Is Practical Web Tools really free?

Yes, all 300+ tools are completely free with no hidden costs. There are no premium tiers, no usage limits, and no subscriptions. The AI chat feature is also 100% free because it runs on your own computer using Ollama.

Are my files uploaded to your servers?

No. All file processing happens directly in your browser using WebAssembly technology. Your files never leave your device. This makes Practical Web Tools ideal for sensitive documents like contracts, medical records, and financial statements.

What file formats can I convert?

Practical Web Tools supports PDF conversion (to Word, Excel, PowerPoint, images, text), image formats (JPG, PNG, WebP, HEIC, GIF, BMP), audio formats (MP3, WAV, FLAC, OGG, M4A, AAC, OPUS), and document compression (ZIP, 7Z, GZIP, RAR).

How does the free AI chat work?

The AI chat uses Ollama, a free open-source tool that runs AI models locally on your computer. After a one-time setup (about 5 minutes), you can chat with models like Llama 3.2 and Mistral completely offline. Your conversations are never sent to any external servers.

Do I need to create an account?

No account or signup is required. All tools work immediately with no registration. For AI chat, you just need to install Ollama once on your computer.

Is there a file size limit?

Most tools handle files up to 100MB. Since processing happens locally in your browser, the actual limit depends on your device's memory. For very large files, we recommend using our Split PDF or Compress Files tools first.

Does it work on mobile devices?

Yes. All file conversion tools work on smartphones and tablets. The AI chat feature requires a desktop computer (Windows, Mac, or Linux) because Ollama needs to run locally.
