Frequently Asked Questions
Is this PDF editor really free?
Yes — every feature is free with no watermarks, no page limits and no signup. It runs entirely in your browser using free open-source libraries.
Are my PDFs uploaded to a server?
No. Unlike many online editors, your file is processed locally on your device with JavaScript. Nothing is transmitted anywhere, so private documents stay private.
Can I edit existing text in the PDF?
Yes. Choose the Edit tool and click any existing text in the PDF — the original is covered and you can type your replacement right over it. You can also add brand-new text, highlights and annotations anywhere on the page.
How do I sign a PDF?
Click Sign, draw your signature with mouse or finger, save it, then click anywhere on the page to place it. You can drag it into position and resize the page zoom for precision.
Will annotations print correctly?
Yes. When you download, every annotation is permanently burned into the PDF pages, so the file prints and opens correctly in any PDF reader.
What's the maximum file size?
Up to 50 MB. Since everything runs on your device, very large files depend on your computer's memory — most everyday documents work instantly.
