About Lumina Studio
Free • Private • Browser-based image tools
What is Lumina Studio?
Lumina Studio is a free, privacy-first suite of image tools that runs entirely in your browser. Create AI-generated images, perfectly fit photos for social media, resize, and compress images to WebP or JPEG — without uploading your files to any server or creating an account.
Our Tools
-
✨
AI Image Studio — Generate high-quality images using Flux and SDXL models via a public rendering endpoint. No API keys required.
-
📱
Social Media Fitter — Fit any image into Instagram, TikTok, YouTube, Twitter/X presets with aesthetic blurred or solid backgrounds.
-
🗜
Compressor & WebP Converter — Convert and compress images locally with adjustable quality. Everything stays on your device.
-
📏
Image Resizer — Resize with aspect-ratio lock for clean, distortion-free results.
Privacy First
Image processing (resize, compress, social fit) happens 100% on your device using the browser’s Canvas API. Your photos never leave your computer. Only the optional AI generation feature sends a text prompt to a third-party rendering service.
Free Forever
Lumina Studio is free to use. We support the project with optional, non-intrusive advertising and partner offers so you can keep creating without paywalls or subscriptions.
