// FAQ
What can I edit in a PDF with this tool?
You can add text anywhere on any page, draw freehand signatures, insert shapes and highlights, place images, redact sensitive content, and reorder, rotate, or delete pages — all directly in your browser.
Can I sign a PDF with this editor?
Yes. Select the DRAW tool and sign directly on the page with your mouse, trackpad, or touchscreen. Your signature is rendered as freehand ink and baked into the final PDF when you save.
Are my files uploaded to a server?
No. All processing happens entirely in your browser using JavaScript. Your PDF never leaves your device. Nothing is sent to any server — it is 100% local and private.
Can I add images or logos to a PDF?
Yes. Use the IMAGE tool to upload a PNG or JPEG, then click on the page to place it. You can move and resize the image before saving.
How do I redact or black out text in a PDF?
Select the REDACT tool and draw a rectangle over the content you want to hide. When you save, a solid black rectangle is permanently burned into the PDF, covering the original content.
Can I reorder or delete pages?
Yes. The page sidebar shows thumbnails of every page. Use the up/down arrows to reorder pages, the rotate button to rotate them, or the delete button to remove pages. You can also add blank pages.
