Side Preview

在 Chrome 側欄預覽 PDF、圖片、GIF、影片與 Excel/CSV，檔案只在本機解析、不上傳。

繁體中文 在網頁上看到 PDF、Excel 或圖片連結，不用再下載、開檔、切視窗。Side Preview 讓檔案直接在 Chrome 右側的側欄打開，原本的網頁照樣留在左邊；想要大畫面，也可以改成在新分頁整頁預覽。 【怎麼開】 ・滑鼠停在檔案連結或網頁圖片上，點浮出的小預覽圖示（沒有副檔名的後台下載連結，只要標題或文字寫著 PDF、Excel 等也認得出來；沒有網址的附件按鈕，只要文字是檔名也認得） ・在連結或圖片上按右鍵，選「在側欄預覽」（新分頁模式下為「在新分頁預覽」） ・把電腦裡的檔案拖進側欄 ・開啟「下載改為預覽」後，網頁要下載的檔案會直接打開預覽 【側欄或新分頁，任你選】 在設定開啟「用新分頁開啟預覽」，從網頁預覽的檔案會改在緊鄰的新分頁整頁顯示，不開側欄；每個檔案一個分頁，分頁標題就是檔名。檔案一樣只在你的電腦上解析，需要登入的檔案也照樣看得到。 【支援格式】 ・PDF：連續捲動、跳頁、縮放、可選取文字，數百頁也流暢 ・圖片：PNG、JPG、WebP、SVG、GIF（會動），可縮放、平移、旋轉 ・影片：MP4（H.264）、WebM ・試算表：XLSX、XLS、CSV，可切換工作表、點儲存格看完整內容，十萬列也不卡 【需要登入的檔案也能看】 預覽時會使用你在該網站的登入狀態抓檔。若管理後台以登入通行證保護檔案，可以對該網站啟用「後台模式」：必須逐站同意，通行證只暫存在記憶體，關閉瀏覽器即清除，也可隨時在設定移除。 【隱私】 所有檔案都在你的電腦上解析，不會上傳到任何伺服器。預覽時處理的檔案內容、檔案網址與後台模式的登入通行證，都只在你的電腦上處理，不傳送給開發者或任何第三方；套件沒有自己的伺服器，也不含任何分析、廣告或追蹤程式。 English See a PDF, spreadsheet or image link on a web page? Skip the download-open-switch routine. Side Preview opens the file right in Chrome's side panel while the page stays on the left — or, if you prefer a bigger view, in a full-page new tab. HOW TO OPEN • Hover a file link or an image on the page and click the small preview icon (back-office download links without a file extension are recognized too when their title or text says PDF, Excel and so on; attachment buttons with no link are recognized as long as their text is a file name) • Right-click a link or image and choose "Preview in side panel" ("Preview in new tab" in new-tab mode) • Drag a file from your computer into the side panel • Turn on "Preview downloads" and files a page tries to download open as a preview instead SIDE PANEL OR NEW TAB Turn on "Open previews in a new tab" in Settings and files you preview from a page open in a full-page tab right next to it instead of the side panel — one tab per file, titled with the file name. Files are still parsed only on your computer, and files behind a login still work. SUPPORTED FORMATS • PDF: continuous scrolling, page jump, zoom, selectable text — smooth even with hundreds of pages • Images: PNG, JPG, WebP, SVG and animated GIF, with zoom, pan and rotate • Video: MP4 (H.264) and WebM • Spreadsheets: XLSX, XLS and CSV, with sheet switching and full cell values — 100,000 rows stay responsive FILES BEHIND A LOGIN Previews use your existing login on that site. For admin back-offices that protect files with login credentials, you can enable "back-office mode" per site: it requires your explicit consent for each site, credentials are kept in memory only and cleared when you close the browser, and you can remove a site at any time in Settings. PRIVACY All files are parsed on your computer and never uploaded to any server. The file content, file URLs and back-office login credentials handled for previews are processed only on your computer and are never sent to the developer or any third party; the extension has no server of its own and contains no analytics, advertising or tracking code.
