An Adapter alternative
for iPhone and Mac.
Adapter is a long-serving free desktop converter with FFmpeg under the hood, and it is dependable for video, audio, and images. MediaKit does those jobs on iPhone and Mac and adds tools for PDFs, archives, and ebooks. It estimates the output size before you run a tool and shows what you saved afterwards, and every file stays on your device.

About MediaKit
Questions
FAQ
What is a good Adapter alternative for Mac?
MediaKit runs on Mac and iPhone and covers Adapter's video, audio, and image conversions, plus PDF, archive, and ebook tools, more than 150 in all. Drop a file in and MediaKit suggests the tools that fit it. Every tool runs on your device.
Adapter is free, so why choose MediaKit?
If a free converter is all you need, Adapter is a solid choice. MediaKit keeps five tools free for good (Video Compress, Image Compress, Image Resize, Audio Convert, and PDF Compress) and charges for the rest. With Pro you get every tool, batch processing in the Queue, Recipes that save a chain of steps, and Make It Fit for a target size or platform, on iPhone as well as Mac.
Does MediaKit support the formats Adapter handles?
For everyday work, mostly. MediaKit compresses, converts, trims, and resizes video and opens MKV directly. It writes audio as M4A (AAC), WAV, AIFF, ALAC, or CAF from formats including MP3 and FLAC, and converts images to HEIC, JPG, PNG, TIFF, GIF, and WebP where your system can write it. It does not support WebM and cannot write MP3, which FFmpeg-based tools like Adapter can.
Is MediaKit on-device like Adapter?
Yes. Both convert locally and upload nothing. MediaKit makes no network requests of its own, needs no account, and has no analytics SDK. Its Privacy Manifest is on the transparency page.
Which platforms does MediaKit run on versus Adapter?
MediaKit runs on iPhone and Mac, and one purchase covers both. There is no iPad or Windows version. Adapter is a desktop converter for Mac and Windows. If you need Windows, pick Adapter. If you want the same tools on your iPhone, pick MediaKit.
How much does MediaKit cost?
Five tools are free for good, one file at a time, and your first 3 days unlock every other tool for single-file runs with no payment. Pro is $3.99/month or $22.99/year, each starting with a 3-day free trial, or $39.99 once. Adapter is free.
