What You Can Actually Do to a PDF Without Acrobat
Browser-based PDF editors support the most common annotation and markup tasks: adding text boxes, drawing freehand shapes, inserting highlights, adding image stamps, and placing checkmarks or circles. They do not replace the source content of a PDF the way a Word editor modifies a document. If you need to change the body text of an existing PDF, converting to Word first and then back is the better workflow.
How to Add Text to a PDF Online
Open the ToolMint Edit PDF tool. Upload your PDF. Select the text tool and click anywhere on the page to place a text box. Type your content, adjust the font size and color, and drag the text box to the right position. This is useful for filling in form fields that are not interactive, adding captions or labels to diagrams, or inserting a date into a document before sending.
Highlighting and Drawing on a PDF
Use the highlight tool to mark important passages by dragging across text. Use the pen or shape tools to circle, underline, or annotate specific areas. These features are especially useful for reviewing contracts, marking up job application documents, or providing feedback on design files received as PDFs.
Adding an Image or Signature Stamp
You can insert an image stamp anywhere on a page — useful for placing a scanned signature, a company logo, or a copy of a physical stamp. For signatures specifically, the Sign PDF tool provides a cleaner workflow where you can draw, type, or upload a signature and position it precisely on the signature line of a document.
When to Convert Instead of Edit
If you need to make structural changes — rewriting paragraphs, reshuffling content, or resizing tables — editing the PDF directly is not the right tool. Convert the PDF to Word using PDF to Word, make the changes, and then convert back using Word to PDF. For scanned PDFs, OCR must run first before text can be extracted or searched. Use PDF to Text to extract the content into an editable format.
