AI Video Compressor
A 4K export won't fit through a 25MB email cap, chews through client upload portals, and takes an hour to send anywhere. Crushing the bitrate fixes the size and ruins the video. Eliro's AI compressor reads what's in each frame — faces, on-screen text, motion — and spends the data where viewers will notice, cutting file size by up to 90% without the smeared, blocky look of dumb compression.
- Up to 90% Smaller Files
- Faces & Text Stay Sharp
- Hit Any Target Size, Like "Under 25MB"

Compression That Knows What It's Looking At
The difference between content-aware AI and a bitrate slider
Data Goes Where Eyes Go
Faces, captions, and moving subjects get the bits; flat walls and static backgrounds give them up. That's how 90% size cuts can survive a side-by-side comparison.
Name a Target Size
Type "under 25MB" for an email attachment or "under 8MB" for an embed, and the AI finds the settings that hit the number with the most quality the budget allows.
Beat Platform Re-Compression
YouTube, Instagram, and TikTok re-encode everything you upload. Platform presets deliver files inside each platform's sweet spot, so their second compression pass has less to destroy.
Shrink an Archive, Not Just a File
Queue hundreds of videos with one settings profile and reclaim entire drives. Content libraries that ate terabytes come back at a fraction of the size.
Modern Codecs, Universal Playback
Output in H.264 for compatibility everywhere, or H.265, VP9, and AV1 when you want maximum efficiency. Input can be MP4, MOV, AVI, MKV, WebM, and more.
Audio Left Alone by Default
Audio is a sliver of total file size, so it keeps its quality unless you choose otherwise. No mysteriously muffled voiceovers after compression.
Shrink a File Without Wrecking It
Upload the Heavy File
Drop in the oversized export — 4K footage, screen recordings, drone clips. MP4, MOV, AVI, WebM, and more are accepted.
Set the Goal
Pick a target size, a quality level, or a platform preset. The AI analyzes the content and allocates data frame by frame to hit it.
Compare and Download
Check the before/after preview, confirm the quality holds, and download a file that's a fraction of the original size.
Where Smart Compression Pays Off
Files That Fit Where They Need to Go
Email caps at 25MB. Discord, Slack, and client portals all have their own ceilings. Course platforms meter your storage. Instead of guessing at export settings until something fits, name the limit and let the AI hit it with the best possible picture.
Uploads That Don't Eat Your Day
A 2GB export on hotel Wi-Fi is an afternoon gone. Compressing to a tenth of the size before upload means faster publishing, fewer failed transfers, and — because the file sits inside the platform's preferred range — often better quality after the platform's own re-encode.
Before You Compress
The smallest file is the one with nothing wasted in it. These trim the fat first.
Remove Filler Words
Cut the "ums" and pauses first — shorter video, smaller file, before compression even starts.
AI B-Roll Generation
Replace bloated stock clips with generated B-roll sized for your final output.
Publish & Schedule
Send the compressed file straight to YouTube, TikTok, or Instagram without re-uploading.
AI Video Editor
Make the final cut and compress the export in one place instead of round-tripping files.
