PDF Suite Documentation

What is the PDF Suite?

The Akousa PDF Suite is a comprehensive collection of 56 browser-based PDF tools that cover every common PDF operation — from merging and splitting to converting, compressing, editing, protecting, and AI-powered analysis. Every tool processes files entirely in your browser, so your documents never leave your device.

Whether you need to combine contracts into one file, extract specific pages, convert a spreadsheet to PDF, add a watermark, or ask an AI to summarize a 200-page report, the PDF Suite handles it in seconds — with zero uploads, zero registration, and zero cost.

PDF Tool Categories

• Manipulation — Merge multiple PDFs into one, split a PDF into separate files, rotate pages, reorder pages, add page numbers, extract pages, and delete specific pages.
• Conversion — PDF to Word (DOCX), PDF to Excel (XLSX), PDF to PowerPoint (PPTX), PDF to Image (PNG/JPG), PDF to HTML, PDF to Text, Word to PDF, Excel to PDF, Image to PDF, and HTML to PDF.
• Editing — Add or edit text, insert images, draw annotations, highlight passages, add stamps, fill and sign forms, flatten form fields, and crop pages.
• Protection — Encrypt PDFs with passwords, remove passwords, add visible or invisible watermarks, redact sensitive content, and digitally certify documents.

Batch Processing

Drag and drop multiple files onto the upload area, reorder as needed, and process them all with a single click. Each file is processed independently in your browser.

Frequently Asked Questions

Are PDFs uploaded to servers?

No! All 13 PDF tools process files entirely in your browser using client-side JavaScript. Your PDF files never leave your device and are never transmitted to any server. This makes our PDF suite safe for processing confidential documents, legal contracts, financial statements, and any sensitive material.

What PDF tools are available?

13 tools covering the full PDF workflow: PDF Merge (combine multiple PDFs), PDF Split (extract specific pages), PDF Compress (reduce file size), PDF to Image (export pages as images), PDF Rotate (rotate individual or all pages), PDF Watermark (add text or image watermarks), PDF Password (encrypt or decrypt), PDF to Word (editable DOCX), PDF to Excel (tabular data extraction), PDF to PowerPoint (slide conversion), Word to PDF (DOCX to PDF), PDF Repair (fix corrupted files), and PDF Page Numbers (add numbering).

Is there a file size limit?

There is no fixed file size limit since processing happens in your browser. The practical limit depends on your device's available memory (RAM). Most modern devices handle PDFs up to 100MB or more without issues. For very large files (200MB+), ensure you have sufficient free memory and close other tabs to free up resources.

Can I process multiple PDFs at once?

Yes! The PDF Merge tool lets you combine multiple PDF files into a single document — upload as many as you need and reorder them before merging. The PDF Split tool can extract specific page ranges from a single PDF into separate files. Other tools process one PDF at a time for optimal performance.

Are there any watermarks or quality limitations?

No. All PDF tools produce clean output with no watermarks, no branding, and no quality degradation. What you get is the exact processed result with full fidelity. There are no daily usage limits, no premium tiers, and no hidden restrictions — every tool is 100% free with full functionality.

How does the AI PDF analysis work?

Upload your PDF and type a question or command in the AI chat panel. The AI reads the document content and provides answers, summaries, or extracted data. Processing uses the platform's local GPU infrastructure with cloud fallback. Your document is never stored — it exists only in your browser session.

Which PDF conversion formats are supported?

The suite supports bidirectional conversion: PDF to Word (DOCX), PDF to Excel (XLSX), PDF to PowerPoint (PPTX), PDF to Image (PNG/JPG), PDF to HTML, PDF to Text, and the reverse — Word to PDF, Excel to PDF, Image to PDF, and HTML to PDF. Each converter preserves formatting as closely as possible.

Can I edit text directly in a PDF?

Yes. The PDF Editor tool lets you add new text, insert images, draw annotations, highlight passages, add stamps, and fill form fields — all within your browser. For editing existing text in a PDF, convert to Word first, make your changes, then convert back to PDF.

How does PDF compression work?

The PDF Compress tool reduces file size by optimizing embedded images, removing unused metadata, and streamlining the internal document structure. You can choose between maximum compression (smallest file) or balanced mode (good size reduction with minimal quality loss). Compression ratios of 50-80% are common for image-heavy PDFs.

Can I add a watermark to my PDF?

Yes. The PDF Watermark tool lets you add text or image watermarks to every page of your PDF. Configure the watermark text, font size, color, opacity, rotation angle, and position. You can also add watermarks to specific page ranges. The watermark is embedded in the PDF and cannot be easily removed by recipients.
