How to use

Choose a PNG, JPEG or WebP image up to 20 MB and 32 megapixels. Set a maximum output side of 64–4096 pixels without enlarging the image. Watermarks support position, opacity, angle and repetition; captions support up to 200 characters each. Nine-grid exports nine numbered PNGs in a ZIP, with full-image fitting or centered square cropping, and requires at least 3 by 3 source pixels. ASCII uses 20–200 columns and at most 200 rows. Output is limited to 50 MB.
