About this app

Got a PDF form on your phone? Type into it, tick the boxes, sign it with your finger and send it back. No account, no upload and no monthly fee to fill in a form.

FREE NOW, PRO LATER
Every feature is free right now. A Pro version is coming, so this app will not stay free forever. Everyone who installs it now keeps every feature free for good, including any Pro features we add later.

FILL IN FORMS
• Type into any fillable PDF, tick boxes and pick from lists.
• Save a copy or send it straight to email, Drive or any app.
• Open PDFs from email, Files or Drive with "Open with Oexta PDF".

SIGN
• Draw your signature with your finger or type it.
• Place it anywhere on the page, resize it, and undo if it is not right.

SIGN AND LOCK
• Add a real digital signature made with your own certificate.
• Lock the document so nobody can change it after you sign.
• Use a certificate you bought from a provider (.p12 or .pfx file), protected with your password.

CHECK SIGNED PDFs
• Open a signed PDF and see who signed, when, and whether it was changed afterwards.

MAKE FORMS
• Add text boxes, check boxes and drop downs to any PDF so other people can fill it in.

PRIVATE BY DESIGN
• No account. Your PDFs and certificates stay on your device.
• Nothing is uploaded. Files leave only when you send them.

Made for parents signing school forms, renters, freelancers and small offices.
