Lossless baseline for further work.
TIF preserves every detail of the source JPEG, which prevents additional quality loss during subsequent edits or re-encoding. The original JPEG compression cannot be undone, but no new artifacts will be introduced.
為什麼要轉換
01
TIF preserves every detail of the source JPEG, which prevents additional quality loss during subsequent edits or re-encoding. The original JPEG compression cannot be undone, but no new artifacts will be introduced.
02
TIF is accepted by a wider range of image viewers, editors, and content systems than JPEG. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
TIF is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.

是的。LocalConvert 完全免費,無需註冊,也沒有每檔案或每日的限制。
不會。JPEG 到 TIF 的轉換完全在你的瀏覽器內透過 WebAssembly 完成 —— 你的檔案永遠不會離開你的裝置。
沒有固定上限 —— 實際限制取決於你裝置的可用記憶體。在低記憶體裝置上,非常大的檔案可能耗時較久或失敗。
可以 —— 頁面載入後,JPEG 到 TIF 的轉換無需網路連線即可運作。重新開啟頁面一次即可快取。
LocalConvert 使用業界標準工具(FFmpeg、ImageMagick、Pandoc)—— 品質與專業人員在命令列中使用的相當。有損格式每次重新編碼仍會損失一些品質。
