Single-purpose AI tools for the most common image-editing tasks. Each one is tuned for its task and runs in seconds.
Editing tools
Background Remover
Drop a photo and the background disappears in seconds. Free, unlimited, and the AI runs entirely in your browser, your photo never leaves your device. Output is a real transparent PNG ready to layer anywhere. For products, fine hair detail or busy scenes, the Pro remover takes over.
Background Changer
Upload a photo, describe the new background you want in plain English, and renza replaces it. Studio backdrops, beach scenes, office settings, anything. The lighting on your subject adjusts to match the new environment automatically.
Image Upscaler
Upload any image and renza upscales it 2× or 4× using Topaz. Detail is reconstructed cleanly, faces stay intact, and the output is high enough resolution for print, large displays, or professional use.
Object Remover
Upload a photo, tell renza what to remove (a person, an object, a watermark, a logo), and the AI fills the empty space with what should naturally be there. No manual masking required.
Photo Restoration
Upload an old or damaged photo and renza restores it. Fixes scratches, tears, water damage, fading and blur. Faces stay recognisable, era stays authentic. Perfect for breathing life back into family photos.
Colorize Photo
Upload any black-and-white photo and renza adds color. Skin tones look natural, clothing reads period-appropriate, scenes feel alive. Perfect for old family photos, historical photography, or just exploring what a B&W shot would have looked like in color.
Photo Enhancer
Upload any photo and renza enhances it. Sharper detail, recovered clarity, reduced noise, better exposure. Powered by Topaz, which is the gold standard for AI photo enhancement.
Image Resizer
Drop an image, pick a width or height, and download the resized version. Runs entirely in your browser, your photo never leaves your device.
Image Converter
Pick your input file and the target format. Conversion happens locally, your image never leaves your browser. Download the converted file in seconds.
