將圖片轉換為 PDF，對於歸檔收據、製作相簿、將截圖以文件形式傳送，或將商品圖片合併為單一交付物都很有用。
何時將圖片轉換為 PDF
- 歸檔收據與文件。 將掃描或拍攝的收據合併為一個 PDF 以便報帳。
- 相簿與作品集。 將相關圖片歸為單一檔案以便 email 或分享。
- 客戶交付物。 將商品圖片、情緒板或截圖以單一 PDF 傳送，而非個別檔案。
- 印刷準備。 為偏好 PDF 輸入的印刷服務準備圖片。
可靠的流程
- 若圖片比所需大很多，先使用 圖片調整尺寸工具。
- 開啟 圖片轉 PDF 轉換器。
- 上傳你的 JPG、PNG 或 WebP 圖片。
- 按你想要的順序排列。
- 選擇頁面尺寸與配置設定。
- 下載合併後的 PDF。
PDF 轉換前準備圖片
清晰且尺寸合宜的圖片能產出更好的 PDF。開始前幾項檢查：
- 調整過大圖片的尺寸。 文件中使用 4000px 的照片會讓 PDF 變得臃腫。使用 圖片調整尺寸工具 將尺寸降到實用大小。
- 壓縮過重的檔案。 將大檔案透過 圖片壓縮工具 處理後，再加入 PDF。
- 轉換不相容的格式。 若部分圖片為 PDF 工具不支援的格式，請先用 圖片轉換工具 切換為 JPG 或 PNG。
何時改用其他方式
PDF 轉換並不總是最佳選擇。若收件者需要可編輯的圖片，請改以 ZIP 分享原始檔案。若輸出是給相簿印刷服務使用，請確認該服務偏好個別圖片而非合併的 PDF。
