How to Compress Images and Videos on Mac and iPhone Without Losing Quality
You need to send a video but it’s 2GB. You have 500 product photos that need to be web-ready. You want to convert a folder of PNGs to WebP. Sound familiar?
I built Pressed because the existing options were either online tools (upload your files to a random server?) or command-line tools that require memorizing ffmpeg flags.
What Pressed does
Pressed is a native compression app for iPhone, iPad, and Mac:
- Image compression — PNG, JPEG, WebP, and AVIF with adjustable quality
- Video compression — MP4, MOV, and other popular formats
- Batch processing — Drop a folder of files and compress them all at once
- Format conversion — Convert between formats (PNG → WebP, JPEG → AVIF, etc.)
- Quality control — Preview before/after with a slider to find the right balance
- Watch folder automation — Set a folder to auto-compress new files (Mac)
- Custom presets — Save compression settings for repeated workflows
Why native matters
Online compression tools require uploading your files to someone else’s server. That’s fine for a meme, not fine for client photos, medical images, or anything private.
Pressed runs entirely on your device. Files never leave your Mac or iPhone. Processing uses Apple’s native frameworks (AVFoundation, CoreImage) for hardware-accelerated performance.
The numbers
A typical 4K iPhone video goes from ~400MB to ~50MB with minimal visible quality loss. A batch of 100 product photos can drop from 200MB to 15MB in seconds.
