Upload a photo and stamp a festival theme — National Day, Christmas, Spring Festival, Mid-Autumn — drawn purely with Canvas.
Pick a photo, choose a theme (National Day stamps 5 gold stars like the Chinese flag; Christmas adds snowflakes around the border; Spring Festival adds lanterns at corners and a 福 character; Mid-Autumn adds a moon glow in the corner). Choose circle or square crop, border width and decoration density. All decorations are drawn by Canvas — no external images. Output is a 512×512 PNG, ready for social profile pictures. Your image never leaves the browser.
