ZIP compress / extract
Browse the archive tree · download a single file or repack · many files into one ZIP in a click
解包 ZIP（≤2GB 解压后总大小）
点击选择或拖拽一个 .zip 到此处
仅未加密 ZIP；条目 ≤2 万、单文件 ≤500MB、解压总大小 ≤2GB；危险条目名（../、绝对路径、盘符）会被逐条拒绝
压缩成 ZIP（多文件 / 文件夹）
点击选择（可多选）或拖拽多个文件 / 整个文件夹到此处
文件夹会保留内部目录结构；输出文件名默认取第一层文件夹名
解包一个陌生 ZIP 前，先做这几道检查
文件名先过"zip-slip"守卫。历史上大量解压工具被"路径穿越"条目坑过：条目名里写 ../../etc/passwd 或 C:\Windows 这种，解到磁盘上就能写出压缩包目录之外。本页对每一条路径做校验——绝对路径、盘符、.. 上级引用一律拒绝，并在列表里标出原因；即使你只是浏览而不落盘，这道检查也不省。
再防 zip 炸弹。"1KB 的 ZIP 解压出 100GB"是经典恶作剧。本页设三道闸：条目数 ≤2 万、单文件 ≤500MB、解压总大小 ≤2GB——任何一道超了立刻停止并告诉你是哪条触发的，不会让你的浏览器卡死。
中文乱码多半是 GBK。ZIP 规范默认文件名是 ASCII；Windows 上一部分压缩工具把中文名存成 GBK 字节且不打 UTF-8 标志位，于是别的工具按 UTF-8 读就变成乱码。本页自动识别（看标志位 + 试解码是否有中文特征），也可手动强制切换。
FAQ
No. Browsers cannot decode those two natively, and open-source decoders for them are either patent-encumbered or incomplete, so this page sticks to the open ZIP format; for RAR and 7z please use a desktop tool.
No. This page only compresses and extracts unencrypted ZIP and never asks for any password - and as a reminder the other way round: be wary of any online unzip page that demands a password from you.
Some compression tools on Windows save Chinese names in GBK without setting the UTF-8 flag. This page detects that automatically and decodes as GBK (you can also switch manually between auto / UTF-8 / GBK); if it is still garbled, the packing side used inconsistent encodings and the archive needs re-packing.
Yes. Every entry name is checked one by one: absolute paths, drive letters and parent-directory references (../) are all refused (zip-slip defense); caps are 20,000 entries, 500MB per file and 2GB unpacked total (zip-bomb defense). Everything runs on your machine, nothing is uploaded.
No. Compressing and unpacking both run locally in the browser (the self-hosted JSZip); files never leave the machine, reloading clears everything, and the page has no upload endpoint - verify it in the developer tools Network panel.
