Whether you're filling a form, marking up a contract, or adding your signature, editing a PDF shouldn't require installing bulky desktop software. I7 Pixel's PDF Editor gives you a full annotation toolkit — instantly, with nothing sent to a server.
From upload to download in four straightforward steps.
A little know-how on annotation tools goes a long way toward PDFs that communicate clearly and look professional.
Use Highlight when you want to draw attention to text while keeping it fully readable — great for reviewing contracts or marking key figures. Use Redact when you need to permanently hide sensitive information, such as an account number or personal detail, before sharing a document. Redaction covers the content with a solid block so it can't be read underneath.
The signature pad lets you draw your signature with a mouse, trackpad, or finger on touch devices, then place it directly onto the page at the exact size and position you need. This skips the usual print-sign-scan cycle entirely, so signed documents are ready to send in seconds.
Zoom in before placing small text or fine details so elements land exactly where you want them, and use the corner handles to resize rather than redrawing from scratch. If you make a mistake, Undo is faster than deleting and starting over. For multi-page documents, use the Pages panel thumbnails to confirm you're editing the correct page before adding content.
