PicMaestro is an online studio that brings five AI image tools together under one account and credit balance: an AI Image Upscaler, AI Photo Enhancer, Old Photo Restoration, AI Image Extender, and a text-guided AI Image Editor. Upscaling enlarges photos at 2x, 3x, 4x, or 8x; enhancement refines lighting, color, and clarity; restoration repairs scratches and creases on old prints; the extender generates new scenery beyond the original frame; and the editor changes a selected area or the whole image from a written description. The workflow is the same across all five: choose a tool, upload a photo, adjust the settings, review the credit cost, and compare the result with the original before downloading. Reference examples can be explored without signing in, but processing your own photo requires an account and credits. One-time credit packs start at $4.90 for 500 credits, and every tool draws from the same balance. PicMaestro suits photographers, sellers, and creators who want upscaling, restoration, and editing in one place instead of juggling separate apps.
