About ConvertDa

ConvertDa is a collection of 46+ free file-conversion and utility tools — PDF merging, splitting, and compression; image and document conversion; Base64, JSON, and XML utilities — built for people who want a quick, no-signup way to get a file job done without installing software.

Why we built it this way

Most of our tools run entirely in your browser using JavaScript — your file is processed on your own device and is never uploaded to a server. For tools that genuinely require server-side processing (like OCR or LibreOffice-based conversions), files are processed temporarily and deleted automatically — see our Privacy Policy for exact details on which tools upload and how long files are retained.

How we keep tools accurate

Each tool page documents exactly what the tool does and doesn't do — file size limits, supported formats, and known edge cases — in its FAQ section, rather than overselling capability. If you find a tool behaving unexpectedly, we want to hear about it: see the Contact page.

Free, no account required

Every tool on ConvertDa is free to use with no sign-up and no usage caps. There's no premium tier gating basic functionality.
