Create a ZIP or inspect and extract one safe entry.
Your input
Outputs are cleared when the input changes.
Result
Enter your data or use the example, then run the tool.
Worked example
The sample packs two generated text files. Reupload the ZIP in inspect mode and select index 0 or 1 to download each entry.
Method
JSZip creates actual DEFLATE ZIP files, reads central-directory sizes before extraction and downloads only the selected ordinary file. Entry names are displayed as text, never filesystem paths to write.
Limits
≤100 entries; each input ≤10 MiB, packing total ≤20 MiB, declared restored total ≤32 MiB and ≤100× ZIP size. Reject traversal, absolute/drive paths and duplicate input names. No password encryption, huge ZIP64 or CRC verification. Highly compressed legitimate archives can hit limits. ZIP metadata is untrusted; worker timeout also applies.
All work stays in this browser. Each disposable worker is terminated after 2.5 seconds or cancellation. Inputs and processing logs are not sent to analytics.
Your inputs stay on this device. Only optional, consented page visits are measured. Input values, files, filenames and processing logs are not sent to Analytics.
When switching languages, text, settings and selected files are temporarily kept on this device. Transfers are removed after restoring; interrupted transfers are cleaned up on a later visit. Inputs and files are never uploaded.
