Technical Specifications & How It Works
Social media algorithms frequently crop images awkwardly if they do not match recommended aspect ratios.
The blurred background fill technique preserves 100% of your original photo while elegantly filling negative margins.
100% Client-Side Privacy: Your images never leave your computer or phone. Processing runs completely in local browser memory via WebAssembly and Canvas APIs. No file data, filenames, or metadata are ever transmitted.
