Limitations
- PNG, JPEG and static WebP only. 20 MiB and 24 megapixels per input, 16,384 pixels per side; output at most 24 megapixels and 64 MiB. Multi-image input totals at most 100 MiB. Processing runs in a cancellable worker with a 120-second deadline. Rendered PNG outputs use stored pixel orientation and browser-decoded colors, with no source EXIF/XMP/text copied.
- One line of text, 1–500 characters, uses browser sans-serif; font appearance can vary by system. Coordinates are the top-left corner. Text or watermark image must fit. An image watermark keeps its aspect ratio.
