Comparison
Compresto vs Keka
Keka excels at creating ZIP, 7Z, and RAR archives for file sharing. Compresto compresses the actual media inside those files — making videos smaller, images lighter, and PDFs leaner before you even archive them.

Frequently Asked Questions
- What is the difference between Compresto and Keka?
- Compresto reduces the size of media files (video, images, PDFs) by re-encoding or optimizing their content. Keka creates archive containers (ZIP, 7Z) that bundle files together. They are complementary tools that serve different compression needs.
- Can Keka compress video files?
- Keka can include videos in archives but does not re-encode or reduce the actual video file size. Compresto reduces the video file itself using hardware-accelerated encoding.
- Should I use Compresto or Keka to share large files?
- Use Compresto to make files smaller first, then use whatever sharing method works (email, cloud, or Keka archive). Compresto is better if the recipient needs the files in their original format without extraction.
- Can I use Compresto and Keka together?
- Yes — this is actually a great workflow. Compress media with Compresto to reduce size, then use Keka to bundle multiple files into an archive if needed.
- Is Keka free?
- Keka is free on their website or $2.99 on the Mac App Store. Compresto has a free tier and a $19.99 one-time purchase.
