Getting Started with PixelTamp
PixelTamp is a native macOS desktop utility designed for instant, privacy-first media compression. It runs entirely in-process using Apple hardware acceleration and embedded compression engines. No Homebrew, no terminal commands, and no cloud uploads required.
Installation & System Requirements
PixelTamp requires macOS 26.0 or later. It runs natively and exclusively on Apple Silicon (M-series processors).
Download and install PixelTamp exclusively from the Mac App Store.
The Core Workflow
Compressing images and videos with PixelTamp takes just three steps:
1. Choose or Drop Your Media
- Drag and drop files, multiple selections, or entire folders directly onto the PixelTamp drop zone.
- Alternatively, click Choose Files… (or press
Cmd + O) to open the native macOS file picker.
2. Choose Your Options (or rely on defaults)
PixelTamp comes tuned with sensible defaults right out of the box:
- Preset: Select Tamped (balanced default), Lossless (maximum fidelity), or Aggressive (minimal file size).
- Resize: Constrain the longest dimension (e.g. 2560px, 1920px, 1024px, or Original Size).
- Format: Keep original format or convert to modern formats like WebP or MP4 video.
3. Immediate, Non-Destructive Processing
Processing begins automatically as soon as files are dropped. PixelTamp never overwrites your originals:
- By default, tamped files are written alongside the source file with a
_tampedsuffix (for example,hero.pngbecomeshero_tamped.png). - When batching is complete, click Reveal All in Finder to view your freshly compressed assets.
Privacy & On-Device Security
PixelTamp operates completely offline and on-device:
- Direct File Handling: When you drag and drop files or choose them through the native open panel, PixelTamp reads the source media directly and writes the optimised versions to your chosen output directory.
- Privacy Assurance: PixelTamp makes zero outbound network requests. With no telemetry, tracking, or cloud dependencies, your media never leaves your Mac.
