Edit & Sign PDF

What can the LyfPDF editor do?

The editor opens any PDF right in your browser and lets you write on it: add text in any language and size, draw freehand, highlight passages, drop boxes and arrows, white-out content you want gone, and place a typed or hand-drawn signature. When you download, every annotation is flattened permanently into the file — with 0 uploads, because the whole editor runs on your device.

Editor tools at a glance

• Text — click anywhere and type; choose font family, size in points, colour and bold. Works in Hindi, Arabic and every other language.
• Sign — type your name in a script style or draw your signature, then tap to place it.
• Erase / white-out — drag a box over anything you want covered; combine with Text to replace content.
• Pen, Highlighter, Box, Arrow — annotate, mark up and point things out, with colour and thickness controls.
• Undo, Print, Download — step back mistakes, print the annotated document, or save the final PDF.

How do I fill and sign a form?

1. Open the form PDF in the editor.
2. Use the Text tool to type into each field (adjust size to fit the boxes).
3. Create your signature with the Sign tool and tap the signature line.
4. Click Download PDF — your filled, signed copy is saved to your device.

Is it safe to edit a contract or ID document here?

Yes. The editor renders pages with Mozilla’s PDF.js — the engine inside Firefox — and flattens your annotations locally on save. Because there is no upload step at any point, sensitive agreements, forms and identity documents remain solely on your device from open to download.
