Toolora — 41 Free Online Tools That Never Upload Your Files

Toolora is a privacy-first browser-based toolkit with 41 free tools covering PDF manipulation, image processing, text utilities, developer helpers, and AI-ready workflows. Every tool runs entirely inside your browser using WebAssembly and native browser APIs. Your files never leave your device — not even for a millisecond.

PDF Tools — Merge, Split, and Extract Without Uploading

The PDF Merger lets you combine multiple PDF files into one document by dragging them into order and clicking merge. The PDF Splitter extracts individual pages or page ranges from any PDF. Both tools process files using pdf-lib running inside your browser — no server receives your documents. This makes them safe for confidential contracts, medical records, and legal filings.

Image Tools — Compress, Resize, and Convert Privately

The Image Compressor reduces JPG, PNG, and WebP file sizes without visible quality loss using the browser Canvas API. The Image Resizer changes dimensions by pixel count or percentage while preserving the aspect ratio. The Image Converter changes formats between JPEG, PNG, and WebP instantly. None of these tools transmit your images anywhere.

Developer Tools — Hash, Encode, Format, and Test

Toolora offers a full suite of browser-based developer utilities: a JSON Formatter and validator with error detection, a Hash Generator producing MD5, SHA-1, SHA-256, and SHA-512 outputs, a JWT Decoder that reveals header, payload, and expiry status, a Regex Tester with live match highlighting and capture group display, a Base64 Encoder and Decoder, a URL Encoder and Decoder, a YAML-to-JSON Converter, a Cron Expression Parser that translates schedules to plain English, a Number Base Converter for decimal, binary, octal, and hexadecimal, and a String Escape Tool for JSON, SQL, regex, CSV, shell, and XML.

The Token Counter is particularly useful for developers working with large language models. It supports the exact tokenization algorithms used by GPT-4o, GPT-4, Claude 3.5, and Llama, letting you see precisely how many tokens a prompt will consume and what percentage of a model's context window it fills — before you make an API call.

AI and RAG Workflow Tools

The Text Chunker splits long documents into overlapping segments ready for vector database ingestion. You choose between paragraph-boundary, sentence-boundary, or fixed-character chunking, and set both the chunk size and the overlap between adjacent chunks. Output can be downloaded as a plain text file or as JSONL with token estimates per chunk — ready for Pinecone, Weaviate, Chroma, or any embedding pipeline.

The HTML to Markdown Converter cleans scraped web content into readable Markdown suitable for LLM prompts. It handles headings, bold, italic, tables, code blocks, ordered and unordered lists, and links. The AI Data Extractor uses GPT to pull structured JSON from any unstructured text — describe what fields to extract in plain English and get back clean, typed output from emails, contracts, meeting notes, or product pages.

The Document Memory Loader is the most advanced tool: upload a PDF, DOCX, or text file and it is automatically chunked and saved to Toolora's persistent memory system. The next time you open Claude with Toolora's MCP server connected, your document is immediately available for questioning — with no re-uploading and no vector database required.

Free MCP Server for Claude, Cursor, and Windsurf

Toolora runs a free Model Context Protocol (MCP) server at toolora.dev/api/mcp with 25 tools. Add one configuration block to Claude Desktop, Cursor, or Windsurf and your AI agent can call PDF text extraction, HTML to Markdown conversion, text chunking, regex execution, hash generation, token counting, structured data extraction, QR code generation, and persistent memory — all without an API key. The server is listed in the Anthropic MCP registry.

Why Toolora Instead of Other Free Online Tools

Most free online tools process files on a remote server. Your document is uploaded, processed, and — depending on the service's privacy policy — potentially stored, logged, or shared. Toolora's architecture makes this technically impossible for browser tools: there is no upload request to intercept because no upload happens. You can verify this in any browser's DevTools by opening the Network tab while using any tool — you will see no outbound file transfer.

Toolora is built for developers, legal professionals, healthcare teams, financial services firms, and any individual who needs to process sensitive documents without exposing them to third-party infrastructure. All 41 browser tools are free, require no account, and work offline once the page has loaded.
