Why Convert MPG to MP4?

About MPG Format

MPG 是 MPEG-1 與 MPEG-2 編碼影片檔案常見的副檔名。這類檔案與較舊的媒體播放器和 DVD 系統廣泛相容,適合處理舊有影片內容與光碟媒體。

Benefits of MP4 Format

MP4(MPEG-4 Part 14)是當今使用最廣泛的影片容器格式,透過 H.264 或 H.265 編碼在維持高畫質的同時實現出色的壓縮率,幾乎所有裝置、瀏覽器與平台都支援這種格式。

Having dealt with trying to install ffmpeg and ImageMagick, and their dependencies, and plugins for the file types I needed, the time I spent cost me more than that.

👋 向隱私疑慮與不支援的格式說再見。

使用安全的 本機執行 這款檔案轉換應用程式致力於支援幾乎所有檔案格式。如果您發現有格式尚未支援, 提出新增申請. 我是 公開開發.

  • MP4 轉 MOV、MKV 轉 MP4、AVI 轉 MP4、WebM 轉 MP4、影片轉 GIF。可調整畫質、解析度與編碼設定。

  • 別讓電子郵件與網站的檔案大小限制擋住您。把圖片和影片壓縮到原本的一小部分,在不明顯損失畫質的情況下縮小檔案大小。

  • 批次轉換可以節省大量時間。把多個圖片、影片或文件一起拖進來,一次全部轉換完成,特別適合處理整個資料夾或相片集。

  • HEIC 轉 JPG、RAW 轉 JPG、WebP 轉 PNG、PNG 轉 ICO。可調整畫質、調整圖片尺寸並壓縮,也能處理 PSD 和相機 RAW 等專業格式。

  • 精準裁切圖片與影片,聚焦在真正重要的部分。移除不需要的區域、調整長寬比,打造完美的縮圖,支援所有常見的圖片與影片格式。

  • MP4 轉 MP3、WAV 轉 MP3、FLAC 轉 MP3、M4A 轉 MP3。可從幾乎任何影片格式擷取音訊,並設定位元率、音質、壓縮等選項。

  • MD 轉 PDF、DOCX 轉 HTML、EPUB 轉 PDF、HTML 轉 PDF。以多種格式建立電子書、文件與簡報。

  • 大幅縮小 PDF 檔案。選擇無損壓縮以維持品質,或選擇有損壓縮讓檔案更小。很適合用電子郵件寄送或上傳。

  • 把商標、草稿、圖示與平面美術作品轉換成真正可縮放的 SVG 路徑。這是真正的向量化,而不是把點陣圖包裝成 SVG 檔案,所以放大縮小都能維持清晰銳利。

    查看圖片向量化
  • 將 EML、MSG 等電子郵件檔案轉換為 HTML、PDF、圖片與文字。

  • 支援超過 5000 種轉換,並提供進階設定選項。所有處理都在您的裝置上完成,檔案不會離開您的電腦。
