Why sign in?
Every tool works without an account — you never have to. But a free account remembers your work across visits:
Favorites
Save your go-to tools and jump straight to them next time.
30-day history
See what you converted — the tool, size and date, never the files themselves.
Saved preferences
Your JPEG quality, PDF compression and theme, remembered on every device.
Bigger files
Every tool's file-size limit doubles when you're signed in.
Why FileCast?
Your Files Stay Private
Most tools run entirely in your browser — nothing is uploaded. The few server-side tools convert and delete your file immediately.
No Sign-up Required
Use any tool instantly. No account, no email, no password.
No Limits, Ever
No daily caps, no file-count limits, no paywalls.
