About the PDF Editor
Toolinium's PDF Editor is a full-featured, browser-based alternative to heavyweight desktop software. Click existing PDF text to replace it; the original is covered and the replacement remains editable, add new text in multiple fonts and styles, insert images, draw your own signature, securely redact sensitive information, mark up pages with lines, arrows, shapes, checkmarks and sticky notes, attach real clickable hyperlinks, then manage your document structure — reorder pages by dragging thumbnails, duplicate, insert blank, crop, rotate or delete pages you don't need. Finish by stamping a watermark or automatic page numbers across the whole document. Every edit is rendered using your browser's own PDF engine and written back into a real PDF file with pdf-lib, so the result opens cleanly in any PDF viewer and prints or exports in one click. Nothing is ever uploaded to a server — your document, and any password you enter to unlock a protected PDF, stay on your device from start to finish.

- Click Download PDF to export, or Print to send it straight to your printer
Frequently Asked Questions
Is my PDF uploaded to a server?
No. The PDF is opened, edited and exported entirely inside your browser. Nothing leaves your device.
Can I edit the original text inside the PDF?
Yes — pick the Edit Text tool and click any line of existing text. The editor covers that exact spot and drops in an editable copy at a matching size so you can retype it, the same technique most online PDF editors use since PDFs don't store text as an editable paragraph. For anything you don't want visible at all, use Whiteout/Redact instead.
Can I reorder, insert, crop or duplicate pages?
Yes. Drag thumbnails in the left Pages panel to reorder them, and use the toolbar to duplicate the current page, insert a blank page, crop, rotate or delete pages.
How does redaction work?
Whiteout places a visual cover over content. For sensitive information, enable Secure Redaction; affected original pages are flattened before export so the underlying selectable content is not retained on those pages.
Can I sign a PDF with this tool?
Yes. Use the Signature tool to draw your signature with your mouse or finger, then place it anywhere on the page like an image.
Can I open a password-protected PDF?
Yes — upload it and enter the password when asked. Because true PDF decryption isn't available fully in-browser, the original pages are exported as sharp flattened images while anything new you add stays fully editable, selectable text.
Can I add a password to protect my PDF?
Not yet — real PDF encryption needs a dedicated library this tool doesn't include yet. Everything else, including opening and editing an already-protected PDF, works today.
Is this tool free?
Yes, the Toolinium PDF Editor is completely free with no signup required.
