Why convert WebP to JPEG
Compatibility, almost always. JPEG is the most universally accepted image format there is: every browser, every editor, every upload form, every print pipeline. WebP is better on the web and worse nearly everywhere else.
The conversion costs you file size — a JPEG of the same image is typically 25–35% larger than the WebP — and a small amount of quality, because the image is being re-encoded.
What you lose besides size
- Transparency. If the WebP has an alpha channel, JPEG cannot store it and the transparent areas will be filled with a solid colour.
- Animation, if the WebP was an animated sequence — JPEG has no equivalent.
- The quality you already spent. Re-encoding a lossy image always loses a little more.
The better alternative when you can use it
If the destination accepts PNG and the image is a screenshot or a graphic, PNG will be both more compatible and lossless — though larger than the WebP. If the destination is a photograph and only accepts JPEG, this conversion is exactly right.
常見問題
為什麼要把 WebP 轉成 JPG?
JPG 到處都適用 — 電子郵件用戶端、印表機和舊版軟體。WebP 在較舊的裝置上不一定能正確顯示。
我會損失品質嗎?
轉換為 JPG 是有損的,但在品質 80–90 時,差異對肉眼幾乎不可見。
這是私密的嗎?
是的 — 轉換完全在你的瀏覽器中進行。
