The challenge we solve

Most PDF tools force users to juggle multiple apps for editing, conversion, translation, signatures, and OCR—often with limits, watermarks, and privacy trade‑offs. DeftPDF set an ambitious product bar:

Unify a full PDF toolbox(40+ tasks) behind a simple UX onweb and mobile.
Go beyond editingwith AI‑assisted document Q&A(“Chat with PDF”) that works on single or multiple files.
Preserve layout in document translationwhile supporting scanned PDFs via OCR, with transparent page‑based pricing.
Earn trust on privacy(short‑lived uploads, encryption in transit) and ship predictable upgrade paths for power users.

What we built for every PDF task

A unified web platform (40+ tools)

On web, users can edit text, annotate, add images, fill & sign forms, merge, compress, convert to/from Office formats, run OCR, split/extract pages, add watermarks, perform Bates numbering, and more—without watermarks. The product surfaces these capabilities in a single launcher, organized by “Edit & Sign,” “Merge & Compress,” “Convert,” and “Split.”

Premium for power users. For heavy workflows, Premium lifts throughput constraints (e.g., up to 4GB files, bulk/batch processing).

Templates & guides.A web Template Library (e.g., common US tax forms) and step‑by‑step How‑to guides shorten time‑to‑value.

AI “Chat with PDF”

Users can upload, preview, and converse with PDFs, pinpoint regions, andexport chat history. The interface advertises GPT‑4ooptions and multi‑PDF chats, giving teams a quick way to extract insights across documents. Files are transmitted over encrypted connections and are deleted after processing.

Layout‑preserving translation with OCR

The Document Translator keeps original formatting while translating documents acrossdozens of languages, including support for scanned PDFs via OCR. Transparent pricing is $1 per page on the web flow.

Native mobile apps

Android: DeftPDF’s Android app lists 50K+ downloads, in‑app purchases, and continued updates (e.g., July 22, 2024). Data Safety disclosures indicate encryption in transit and the ability to request deletion.

Outcomes & impact delivered

Coverage from simple to advanced use‑cases. With 40+ tools available in a single UI, DeftPDF addresses everyday tasks (merge, compress, sign) and specialist needs (Bates numbering, PDF/A archival, N‑Up imposition).
AI elevates productivity. Chat with PDF shortens investigation time for contracts, research, and manuals by enabling questions and multi‑file context in one place.
Global and multilingual. The app and site expose extensivelanguage options across the product and translator flow—lowering friction for international users.
Trust by design. Clear privacy posture (encrypted transfer,short‑lived files, mobile data safety disclosures) builds confidence for consumer and SMB segments.
Mobile adoption. The Android listing shows 50K+ installsand active maintenance; iOS presence with a clean privacy label supports a “use it anywhere” story.

Note on figures: Mobile metrics reflect public store listings as of September 2025; they fluctuate over time.

How CGP Systems delivered value

Product strategy: Aligned a single roadmap across web and native apps to keep features discoverable and naming consistent (e.g., Edit, Merge, Convert, Translate).
User experience: Consolidated 40+ operations into clear categories and How‑to flows that match mental models (upload → configure → apply → download/share).
Privacy & compliance posture: Implemented flows and copy that emphasize encrypted transfer and short retention, with premium plan disclosures and options to upload via Google Drive/Dropbox when preferred.
Monetization & packaging: Balanced a generous free tier with predictable paid upgrades (Premium limits; per‑page translation pricing; mobile IAPs).
Support & feedback loops: Routed “Suggest a feature / Report a bug” to a public board to speed response and visibility.
