What is an Online PDF Editor?
An online PDF editor lets you interact with a PDF document the same way you would with a physical piece of paper — flipping through pages, writing notes in the margins, circling key information, and signing where required. The difference is it all happens digitally inside your browser.
The ASAPUtils PDF editor offers freehand drawing and typed text annotation. It uses pdf.js to render the document and pdf-lib to embed your changes, and all of this runs locally on your device. No cloud account, no subscription, no file uploads.
How to Annotate or Sign a PDF
- Upload your PDF — select the document you want to edit.
- Navigate pages — use the left and right arrows to move to the page you want to annotate.
- Choose a mode:
- Pan mode — safely scroll and view without accidentally drawing.
- Draw mode — freehand drawing with your mouse, stylus, or finger. Good for signatures and circling content.
- Text mode — click anywhere on the page to place a typed text annotation.
- Customize — pick a color from the color picker and adjust the line thickness for drawn annotations.
- Clear if needed — click “Clear Page” to undo all annotations on the current page.
- Download — click “Download Annotated PDF” to embed all your edits permanently into the file.
Use Cases
- Signing contracts: Sign forms and agreements without printing, signing by hand, and scanning back.
- Reviewing documents: Mark up a draft report with comments, circles, and arrows directly on the PDF.
- Filling forms: Type your responses directly onto PDF forms that are not interactive.
- Teaching and feedback: Annotate student submissions or training materials with handwritten notes.
- Personal documents: Add notes, highlights, or reminders to reference PDFs you use regularly.
