Frequently asked questions
Can I convert a whole folder at once?
Yes, drop in a batch of files or a whole folder and FlipConvert converts everything in parallel across your CPU cores.
Will it overwrite my original files?
No. Converted copies are written next to the originals or to a folder you choose, and existing files are never overwritten; a numbered copy is created instead.
Does HEIC conversion need anything extra installed?
It uses the Windows HEIF Image Extensions, a free Microsoft add-on preinstalled on most modern PCs; FlipConvert tells you if it is missing.
Can it edit video too?
Yes, lossless trim, remux to a different container, and audio extraction, all as stream-copy operations with no quality loss and no re-encoding wait.
Is there a file size limit?
No.
