How to Batch Compress Multiple Videos on iPhone
Compressing videos one at a time is tedious. Batch mode lets you select many clips, apply a single configuration, and export them all in one run — ideal for clearing space or prepping a folder of clips.
Quick answer: Open Kompresso, select multiple videos, choose one preset or advanced configuration for the whole set, and tap Compress. Every clip is processed and exported together.
When to batch compress
- Freeing up storage across dozens of large clips at once.
- Prepping a set of videos for upload or a client at a consistent size.
- Converting a whole folder from HEVC to H.264 MP4 for compatibility.
- Standardizing resolution and format across everything you shot on a trip.

Batch tips for the best results
Group similar clips — batching all your 4K clips with one setting, and your 1080p clips with another, gives more predictable results than mixing everything. For a storage clear-out, pair batch mode with Delete Original; see how to free up iPhone storage by compressing videos.
Tip: Batch mode uses one configuration for the set. If a few clips need special handling, do those separately after the main batch.
