Most "free online tools" share a quiet catch: you upload your file to someone's server. For a throwaway screenshot that's fine. For a contract, an API key dump, a customer spreadsheet or a private PDF, it's a problem.
Gealo's microtools take the opposite approach. They run entirely in your browser. Nothing is uploaded, nothing is stored, and most of them work offline once the page has loaded. No account required.
What you can do without signing up
- Documents: convert Markdown to PDF or HTML, edit front matter, view DOCX/PPTX/EPUB/RTF, extract PDF text, split and reorder PDF pages.
- Spreadsheets: convert XLSX to CSV/JSON, merge and manage sheets, edit metadata, redact cells.
- Images: compress, convert, crop, remove backgrounds, read EXIF, build sprite sheets and favicons.
- Audio & video: trim, convert, mute, turn video into GIFs, extract audio.
- Developer utilities: regex tester, hash generator, X.509 certificate decoder, WebSocket tester, CSS gradient and color-palette builders, text and Markdown diffing.
Why client-side matters
When the work happens in your browser, three good things follow:
- Privacy. Your file never touches a server, so there's nothing to leak, log or subpoena.
- Speed. No upload, no download, so large files don't have to make a round trip.
- Resilience. Once loaded, many tools keep working with no connection at all.
How this connects to the rest of Gealo
The microtools are a genuinely free, no-strings front door. The same care that keeps your files on your machine is the care we put into keeping each workspace's data isolated inside the full product. If you outgrow the tools and want tasks, chat, meetings and GitHub sync in one place, the features page shows what that looks like.
