BigQTools is a free website with 40 online tools for everyday file jobs: compressing a PDF before you email it, trimming a video clip, making a ringtone, resizing photos or opening a RAR archive. It all happens on the web, with nothing to install and no account to create.
We built BigQTools for Vietnamese users first: office workers, students, teachers, content creators and anyone who needs to get a file ready quickly for work, school or everyday life.
How it works
- Choose a tool. Pick the right tool for the job, such as Compress PDF or Trim video.
- Add your files. Choose, drag and drop or paste files from your device, pick them from Google Drive, or paste a direct link to a file.
- Get your result. Download it or save it to Google Drive. If you need to, carry on with another tool, for example compressing a PDF you just merged.
Files are processed on BigQTools servers and deleted automatically after 2 hours, or right away when you click “Delete now”.
What we stand for
- Vietnamese first. The interface, instructions and messages are written in Vietnamese from the start, with an English version alongside. OCR recognizes Vietnamese text.
- Free, with no sign-up. All 40 tools are free to use without an account, and there are no ads.
- Open about your files. We say plainly where your files are processed and how long they are kept: they are deleted after 2 hours, or sooner if you choose. The details are in our Privacy Policy.
- Accessible design. We aim for readable text, good contrast and controls that work with a keyboard and with screen readers.
- No dead links. We list only tools that work, with no placeholder pages or “coming soon” tools. If you find a broken link, please let us know.
