Manip
Batch Image Processing for macOS
Manip is a native Mac app for batch image processing. Drop in any number of photos, build a pipeline of operations, watch a live preview update as you work, then export — at every size you need — in one click.
Built for Real Workflows
- Photographers prepping a shoot for web, print, and social.
- Developers generating @1x, @2x, and @3x assets from one source.
- Online sellers watermarking and resizing product photos before upload.
- Designers batch-exporting icons, screenshots, and hero images.
Manip handles all of it without writing a line of code or touching a command-line tool.
Twenty Operations. One Pipeline.
Add as many rules as you need, in any order. Manip applies them in sequence to every image in your batch.
Transform
- Resize — fit within bounds, fill and crop, exact dimensions, scale by percentage
- Crop — trim to aspect ratio (1:1, 4:3, 16:9, and more) or fixed pixel size, with a 9-point anchor
- Rotate — 90°, 180°, or any custom angle
- Flip — horizontal or vertical mirror
Colour & Tone
- Adjust Colour — brightness, contrast, saturation, hue, exposure, and vibrance
- Temperature & Tint — white balance correction
- Highlights & Shadows — targeted tone curve adjustments
- Sharpen — unsharp mask with radius and intensity
- Noise Reduction — smooth grain without losing detail
- Blur — Gaussian soft-focus effect
Style & Finish
- Grayscale — instant black and white
- Sepia — warm vintage tone with adjustable intensity
- Vignette — darken edges for a moody, cinematic look
- Canvas — extend the image with configurable padding and a background colour
- Border — add a coloured frame with optional rounded corners
- Watermark (Text) — overlay any text at any position, font, size, colour, and opacity
- Watermark (Image) — overlay a logo or graphic at configurable size and opacity
Export & Utility
- Convert Format — JPEG, PNG, TIFF, HEIC, or WebP with quality control
- Strip Metadata — remove EXIF, GPS, and IPTC data in one step
- Remove Background — on-device AI foreground extraction using Apple's Vision framework
Live Preview — Always Watching
A dedicated preview panel shows the exact result of your full pipeline on the selected image, updating in real time as you tweak any setting. No guessing. No batch-and-check cycles.
Export Multiple Sizes in One Run
Define output size variants once and Manip generates all of them per file: @1x and @2x for web, a thumbnail and a full-size for your shop, a square crop and a 16:9 for social — whatever you need. One click processes every file at every variant simultaneously.
Eleven Built-In Presets
Jump-start common workflows: Web Export, Square Thumbnail, Retina Web (@1x + @2x), App Icon Prep (1024×1024), Email Attachment, Blog Hero, Print Ready, Profile Photo, and more. Or save any rule stack as your own named preset for instant reuse.
Undo the Whole Batch
Made a mistake? Undo moves every output file from the last run to the Trash, restoring your originals, in one action.
Native and Private
Manip is a native Mac app built in SwiftUI. All processing happens on your Mac using Core Image and Apple's Vision framework — no cloud uploads, no subscription, no account required. Your images never leave your machine.
