We Love PDF System Requirements Document

Introduction

The "We Love PDF" project aims to develop a fully functional replica of the "I Love PDF" platform, focusing on delivering a simple and minimalistic user interface and user experience. This document outlines the system requirements necessary to achieve this goal.

System Overview

"We Love PDF" is a web-based application designed to provide users with a suite of PDF-related tools, including merging, splitting, compressing, converting, and editing PDF files. The project emphasizes simplicity and minimalism in its design to ensure ease of use for all users.

Functional Requirements as Story Points

• As a User, I should be able to upload PDF files for processing.
• As a User, I should be able to merge multiple PDF files into a single document.
• As a User, I should be able to split a PDF document into multiple files.
• As a User, I should be able to compress PDF files to reduce their size.
• As a User, I should be able to convert PDF files to other formats (e.g., Word, Excel, JPG).
• As a User, I should be able to convert other formats (e.g., Word, Excel, JPG) to PDF.
• As a User, I should be able to edit PDF files, including adding text, images, and annotations.
• As a User, I should be able to download the processed PDF files.
• As a User, I should be able to access the platform from any device with an internet connection.

User Personas

• Regular User: Individuals who need to perform basic PDF operations such as merging, splitting, and converting files.
• Professional User: Users who require advanced PDF editing capabilities for professional or business purposes.

Core User Flows

• User uploads PDF file(s) -> selects desired operation (merge, split, compress, convert, edit) -> processes file(s) -> downloads the result.
• User accesses the platform -> selects a tool -> follows on-screen instructions to complete the task -> downloads the processed file.

Visuals Colors and Theme

• text_muted: #95A5A6 (Muted Gray)
• border: rgba(44, 62, 80, 0.2)

Signature Design Concept

The homepage of "We Love PDF" will feature an interactive PDF transformation journey. Users will see a dynamic, animated workflow where PDF files are visually represented as sheets of paper. These sheets will move through a series of animated stations, each representing a different PDF tool (merge, split, compress, etc.). As users hover over each station, the paper will transform to illustrate the tool's function (e.g., splitting into multiple sheets, merging into a single stack). This engaging visual will be created using motion/react for smooth animations and transitions.

Landing Hero Motion Brief

The landing hero will depict a seamless transformation of a PDF document. Users will see a PDF icon that, upon interaction, transforms into a series of animated actions (e.g., merging, splitting) and finally resolves into a polished PDF document ready for download. This animation will loop every 10 seconds, providing a clear narrative of the platform's capabilities. The animation will be responsive, adjusting to different screen sizes while maintaining clarity and engagement.

Interaction Model & Motion Direction

The intended interaction model for the landing page is "animated." This will include moderate scroll-triggered reveals, hover transitions, and spring physics on interactive elements, ensuring a polished and engaging user experience.

Non-Functional Requirements

• The application must be responsive and accessible on all major web browsers and devices.
• The system should handle multiple concurrent users without performance degradation.
• The platform must ensure data security and privacy for all uploaded files.
• The application should have a high availability rate, with minimal downtime.

Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, using Alembic for migrations
• AI Models: Not applicable
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The platform will primarily serve users in India, considering local preferences and internet conditions.
• The application will not include AI-based features unless specified in future updates.
• The system will adhere to local data protection regulations.

Glossary

• PDF: Portable Document Format
• UI/UX: User Interface/User Experience
• Responsive Design: A design approach that ensures a website looks good on all devices
• Concurrency: The ability of a system to handle multiple operations simultaneously
