How it works
Tile boundaries use adjacent floor-rounded coordinates. Together, all tiles cover the exact original width and height with no gaps or overlapping edge pixels.
Output and metadata
Output keeps the original pixel dimensions. Canvas re-encoding usually omits source metadata such as EXIF or IPTC fields; do not rely on metadata preservation. JPEG output is lossy, while PNG is used when the source needs transparency.
Practical limits
Files are limited to 25 MB, 40 megapixels, and 12,000 pixels per side. These safeguards reduce browser memory failures. Replace or reset an image to release the prior decoded buffer.
