Can I edit scanned PDFs?
You can add text, signatures, and annotations on top of scanned PDFs. However, the scanned text itself cannot be edited directly as it's an image. For editing scanned text, you would need OCR software to convert the image to editable text first.
How to edit PDF without losing formatting?
Our PDF editor preserves your original document formatting. When you add text, signatures, or annotations, they're layered on top of the existing content without altering the original layout. The downloaded PDF maintains all original formatting plus your additions.
Can I edit the existing text in a PDF?
Our tool allows you to add new text anywhere on the PDF and cover existing text with white shapes if needed. For true text editing (modifying existing characters), you would need the original source document or use our PDF to Word converter for extensive edits.
Is it safe to edit sensitive documents online?
Absolutely. All file processing happens directly in your web browser using JavaScript. Your documents are never uploaded to our servers, ensuring complete privacy and security for sensitive forms, contracts, tax documents, and personal information.
Will there be watermarks on my edited PDF?
No, never. Unlike many free PDF editors that add watermarks, PDFUtilKit produces clean PDFs without any watermarks, branding, or limitations. Your edited documents look completely professional.
Can I add multiple signatures to one document?
Yes! You can add as many signatures as needed throughout the document. This is useful for multi-page contracts, legal agreements, or forms that require signatures and initials on multiple pages.
What types of annotations can I add?
You can add highlights (various colors), underlines, strikethrough, text boxes, sticky notes, shapes (rectangles, circles, lines), arrows, and freehand drawings for comprehensive document markup and review.
Does the tool work on mobile devices?
Yes, our online PDF editor is fully responsive and works on all mobile devices including iPhones, iPads, and Android phones/tablets. Drawing signatures with your finger on touchscreens is particularly intuitive and natural.
Can I edit a password-protected PDF?
No, you need to remove password protection from the PDF before editing. Our tool respects document security and cannot bypass protection on locked PDFs. If you have the password, unlock it first in your PDF reader.
