Permute 3 -- Best All-in-One Mac Converter
Permute 3 is the most Mac-native conversion experience available. It's a drag-and-drop app that handles video, audio, image, and document conversions from a single clean interface that looks and feels like a native macOS application. Not a port. Apple Silicon native, so it runs at full speed on M1/M2/M3/M4 Macs. Batch conversion is effortless: drop a folder, select output format, walk away.

Handbrake -- Best Free Video Converter for Mac
Handbrake is Apple Silicon native and takes full advantage of VideoToolbox hardware acceleration on M-series Macs, making H.265 encoding dramatically faster than on equivalent Intel hardware. It accepts virtually every video format as input and outputs to MP4/M4V and MKV. The preset library covers common targets: iPhone, Apple TV, web, and general-purpose profiles handle most conversion needs in a single click. For Mac users with a folder of old AVI or WMV files to modernize, or anyone ripping a physical DVD library, Handbrake is the standard recommendation. Completely free, open-source, and actively maintained.
PDF Squeezer 4 -- Best PDF Converter for Mac
PDF Squeezer 4 focuses specifically on PDF optimization and conversion. compressing large PDFs, converting images to PDF, and adjusting quality settings for file-size targets. For Mac users whose primary conversion need involves PDFs, it's more streamlined than a general-purpose tool. It's a native Mac app with excellent Retina support, batch processing via drag-and-drop, and Automator/Apple Script integration for workflow automation. The compression engine is effective: a 50MB scanned document PDF typically reduces to 8-12MB without visible quality loss. Available on the Mac App Store for a one-time purchase.
Adapter -- Best Free Quick Converter for Mac
Adapter is a free, lightweight Mac app that covers video, audio, and image conversion through a simple interface. It uses FFmpeg under the hood (the same engine as many paid tools) but wraps it in a Mac-friendly GUI with drag-and-drop support. It's not as polished as Permute 3, but it's free and handles the most common conversions. MP4 to MP3, MOV to GIF, WAV to AAC. Reliably. The output quality settings are accessible but not overwhelming. For users who only occasionally need to convert a file and don't want to pay for software, Adapter handles the job cleanly without browser-based uploads or file size limits.
CloudConvert -- Best Online Option for Mac
When a Mac-native app isn't necessary. For example, when working from an iPad or needing to convert a format that no desktop app supports. CloudConvert is the most capable online option. Its 200+ format support covers edge cases that even Permute 3 doesn't handle. Because it processes files server-side, it doesn't add load to your Mac during conversion, which matters when working on a MacBook on battery. The interface works well in Safari, and converted files download directly to your Downloads folder without extra steps. The free tier is adequate for occasional use; paid plans unlock batch jobs and larger file sizes.
What to look for
What to consider
For most Mac users who regularly convert video, audio, and images, Permute 3's one-time cost and native macOS experience make it the clear first choice. If video is your only need and budget matters, Handbrake is genuinely excellent and free.
What to consider
Check for Apple Silicon native support if you have an M-series Mac. apps without native support run through Rosetta 2 and are noticeably slower for processor-intensive tasks like video encoding.
What to consider
For PDF-heavy workflows, a dedicated PDF tool like PDF Squeezer 4 or Smallpdf Pro will handle more edge cases and output options than a general converter. If your needs are occasional and varied, the free tools (Handbrake, Adapter) combined with CloudConvert's free tier cover most situations without spending anything.
