What all of these have in common
Every tool above is free, with no signup required. Most run entirely in your browser — your files never get uploaded anywhere, and the conversion happens on your own device. A small number (OCR-heavy Office conversions, PDF/A archival conversion) need server-side processing because that's the only practical way to run the software involved; those files are deleted after processing, and the tool page for each one says explicitly whether your file leaves your device.
Not sure which tool you need for a specific job? Start from the PDF Tools, Image Tools, Document Tools, or Developer Toolshub — each groups its category's tools with a short description of what each one does.
Frequently asked questions
Are all of these tools actually free?
Yes — every tool listed is free to use, with no signup required to get started.
Do any of these tools upload my files to a server?
Most run entirely in your browser and never upload anything. A small number that need software that can't run client-side (Office conversions, PDF/A archival) upload the file, process it, and delete it afterward — each tool page states this explicitly.
I don't see the exact tool I need — what should I do?
Check the category hub pages (PDF Tools, Image Tools, Document Tools, Developer Tools) — they group tools with a short description of what each does, which is often faster than guessing a tool's exact name.
