比較：SVG オプティマイザー vs SVG コンバーター
判断フレーム：Choose between optimizing an SVG source file and converting SVG artwork into PNG or other delivery-friendly outputs.
利用場面：Use this comparison when preparing icons, diagrams, social images, or design assets for production delivery.
判断材料
| 項目 | Byteflow | もう一つの選択肢 | 実務上の注意 |
|---|---|---|---|
| Output format（判断項目） | Byteflow のローカル手順：SVG オプティマイザー returns a smaller sanitized SVG for web delivery and source control. | 別の選択肢：SVG conversion creates PNG or transformed vector output for platforms that need a different format. | 実務メモ：Keep SVG when scalability and CSS styling matter. |
| Security boundary（判断項目） | Byteflow のローカル手順：Optimization should remove scripts, event handlers, external references, and editor metadata. | 別の選択肢：Conversion can neutralize some SVG risks by rasterizing, but source review is still important. | 実務メモ：Do not assume every SVG from a third party is safe. |
| Quality tradeoff（判断項目） | Byteflow のローカル手順：Optimized SVG remains sharp at any size and can be inspected as text. | 別の選択肢：Raster conversion fixes dimensions and may be easier for emails, social previews, or legacy tools. | 実務メモ：Pick the format your target renderer supports reliably. |
実務判断：Use optimization for web SVG delivery
実務判断：Choose optimization when the final asset should remain scalable, text-readable, cacheable, and easy to review in version control.
実務判断：Use conversion for fixed targets
実務判断：Choose conversion when the destination requires PNG, has inconsistent SVG support, or needs a fixed-size preview image.

信頼性チェック
プライバシー境界：Treat uploaded SVGs as untrusted input. Sanitization and conversion should happen locally and should not preserve hidden metadata by default.
プライバシーと信頼センターよくある質問
質問：Does optimizing SVG change the visual result?
回答：It should preserve the intended appearance while removing unnecessary or unsafe markup. Always preview the result before shipping.
質問：Is converting SVG to PNG safer?
回答：Rasterizing can remove active SVG behavior from the delivered asset, but you should still treat the original SVG as untrusted input.
