ZIP Creator & Extractor — what it does
Create a ZIP archive from files you select, or open an existing ZIP to inspect its contents and extract them — all inside the browser, with nothing uploaded. It covers both directions of the everyday archive task on a machine where you may not have an archiving tool installed.
When this tool helps
- Bundling several files into one archive to send as a single attachment.
- Checking what is inside a ZIP before extracting it onto your disk.
- Extracting files on a computer with no archiving software available.
How to use it
- To create: choose the files and build the ZIP.
- To inspect: load a ZIP file and read its contents list.
- Extract all files when you are ready.
- Download the archive or the extracted files.
Accuracy, limits, and good practice
- Inspecting before extracting is a genuine safety habit — it shows what an unfamiliar archive would write to your disk before it writes anything.
- ZIP compresses text and documents well and barely touches media files, since JPEG, MP4 and MP3 are already compressed.
- Encrypted archives cannot be opened here; a password-protected ZIP needs dedicated archiving software.
- Archive a folder's contents with meaningful filenames: a ZIP of files named image1 through image40 is only marginally better than sending them loose.
Frequently asked questions
Are my files uploaded?
No. Archives are created and read in your browser, so the contents never leave the machine.
Can it open RAR or 7z files?
No, only ZIP. Other archive formats need their own tools.
How big an archive can it handle?
Memory is the limit, since the whole archive is processed in the tab. Very large archives are better handled by desktop software.
Does zipping protect the files?
No. A plain ZIP offers no encryption, so treat its contents as readable by anyone who receives it.

ZIP 建立與解壓工具能做什麼
從你選取的檔案建立 ZIP，或開啟既有 ZIP 檢視內容並解壓縮——全部在瀏覽器中完成，不會上傳任何東西。在沒有安裝壓縮軟體的電腦上，它把日常封存工作的兩個方向都包了。
什麼時候用得上
- 把多個檔案打包成一個封存檔，以單一附件寄出。
- 在解壓到硬碟之前，先看看 ZIP 裡面有什麼。
- 在沒有壓縮軟體的電腦上解開檔案。
使用步驟
- 建立：選擇檔案並產生 ZIP。
- 檢視：載入 ZIP 檔並閱讀內容清單。
- 確認無誤後解壓縮全部檔案。
- 下載封存檔或解出的檔案。
精確度、限制與實務建議
- 先檢視再解壓是實在的安全習慣——它讓你在陌生封存檔寫入硬碟之前，先看到它會寫入什麼。
- ZIP 對文字與文件壓縮效果好，對影音幾乎沒用，因為 JPEG、MP4 與 MP3 本身早已壓縮過。
- 加密封存檔在此無法開啟；有密碼的 ZIP 需要專門的壓縮軟體。
- 封存時請確保檔名有意義：一包從 image1 到 image40 的 ZIP，只比散裝寄送好一點點。
常見問題
檔案會被上傳嗎？
不會。封存檔在瀏覽器中建立與讀取，內容不會離開這台電腦。
可以開 RAR 或 7z 嗎？
不行，只支援 ZIP。其他封存格式需要各自的工具。
可以處理多大的封存檔？
上限在記憶體，因為整個封存檔都在分頁中處理。超大檔案建議交給桌面軟體。
壓縮成 ZIP 有保護作用嗎？
沒有。一般 ZIP 不提供加密，請把內容視為任何收到它的人都讀得到。
