AVIF 很有效率，但並非到處都有支援。將 AVIF 轉換為 JPG，以與舊版瀏覽器、電子郵件用戶端和照片軟體普遍相容。
所有處理都在本地進行 — 不會上傳任何內容。

The usual reason: something will not open AVIF
AVIF is the most efficient format here and the least universally supported. Plenty of software still cannot read it — older photo editors, document tools, some print workflows and a long tail of upload forms. Converting to JPEG is the reliable way out.
Expect the result to be substantially larger than the AVIF, often 1.5 to 2.5 times the size, because JPEG is simply a less efficient encoder.
What does not survive
AVIF can carry transparency, wide colour gamuts and high dynamic range. JPEG carries none of those. Transparency becomes a solid fill, wide-gamut colour is clipped to sRGB, and HDR is tone-mapped down. If any of those matter, convert to PNG for transparency or accept that the JPEG is an SDR reduction.
Check the result before you rely on it
Because AVIF files are often the product of an already-optimised pipeline, the JPEG you get back may look softer than you expect — you are encoding a second time. Compare the two side by side at 100% before shipping the JPEG anywhere that matters.
常見問題
為什麼 AVIF 打不開？
AVIF 是較新的格式。舊版瀏覽器、應用程式和作業系統可能無法解碼它。
JPG 是最好的輸出嗎？
就相容性而言，是的 — JPG 幾乎可以在每台裝置和程式中開啟。
這會上傳我的圖片嗎？
不會 — 轉換完全在你的瀏覽器中進行。
