FAQ
Are my files uploaded to a server?
No. This page has no upload channel — files are read, converted and saved entirely on your device. It even works offline.
Is it really free?
Yes. Every conversion path is free with no sign-up, no usage caps and no watermarks.
Will the quality suffer?
Lossy targets (MP3, JPEG, H.264…) re-encode at the quality you choose; lossless targets keep every pixel. Keep the defaults if unsure.
