. A cryptographic signature needs an identity authority and an audit trail, and neither can exist on a device that talks to nobody — so this tool does not offer one.

    How do I add my signature to a PDF?

    Choose the signature tool, draw your name in the box with a finger, a stylus or the mouse, then drag on the page where it should go. It is placed as a picture of your signature and drawn into the page when you save, so it prints and travels like the rest of the document. It is not a cryptographic signature and this site does not claim otherwise.

    How do I add text to a PDF?

    Type the words in the field, then drag a box on the page where they belong — the box is the size, so a taller box gives bigger words. You can move it, resize it from the corner, change its colour and undo. When you save, the words are drawn into the page itself rather than left as an annotation another program could ignore.

    Can I edit a password-protected PDF?

    Not directly. Remove the password with the unlock tool on this site — you will need the password the file opens with — and edit the copy it gives you. If you want the result protected again, the protection tool will encrypt it with a new password.
