Image tools that do not need to see your images.
Most online image tools work by uploading your files to a server somewhere. Metamorfiles works by not doing that.
Why we built it
Photographers handle client work. Businesses handle contracts and ID scans. Most people just have photos they would rather not hand to a stranger. All of them still need a smaller file.
Modern browsers can decode and re-encode images on their own, so the upload step is not a technical requirement. It is a habit. We built the free tools around the Canvas API so that habit could be dropped: you get the same result, faster, and your files never leave the tab.
Studio is the paid half. It is for people who need many finished images from one design: a card for every product, a post for every A/B hook, a banner for every platform size. It runs on your own machine, inside the AI agent you already use, so there is no account, no subscription and nothing of yours on our servers.
What you can hold us to
- Your files stay yours
- The free tools never upload anything. Studio runs on your computer, so your brand kit, templates and renders never reach us.
- No waiting
- There is no queue and no round trip. A file is done in the time it takes your own machine to redraw it.
- Free means free
- Compression and conversion have no limits, no watermark and no account. They cost us nothing to run, so they cost you nothing.
- Real codecs, no tricks
- We use the browser's own image encoders. The output is a standard PNG, JPEG or WebP that any app can open.
What happens to a file
Four steps, all of them on your device.
- 1The image is read into your browser's memory.
- 2The Canvas API redraws it at the size and quality you set.
- 3The browser encodes a new file in the format you chose.
- 4You download it. No server was involved at any point.
