Convert Pentax PEF to HEIC on Mac.

Local file processing, by renaming the file in Finder. No converter window and no upload queue.

Finder rename

report.pefreport.heic

How the rename works

  1. 1

    Start with report.pef

    Put the Pentax PEF file in a folder RenameTo watches, such as Desktop or Downloads.

  2. 2

    Rename it to report.heic

    In Finder, change .pef to .heic, then press Return. The rename is the command.

  3. 3

    Find the HEIC beside it

    RenameTo produces the requested output and keeps a restorable backup of the original.

What happens under the hood

RenameTo reads the Pentax PEF with the appropriate local macOS media or document framework, then writes a new HEIC beside it. The file itself is not sent to a conversion server.

About the formats

Pentax PEF is Pentax's RAW format. HEIC is Apple's space-efficient camera format, which some apps still reject.

Questions, answered

Does my file get uploaded anywhere?

No. File processing happens on your Mac. RenameTo does use the network for license validation, trial activation, and update checks, but your source files are not part of those requests.

What happens to the original Pentax PEF file?

RenameTo keeps a backup before processing. Undo restores the original alongside a format-changing output and does not delete that output. If the original name is already occupied, the restored copy gets “(restored)” in its name.

Can I convert a whole folder?

Yes. Rename multiple selected files in Finder and RenameTo queues each supported conversion, with a separate result and backup for every file.

Can I run the same conversion from a script?

Yes. The CLI command is: renameto heic *.pef
