DaisyDisk vs MediaOptim: Honest Comparison (2026)

An unbiased look at DaisyDisk ($9.99) and MediaOptim ($49 one-time). We'll tell you when DaisyDisk is the better choice.

Quick Verdict

DaisyDisk is the best disk visualization tool on Mac—hands down. Its sunburst diagram makes it effortless to see what's eating your space. But it's diagnosis only: it shows the problem, then you have to manually delete files. MediaOptim is the treatment: it compresses your media files so they take less space without deleting anything. Ideally, you'd use both.

Detailed Breakdown

Price

DaisyDisk is $9.99 one-time—excellent value for what it does. MediaOptim is $49 one-time. They solve different problems though, so comparing price directly isn't quite fair. DaisyDisk shows you the problem; MediaOptim fixes a specific type of problem (large media files).

Features

DaisyDisk excels at one thing: visualizing disk usage. Its interactive sunburst chart is the best way to understand where your space went. MediaOptim's Space Scanner is more basic visually but directly connects to action—it finds large media files AND lets you compress them. DaisyDisk has no compression capability whatsoever.

Ease of Use

Both are excellent. DaisyDisk is arguably one of the most intuitive Mac apps ever made—scan, look at the pretty chart, drag to delete. MediaOptim is also straightforward: scan for large media, select, compress. DaisyDisk wins on visual polish.

Privacy

Both work locally. DaisyDisk scans your entire filesystem but doesn't upload anything. MediaOptim also processes everything locally.

Format Support

DaisyDisk doesn't deal with file formats—it just shows file sizes. MediaOptim supports video (H.264, HEVC), photos (JPEG, PNG, WebP, AVIF, HEIF), and audio (MP3, AAC, FLAC, WAV) compression.

When to Choose DaisyDisk

  • You want a clear visual overview of your entire disk
  • Your storage problem is from unexpected files (not just media)
  • You need to find large hidden folders or forgotten downloads
  • You're comfortable manually deciding what to delete
  • You want a gorgeous interface for disk analysis (it really is beautiful)

When to Choose MediaOptim

  • You already know your media files are the problem
  • You want to compress files instead of deleting them
  • You need actual media optimization (HEVC, WebP, AVIF)
  • You want batch processing to compress entire folders
  • You prefer a tool that takes action, not just shows information

Frequently Asked Questions

Can DaisyDisk compress files?
No. DaisyDisk is purely a disk analyzer and visualizer. It shows what's using your space with a beautiful sunburst chart, but the only action it offers is deletion. It cannot compress, re-encode, or optimize any files.
Should I get DaisyDisk or MediaOptim?
They solve different problems. If you don't know what's using your storage, DaisyDisk helps you find out. If you know it's media files (videos, photos) and want to shrink them, MediaOptim compresses them. Many users benefit from having both.
Is DaisyDisk worth buying?
Yes, DaisyDisk is excellent at what it does. At $9.99, it's one of the best values on the Mac App Store. Its visualization is genuinely the best way to understand your disk usage. Just know that it's a diagnostic tool—it tells you the problem but can't fix it.
Does MediaOptim have a disk visualizer like DaisyDisk?
MediaOptim has a Space Scanner that finds large media files on your drive, but it's not a full disk visualizer like DaisyDisk. MediaOptim focuses specifically on finding compressible media files, while DaisyDisk shows everything on your disk in a visual format.
