Giới thiệu
AllTool.io là bộ sưu tập các công cụ hàng ngày được thiết kế để làm một việc một cách tuyệt đẹp. Không tài khoản. Không phân tích. Chỉ các tiện ích tập trung tôn trọng thời gian và dữ liệu của bạn.
Why we built this
Most online tools are wrapped in ads, trackers, and dark patterns. We wanted something different: a clean, fast, private set of tools that feel like they were designed with care. Every tool on AllTool.io runs in your browser whenever possible — your data never leaves your device unless a tool explicitly needs server-side processing (like Image to Text OCR), and even then it is discarded immediately.
What we offer
Our toolkit includes over 50 free utilities: a secure Password Generator, Passphrase and Diceware generators, UUID and QR Code generators, a Color Picker and palette tools, Text Diff, Word Counter, Case Converter, Markdown Editor, Image to Text OCR, a Chinese simplified/traditional converter, a Video Frame Extractor, a Split Bill Calculator, JSON formatting/validation/minification tools, Base64 and URL encoding/decoding, Unix timestamp conversion, a full suite of Hash generators (MD5, SHA1, SHA256, SHA384, SHA512), Image format converters (JPG, PNG, WebP), image compression and cropping, a Business Card Mockup generator, PDF tools (merge, split, protect, unlock, add text, add watermark, organize pages, edit), Color tools (picker, palette, gradient, contrast checker, image color extractor), Unit Converters for length, weight, temperature, volume, area, and more.
Privacy by default
We believe tools should not come with surveillance. Nearly every tool on AllTool.io runs entirely on your device — passwords, IDs, UUIDs, QR codes, color values, diff comparisons, word counts, case conversions, JSON processing, hash generation, image conversions, PDF operations, and unit conversions all happen locally. The only exception is Image to Text OCR, which sends your image to our server for text extraction and then discards it immediately. We never store your inputs or outputs. We do not use tracking analytics. We do not require accounts. Read our full Privacy Policy for details.
Who maintains AllTool.io
AllTool.io is built and maintained by Slight Software. We are a small team that cares about making genuinely useful, respectful software — the kind we would want to use ourselves. Every tool is designed to be fast, accessible, and free from unnecessary complexity.
