What photos and videos can I upload?
Photos: JPEG, PNG and WebP. Videos: MP4 and QuickTime (.MOV) in H.264, up to the size limit shown in the composer.
iPhone's default HEVC video and HEIC photo formats are not accepted yet. On an iPhone, Settings → Camera → Formats → Most Compatible records in H.264 and JPEG, which upload fine. If an upload fails, the message tells you why.
