Important limitations
A PNG can be considerably larger than a compressed photograph. Transparency is only preserved when present in input.
Image decoding and encoding support vary by browser. Files are limited to 20 MB, 30 million decoded pixels and a 16,384 pixel maximum on either side. Very low-memory devices may fail before these limits. Canvas export generally drops EXIF and other source metadata; it should not be treated as a formally verified secure-metadata-removal tool.
See the supported formats guide or other image tools.
