About Rakuruno
Rakuruno is a bilingual static website with practical tools for writing, calculations, images, PDFs, and everyday tasks. Our aim is to make each tool easy to use when you need it, without requiring an account.
Easy to use. Ready for real work.
Rakuruno helps you finish everyday tasks and selected creative workflows quickly in your browser. It is not a full replacement for specialist applications such as Photoshop or Acrobat.
Pro-ready is a quality label, not a paid plan. It identifies selected tools tested with realistic working data for correct results, original-file protection, safe handling of heavy workloads, clear limits, and reliable controls.
Processing speed and supported image sizes depend on your computer, browser, and available memory. Check each tool's stated limits and conditions before using large files.
What we value
- Clear controls that work well on both computers and phones
- Collecting no more information than the site needs
- Regular checks of existing tools and both language versions
How tool inputs are handled
Tool inputs are processed in your browser as described on each page. Tools with autosave use your browser's localStorage and automatically remove saved data 30 days after the most recent save. See the tool's description and our Privacy Policy for details.
Finish small tasks with a result you can check
Rakuruno is intended for everyday jobs such as cleaning whitespace or rearranging pages when opening a larger application would be unnecessary. Being able to compare the input and result matters more than asking you to trust the output blindly. Our practical guides use fictional examples to explain the steps and what to verify.
How we check and correct tools
Before release, we check both language versions, internal links, automated calculation and conversion tests, and key browser interactions. This does not guarantee identical results on every device or with every file. Browser feature support and available memory can limit some operations.
When reporting a problem, include the tool URL, browser name, expected result and actual result. Use a fictional example rather than sending personal information or confidential files. We review the report and rerun the relevant tests after a correction.
