About this app

Fill out, sign, and send any PDF form right from your phone — no printer, no scanner, no computer needed. PDF Filler is a fast, free PDF editor and signature app for real people who get a form on WhatsApp, Gmail, or Files and just need to fill it in, sign it, and send it back in minutes.

Everything happens on your device. Your documents never leave your phone, there is no sign-up or account, and the finished PDF comes out clean — with NO watermark.

★ FILL PDF FORMS
• Open any PDF from Files, WhatsApp, Gmail, or any app via “Open with”.
• Tap and type directly on the form — name, address, email, any detail.
• Add today’s date with a single tap, or pick any date.
• Move, resize, and recolour anything you add (black, blue, green, red).
• Tick boxes with checkmarks (✔) and crosses (✖).
• Pinch to zoom for the fiddly bits and swipe through multi-page PDFs.

★ SIGN PDF — DIGITAL SIGNATURE
• Draw your signature with your finger and reuse it on every form.
• Type your name in a handwriting-style signature font.
• Upload a signature photo or snap one with your camera — the paper background is removed automatically for a clean, transparent signature.

★ DRAW, HIGHLIGHT & MARK UP
• Freehand draw and highlight text.
• Add shapes: line, arrow, circle, and rectangle.
• Blackout to redact sensitive information.
• Drop sticky notes and comments.
• Add a photo — a passport picture, ID, or any image — then position and resize it.

★ SAVE & SHARE
• Auto-saved drafts — stop and finish later.
• Rename the file before you send it.
• Download to your phone, or share instantly to WhatsApp, Gmail, or anywhere. The exported PDF is flattened and ready to send.

WHY YOU’LL LOVE IT
• 100% offline — fill and sign PDFs with no internet. Your files stay private on your phone.
• No watermark — the exported PDF is completely clean.
• No sign-up, no account, no subscription.
• Free and easy — anyone can use it the very first time.

PERFECT FOR
Application forms, bank and KYC forms, school and admission forms, rent and lease agreements, consent and declaration forms, job forms, government forms, tax forms, and contracts — anything that arrives as a PDF.

PRIVACY FIRST
PDF Filler processes your PDFs entirely on your device. We do not upload, collect, or store your documents or personal information on any server. The app uses the internet only to show a single ad when you download or share a file.

This app is free and ad-supported. A short, full-screen ad may appear when you download or share your completed PDF. If the ad cannot load or you are offline, your file is still saved and shared normally.

Open a PDF and get it done — fill, sign, and send in minutes.
