Common use cases
- Quick one-off jobs when you don’t want to install desktop software
- Privacy-sensitive files you’d rather not upload to a random website

- Sharing a free link with teammates who need the same security utility
Tips for better results
- Start with a copy of important files so you can re-run with different settings
- For large PDFs or images, close other heavy tabs to free memory
- Prefer WebP or optimized settings when size matters more than lossless quality
- After processing, verify the output (page count, text, image quality) before sharing
Privacy & limits
AllToolHub focuses on local, browser-based processing. Your device does the work; there is no account system required to use tools.
Limits are usually your browser and device memory—not a cloud plan. Extremely large files may need a desktop app or splitting the job into smaller batches.
FAQ
Can I make a Wi‑Fi QR code?
Yes. Choose the Wi‑Fi type, enter SSID, password, and encryption — phones can join by scanning the code.
Can I generate QR codes offline?
After the page loads, generation runs in the browser. Keep a network connection for the first visit so scripts can load.
