File Converters

Convert between image formats (PNG, JPG, WebP, SVG), documents (PDF, DOCX), data formats (JSON, XML, YAML, CSV), and more. All conversions happen locally in your browser.

Generators

Generate QR codes, barcodes, UUIDs, secure passwords, hash values, DevOps configs (Docker, Kubernetes, CI/CD), and guild emblems for MMORPGs.

Editors

Edit images, PDFs, signatures, and text files. Merge and split PDFs, remove EXIF data from photos, create digital signatures, and manipulate text.

Validators

Validate JSON, XML, YAML syntax, test regular expressions, verify credit cards, IBANs, emails, and check security credentials.

Formatters

Beautify and format JSON, XML, SQL, JavaScript, CSS, HTML, and YAML code. Clean up messy code with proper indentation.

File Viewers

View ZIP, 7z, ISO archives, CAD files (DXF, STL), medical images (DICOM), spreadsheets, and specialized formats without installing software.

Calculators

Calculate percentages, aspect ratios, RAID storage capacity, reading time, word frequency, and gaming stats.

Encoders

Encode and decode Base64, URL strings, HTML entities, and text ciphers. Convert between different encoding formats.

Decoders

Decode JWT tokens, SAML assertions, OAuth tokens, SSL certificates, QR codes, and barcodes. Inspect encoded data.

Why Use ToolsDock?

Unlike traditional online tools that upload your files to remote servers, ToolsDock processes everything directly in your web browser using modern JavaScript APIs. Your sensitive documents, images, and data never leave your device.

  • Privacy-First Architecture: All file processing uses client-side JavaScript. No server uploads, no data collection, no tracking.
  • Works Offline: Most tools continue working even without an internet connection after initial page load.
  • No Account Required: Use any tool immediately without creating an account, verifying email, or providing personal information.
  • No File Size Limits: Process files as large as your browser can handle—typically hundreds of megabytes.
  • Open Standards: Built on Web APIs like Canvas, File API, Web Workers, and WebAssembly for maximum compatibility.

How Browser-Based Tools Work

  1. You select a file from your computer using the file picker
  2. JavaScript reads the file directly from your local storage
  3. Processing happens entirely in your browser's memory
  4. The result is generated and made available for download
  5. No data is ever transmitted to any server

Technical note: ToolsDock uses the File API, Canvas API, and Web Workers for heavy computations.

Frequently Asked Questions

Yes, all tools on ToolsDock are completely free to use with no hidden costs, premium tiers, or usage limits. We don't require account creation or payment information. The tools are sustained through minimal, non-intrusive advertising.

Your data is completely safe. ToolsDock processes all files locally in your browser—nothing is uploaded to our servers. We have no ability to see, store, or access your files. This architecture is fundamentally different from most online tools that require server uploads. You can verify this by using browser developer tools to monitor network traffic while using any tool.

Once a ToolsDock page loads, all the code needed to run the tool is already in your browser. Since processing happens locally using JavaScript (not on a remote server), most tools continue working even if you lose your internet connection. This is especially useful for converting files or generating codes while traveling.

ToolsDock works in all modern browsers including Chrome, Firefox, Safari, and Edge. We use standard Web APIs supported by all major browsers. Some advanced features like WebAssembly-based tools may require recent browser versions. For the best experience, we recommend keeping your browser updated.

Since processing happens in your browser, the limit depends on your device's available memory rather than server restrictions. Most modern computers can handle files up to several hundred megabytes. For very large files (500MB+), ensure you have sufficient RAM and consider closing other browser tabs to free up memory.

Yes, ToolsDock is fully responsive and works on smartphones and tablets. The interface adapts to smaller screens, and all core functionality remains available. However, processing very large files may be slower on mobile devices due to limited memory and processing power compared to desktop computers.
