PDF Studios PDF Editor lets you mark up PDFs directly in your browser. You can add text, highlight sections, draw shapes, add comments, and redact sensitive information. Because the editing happens on your device, your file does not get uploaded to a server. It is useful for reviewing documents, adding notes, or preparing files for sharing.
Drag and drop the PDF into the editor, or click to select it. The file loads in your browser for editing.
Pick from the toolbar to add text, highlight, draw shapes, add comments, or redact content.
Click on the page to place text boxes, highlights, drawings, or black-out boxes. You can add multiple edits and move them around.
Save the updated PDF to your device. All annotations and changes will be embedded into the final file.
