Guide to 56 free PDF tools covering merging, splitting, compressing, converting, editing, protecting, and AI-powered analysis — all processing in your browser with zero uploads, zero registration, and complete privacy.
Last updated: March 2026
Select from 13 PDF tools across 4 categories: Manipulation (Merge multiple PDFs, Split into separate files, Rotate pages, Add page numbers), Protection (Password protect or remove passwords, Add watermarks), Conversion (PDF to Image, PDF to Word, PDF to Excel, PDF to PowerPoint, Word to PDF), and Recovery (Compress file size, Repair damaged PDFs).
Drag and drop your PDF files onto the upload area, or click to browse your device. For merge operations, add multiple files and reorder them as needed. All processing happens entirely in your browser — your files are never uploaded to any server, ensuring complete privacy for sensitive documents like contracts, financial records, and personal files.
Get your processed PDF instantly once processing completes. Download with one click — the result is generated entirely on your device. For conversion tools (PDF to Word, Excel, PowerPoint), the output is available in the target format ready to open in the appropriate application. No watermarks, no quality loss, and no daily usage limits.

Todo processamento acontece no seu navegador para garantir privacidade — sem upload de arquivos para servidores externos.
All 56 PDF tools run entirely in your browser using client-side JavaScript. Your PDF files are never uploaded to any server, never transmitted over the network, and never stored anywhere outside your device. This makes the suite safe for confidential documents, legal contracts, financial statements, medical records, and any sensitive material. Processing speed depends on your device's CPU and available memory.
Três modos de IA: Chat (faça perguntas sobre seu documento), Resumir (extraia pontos-chave automaticamente) e Traduzir (converta conteúdo entre 20 idiomas). Tudo alimentado pelo assistente de IA integrado.
Several PDF tools support batch operations. The Merge tool accepts unlimited files for combining. The Convert tools can process multiple files in sequence. 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.
