pdfFiller

You’re staring at a stack of contracts, forms, or tax documents that need signatures, edits, and sending—but you’re away from your desk. The printer is broken, the scanner is buried, and the clock is ticking. This is the exact moment when pdfFiller by airSlate, Inc. transforms your phone from a distraction into a mobile document command center. It solves the universal business friction of handling PDFs on the go: no desktop required, no printing, no manual data entry. Instead, you get a full suite of editing, signing, and sharing tools that work directly on your Android device, turning a logistical nightmare into a three-tap operation.

Core Functionality & Mechanics

pdfFiller operates as a complete document lifecycle manager inside a single app. The primary interaction is with any PDF, image file, or scanned document imported from your device, cloud storage (Google Drive, Dropbox, OneDrive), or email attachment. Once loaded, the app provides a layered editing interface that rivals desktop software. You can add text fields, checkboxes, signatures, initials, dates, and images with precise placement and resizing. The signature module is particularly robust: you can draw, type, or upload a saved signature image, then apply it with a single tap. The app also supports fillable form detection—if a PDF contains blank fields, pdfFiller identifies them automatically and lets you tab through them like a native form.

Beyond editing, the app includes a full e-signature workflow. You can send documents to multiple recipients for signing, set signing order, add expiry dates, and track status in real time. The built-in document scanner uses your camera to capture physical paper, then applies automatic cropping and contrast enhancement to produce clean, searchable PDFs. For collaboration, you can add comments, highlight text, and use a redaction tool to permanently remove sensitive information. The app also supports PDF conversion to and from Word, Excel, and PowerPoint formats, though this requires a subscription.
