Senqu Image Converter
Convert & compress, privately
Only for Mac
$4.99
Mac
Featured in Six Colors. Convert and compress images on your Mac — JPEG, PNG, HEIC, TIFF, PDF. No uploads, no subscription. Your photos never leave your device.
Senqu Converter turns image conversion into something fast, private, and pleasant. No bloated editor to learn, no uploading your photos to a website you don't trust — just drag, pick a format, and convert, right on your Mac.
Drag in a photo or a whole folder, pick a format, and convert — everything happens on your Mac. Nothing is ever uploaded to a server, so your images stay private and there are no file limits or waiting on a connection.
CONVERT
Batch-convert between JPEG, PNG, HEIC and TIFF, or combine images into a single PDF. Drop in hundreds of files at once and let Senqu work through them.
COMPRESS
Shrink file sizes with a quality slider, or set a target size and let Senqu find the best quality that fits. See exactly how much space you saved on every file. Typical screenshots compress 60-80% smaller without visible quality loss.
RESIZE & CLEAN
Scale images down to a maximum dimension, and strip EXIF and GPS metadata to remove camera and location data before you share.
PRIVATE BY DESIGN
No accounts, no uploads, no tracking, no subscription. Senqu does its work entirely on your device.
Built for people who convert images often and want a tool that's quick, clean, and respects their privacy.
