Does Vauli work offline?

Yes. Every tool processes the video on your iPhone, so trimming, compressing and converting work without a connection. Your videos aren’t uploaded. Buying or restoring Vauli Pro needs a connection.

Can Vauli compress a video to a specific size?

Yes. In Compress Video, set File size to Target size and tap 10, 25, 50 or 100 MB, or enter any size from 5 to 2,000 MB. The result is checked after export.

Editing and previews are free, and your first 3 exports are free. After that, Vauli Pro unlocks unlimited exports.

Which videos can Vauli open?

MP4 and MOV videos from Photos or Files, up to two hours and 10 GB. You can also send videos to Vauli from another app with “Save to Vauli” in the share sheet.

Does Clean Audio use AI?

No. Clean Audio is a filter that reduces low rumble and quiet background noise in speech, with Natural, Balanced and Strong settings. It can’t separate overlapping voices.

Can I make a GIF from a video?

Yes. Video to GIF makes a GIF of up to 15 seconds, 240, 480 or 720 pixels wide, at 5, 10, 15 or 20 frames per second.

Trim, resize and compress, offline.

Vauli is a set of 20 video tools for iPhone, from Trim & Cut to Metadata Cleaner. The editing and exporting happen on your iPhone, with no upload.

3 free exports, then Vauli Pro. Editing and previews are always free.

Aim for a size, then check it.

Compress Video can aim for a file size: tap 10, 25, 50 or 100 MB, or enter any size from 5 to 2,000 MB. The result is checked after export.

Quality: High · Balanced · Small. Preview: up to 5 seconds before you export.

27.6 MB to 12.6 MB

Saved 15.0 MB · 54.4% smaller. Coastal-Sailing.mp4 · 1920 × 1080 · 0:12. Read off the capture above (Balanced quality). One 12-second clip, not a benchmark: results depend on the video.

Target size, in detail

Vauli Compress Video with File size set to Target size: quick sizes 10, 25, 50 and 100 MB, Target size 13 MB, and the notes “Aim for this size. The result is checked after export.” and “An already efficient video may not get smaller.”

Your videos stay on your iPhone

“Your media stays on your device.” Vauli Settings

Every tool runs on the iPhone, using Apple’s AVFoundation and Core Image.

Choose videos from Photos (up to 20 at once) or Files. Vauli doesn’t ask to read your photo library; it only asks to add exports to it.

“Save to Vauli” takes up to 20 videos from another app.

Exported files are written with their metadata cleared.

Purchases go through Apple and RevenueCat. The app also collects usage and diagnostic data (PostHog), not your videos.

Limits worth knowing

Videos up to two hours and 10 GB. Your iPhone needs the video’s size plus 50 MB free.
GIFs up to 15 seconds. Merges up to 20 clips.
Clean Audio is a simple filter: it cuts low rumble and quiet background noise in speech. It is not AI noise removal, and it can’t separate overlapping voices.
No captions, stabilization, upscaling or object tracking. Blur & Pixelate covers one fixed area for the whole video.
Mute Video keeps the original picture. Every other tool re-encodes it.
iPhone only, iOS 15 or later. No camera or screen recording, no accounts, no cloud.
