PERSONAL FILES SHOULD STAY PERSONAL

On your device.
Out of anyone else’s hands.

Your browser does the work. Luma doesn’t upload your photos or videos for processing, and there’s no account to create. Website assets still need a connection; your media doesn’t leave with them.

THE SHORT ANSWERS

A few things
you might wonder.

Is everything really free?

Yes. There are no subscriptions, accounts, watermarks or daily usage quotas. Per-operation memory safeguards keep processing manageable. Future advertising may help fund the site, but no advertising is installed in this version.

Where do my files go?

Files are opened by your browser and processed on your device. We don’t send them to a processing server. Downloads go wherever your browser normally saves files. Closing the page releases its temporary media data.

Will it work on my phone?

Image tools are designed for current mobile browsers. Large images and batches can exceed a phone’s memory. Video support varies more widely; use a recent desktop browser and short clips for the best chance of success.

Are there limits on file sizes?

Yes. Image inputs are limited to 40 MiB and 24 megapixels each, with smaller batches recommended on mobile. Video has a 150 MiB, five-minute, 1080p safety boundary. These are practical device protections, not daily usage quotas.
