Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Saves where you expect
• Knack now asks once for permission to save next to your originals, then remembers it, even after a restart. No more picking the output folder every time.
Errors that make sense
• When a file can't be processed, Knack tells you which file, why, and what to do about it.
Real JPEG compression
• Image Compressor now shrinks JPEGs, often by 80% or more, with no visible difference.
Safer batches
• Running again only processes new or failed files.
• Cancel stops right away.
• Files with the same name never overwrite each other.
Right-click in Finder
• Remove Background, Compress, Extract Text and Convert are in Finder's Services menu. Turn them on in Settings → Finder integration.
Plus dozens of smaller fixes and polish throughout.
