How we keep content accurate

フォーマット仕様は元の規格と照合してチェックされます (W3C PNG, ISO/IEC 10918 (JPEG), IETF RFC 1951 (DEFLATE), and similar). Time zone data is sourced from the IANA タイムゾーンデータベース. Our editorial team verifies every tool page before publication and re-reviews after meaningful changes; review attribution is maintained in the page metadata and structured data.
