About Toolio

Toolio is a collection of free, privacy-first tools — calculators, converters, image and PDF utilities, generators, and a few fun ones. No install, no sign-up. Most tools run entirely in your browser, so your data never leaves your device. A few that need heavier processing — file conversion (e.g. Word/Excel/PowerPoint/HWP to PDF), background removal, and image-to-text (OCR) — run on our own server: your file is sent there only to process it, then deleted immediately, and is never shared with a third party.

Who makes it

Toolio is built by Pong Studio Co., Ltd (pongvn.com), part of the BANA family of small, useful products. We also publish independent blogs on tech, AI, and markets — you'll find the ones in your language linked in the footer.

Our approach

• Privacy-first — most tools process everything in your browser; the few server-side tools process your file and delete it right away.
• Free & open access — no account or paywall to use a tool.
• Fast & mostly offline — the browser-based tools work even without a connection once loaded.
• Multilingual — available in English, 한국어, Español, Deutsch, 日本語 and Tiếng Việt.
