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. |
| Privacy（判断項目） | Byteflow のローカル手順：Use the プライバシーと信頼センター, tool 信頼ラベル, and sample inputs to verify whether sensitive data stays in the browser. | 別の選択肢：Review each alternative's runtime behavior, storage policy, analytics, and deployment owner before using production data. | 実務メモ：No comparison page should be treated as permission to paste secrets without verification. |
| Local execution（判断項目） | Byteflow のローカル手順：Prefer ブラウザーローカルツール for parsing, formatting, encoding, hashing, redaction, and snippet generation when a network call is unnecessary. | 別の選択肢：Some hosted tools may proxy, store, or execute work on a server even when the UI feels instant. | 実務メモ：Use DevTools Network with sample data when the processing boundary matters. |
| Offline use（判断項目） | Byteflow のローカル手順：Use installable PWA flows and cached tool shells for workflows that should remain available without a live connection. | 別の選択肢：Many single-purpose online tools require a fresh network request for the page, scripts, or processing endpoint. | 実務メモ：Offline availability still depends on the route and assets having been cached first. |
| オープンソース（判断項目） | Byteflow のローカル手順：Review the public repository, issues, and implementation when a workflow needs inspectable behavior. | 別の選択肢：Closed or opaque tools require more vendor trust because runtime and storage behavior may not be independently reviewable. | 実務メモ：オープンソース does not replace verification, but it makes claims easier to audit. |
| Workflow composition（判断項目） | Byteflow のローカル手順：Combine focused tools, related links, and パイプラインビルダー when a task needs repeatable multi-step handling. | 別の選択肢：Recipe workbenches or specialized sites may be faster when their composition model already matches the task. | 実務メモ：Choose the model your team can document and repeat with the least ambiguity. |
| Platform coverage（判断項目） | Byteflow のローカル手順：Run the web app in modern desktop and mobile browsers, with installable app behavior where supported. | 別の選択肢：Native apps, extensions, CLI tools, and hosted sites can cover different device or automation needs. | 実務メモ：Check the target platform before standardizing a team workflow. |
| Pricing（判断項目） | Byteflow のローカル手順：Use the public site and source without an account for the comparison workflows described here. | 別の選択肢：Some alternatives may add paid tiers, account requirements, usage limits, or hosted-team features. | 実務メモ：Verify current pricing and limits before making a procurement decision. |
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.
