02Why Cosven
Free, offline, on-device AI — your photos stay private
Not another website that uploads your pictures. Cosven runs on your phone and computer. No account, and we never receive your photos.
On-device AI
Run powerful AI directly on your phone or computer. Fast, private and secure — the photo never goes to a website.
Works without the internet
After the AI downloads once, background removal works in airplane mode. You only need internet the first time.
Free — no account, no ads
No subscription, no tracking, no pay-per-photo fees. Built on free public AI with safely checked downloads.
Your photos stay with you
Sites like Remove.bg upload your photo to their servers. Cosven edits on your device, so we never receive it.
Many photos at once on PC
Remove backgrounds from a whole folder and download one ZIP file — no waiting in an online queue.
Clear about what works today
Background remove works on phone and PC. Upscale on PC. Other tools are labeled “coming soon” — no surprises.
03How it works
On your phone. On your computer.
Not on someone else’s website.
You only need internet once to download the AI. After that, background removal works without Wi‑Fi — like editing a file that stays on your phone.

05Why it stays private
Your photos stay on your phone or computer
Online AI tools send your picture to their website. Cosven is different — the editing happens on your device, like using a photo app that never uploads your library.
0
No uploads, no analytics on your images, no account tying them to you.
On your phone
The AI runs directly on your Android phone. Your photos are not sent to us or any website.
On your computer
On a PC or Mac, Cosven runs on your machine — not on computers in a data center somewhere else.
Internet only the first time
You need internet once to download the AI. After that, airplane mode works for background removal.
Honest labels in the app
What works today is marked “live.” What is not ready yet is marked “coming soon.” Same as this website.
Transparent AI
We use well-known free AI (MODNet, Real-ESRGAN, and others) with safely verified downloads. See the models page.
