Morpholder: Rename to Convert
Image, Video & Audio Converter
Only for Mac
$14.99
Mac
Rename any file to convert it. AI upscaling, background removal, 50+ formats — all automatic, all local. No dialogs. No clicks.
Morpholder is the only file converter on Mac with no interface to open. Rename a file in Finder - it converts instantly in the background.
HOW IT WORKS
Drop any folder into Morpholder's Menu Bar icon. From that moment, simply rename a file's extension in Finder to trigger conversion. Change photo.jpg to photo.png, rename clip.mov to clip.mp4 - Morpholder intercepts the rename and converts automatically. No export dialogs. No apps to switch to. Just rename.
MAGIC SUFFIXES - POWERFUL TOOLS IN ONE RENAME
Beyond format conversion, add a suffix to the filename to trigger advanced processing:
• _upscale_4x or _upscale_2x - AI upscale on your Neural Engine
• _nobg - Remove background instantly with Apple Vision
• _smartcrop_1x1 - Smart crop to any ratio with face & subject detection
• _nometa - Strip EXIF, GPS, shooting data, and all metadata
• _720p / _1080p / _4k - Resize video to any resolution
• _mute - Remove audio track without re-encoding
• _trim_0.30_2.15 - Trim video to exact timestamps
• _speed_2x - Speed up or slow down any video or audio
• _base64 - Encode any file to Base64 text, or decode back
Combine multiple suffixes for instant pipelines: rename photo_upscale_4x_nobg.png to upscale and remove background in one step.
