Package files and folders into a ZIP, then browse or extract archives locally with integrity checks.
Create one archive from files or a folder
Add files or choose a folder. Folder selection preserves relative paths, but empty folders are omitted. Review and edit paths before creating the archive. Use at most 500 files, 25 MB each and 50 MB combined. Choose a ZIP filename and compression level. Store skips compression, Fast prioritizes speed, Balanced is the default, and Maximum may take longer without making already-compressed files smaller. Create the ZIP and download the result. No files are uploaded; creation runs in a cancellable worker. Highly compressible files may be stored to stay within the extractor's expansion-ratio protection. Output must fit within 50 MB; encryption and ZIP64 are not provided.
Extract one file or everything
ZIP Viewer & Extractor checks stored and Deflate archives up to 50 MB, 500 entries, 25 MB per file and 100 MB expanded. Download one file, or use Extract all to verify every entry and download the actual files separately. Browsers control multiple-download permissions and may ask to allow the batch or block it; individual links remain available after extraction. Separate downloads omit folder paths and add numbered filename suffixes for duplicates. Where supported, Save to folder asks for a destination and writes verified files into a new subfolder. It does not replace existing folders; cancellation or a write error can leave partial output. Unsafe, conflicting, encrypted, symlink, ZIP64 and multi-disk archives are rejected. CRC verifies integrity but is not a malware scan. Open only files you trust.
