Questions & answers
Is the header kept in every file?
Yes, when “First row is a header” is ticked, every split file starts with the header row.
Is it really free?
Yes. Every Feemag tool is free, with no sign-up, no watermarks added by us and no daily limits.
Are my files uploaded anywhere?
No. Your files are processed by your own browser on your device and never uploaded to a server. That also makes it fast, even on big files.
Does it work on my phone?
Yes: in any modern browser (Chrome, Safari, Edge or Firefox) on iPhone, Android, Mac, Windows and Linux.
