PDF Text Edit-Kun
Rewrite, Sign & Fill. Offline
Free · In‑App Purchases · Designed for iPad
Edit the actual text inside your PDFs. Change color, size and font, add signatures, fill forms, and organize pages. Everything stays on your device.
PDF Text Edit-Kun: edit the actual text inside your PDFs, right on your iPhone or iPad.
Need to fix a date, an amount, or a typo in a receipt, contract, or form? PDF Text Edit-Kun rewrites the text itself instead of turning the page into an image, so the original layout stays intact. Everything happens on your device. Your files are never uploaded.
■ KEY FEATURES
• Edit text in place
Rewrite, add, delete, and move text inside your PDFs. Tap a text block, edit it, and see the result right away.
• Change color, size, and font
Switch between Text, Color, and Size tabs for the text you selected. Choose from preset colors or any custom color, set the size in points, and pick a font (including your own font files).
• Sign and fill forms
Create a signature from your name and place it anywhere on the page. Fill in form fields, checkboxes, and radio buttons in PDFs that have them.
• Organize pages
Delete and reorder pages, and merge several PDFs into one.
• Passwords and properties
Set or remove open and edit passwords. Edit the title, author, subject, and keywords.
• Compare before and after
Flip between the original and your edited version with one tap.
• Save over the original
Choose Save and Close to overwrite the PDF you opened, with no file picker. Or export a copy instead.

PDF Text Edit-Kun works fully offline. Your documents never leave your device, so sensitive files are safe to edit.
