About FirmApp: Llenar y Firmar PDF

FIRMAPP - THE 100% LOCAL AND FREE PDF SCANNER, CONVERTER, AND SIGNATURE

FirmApp is the ultimate Swiss Army knife for managing your PDF documents securely, with an ultra-lightweight and free interface, no subscriptions, and no ads. Its cornerstone is Absolute Local Processing: everything happens on your phone. Your files, contracts, and signatures are never uploaded to the internet or third-party cloud services, guaranteeing complete privacy.

UNIVERSAL CONVERSION WITHOUT LIMITS
Instantly transform any file into a perfect, high-fidelity PDF, preserving the original fonts, tables, graphics, and designs without altering the document:

• Word documents (.docx, .doc): Maintains the exact hierarchy, indents, and alignment.

• Excel spreadsheets (.xlsx, .xls): Aligns financial reports and price lists within the margins.

• PowerPoint Slides (.pptx): Convert your presentations to a seamless, professional format.

• Plain Text Files (.txt) and Images (.jpg, .png): Convert notes or screenshots instantly.
Working locally, you convert at lightning speed without needing Wi-Fi or a network signal, completely saving your mobile data plan.

BUILT-IN PDF EDITOR
FirmApp isn't just a viewer; it's a dynamic editor that lets you modify and refine your files directly on your device:

• Touch Rearrange: Drag and drop PDF pages to change their order in seconds.

• Page Cleanup: Remove duplicate pages, drafts, or irrelevant attachments before sending the file.

• Merge and Customize: Combine elements and streamline your entire workflow in one place.

FIRMAPP: THE SMART SCANNER
Digitize physical paper with office-quality scanning using local computer vision algorithms:
• Automatic edge detection: Identifies paper contours and instantly cuts out the background.

• Perspective correction: Three-dimensionally straightens photos taken at awkward angles.

• Digital enhancement filters: Eliminates shadows and blemishes, leaving a pure white background and crisp, high-fidelity black text for maximum legibility.

VECTORAL HANDWRITING SIGNATURE
Print premium signatures on your contracts, receipts, or reports directly with your finger or a stylus:
• Vector capture: Your signature is stored with high-resolution mathematical curves. It remains smooth, fluid, and defined no matter how much you zoom in, eliminating pixelated or blurry strokes.

• Dynamic positioning: Drag, scale, and precisely position the signature on any coordinate or page of the PDF.

• Privacy Bunker: Your signature is your legal identity. Processed securely within your phone's memory, your signed documents never leave your control, protecting you from online hacking.

HIGH-PRODUCTIVITY DESIGN
Inspired by the market's most modern and clean aesthetic standards (Notion or Linear style):
• Smart Tags: Color-code your PDFs to find contracts or invoices in a snap.

• True Light and Dark Modes: Precisely optimized for AMOLED/OLED screens. Reduces battery consumption and drastically decreases eye strain during nighttime use.

• Ultra-Lightweight: Takes up minimal storage space on your phone and doesn't consume RAM in the background, ensuring seamless performance on high-end, mid-range, or low-end phones.
