Does Deliteful protect against zip bombs?

Yes. Extraction is capped at 5 GB of total uncompressed output per task. Archives exceeding that limit are skipped automatically, preventing runaway decompression from consuming server resources or returning unusable output.

Are path traversal attacks blocked?

Yes. All extracted file paths are validated before writing. Any entry containing '../' or absolute path references is rejected, preventing files from being written outside their isolated extraction directory.

Is the original ZIP modified?

No. The original uploaded file is never modified. Deliteful works on a server-side copy and returns only the extracted contents.

What happens if the ZIP is corrupted?

Corrupted archives are detected during the pre-extraction verification step and skipped. Other ZIPs in the same batch continue to process normally.

Safe ZIP Extraction for Software Developers

Developers routinely receive ZIP-packaged builds, assets, and dependency bundles that need unpacking before use. Deliteful extracts your ZIP archives in an isolated server environment with automatic path traversal blocking and decompression bomb protection — so you never have to worry about malicious archive contents corrupting your local filesystem.

ZIP files from third-party vendors, CI/CD artifact drops, or client handoffs can contain unexpected directory structures or oversized contents. Manually unzipping on your local machine carries real risk: path traversal exploits (files writing to '../' destinations) and zip bombs that expand to gigabytes can both cause damage before you notice. Deliteful verifies each archive before extraction and blocks these attack vectors automatically.

Each ZIP is extracted into its own isolated temporary directory, preserving the original internal folder structure. Corrupted archives are skipped rather than halting the batch. Extracted files are bundled for immediate download. The extraction safety cap is 5 GB per task — sufficient for most build artifacts and asset packages.

How it works

1
Upload your ZIP
Drag your ZIP archive into the uploader — up to 50 MB per file, 50 files or 2 GB per batch.
2
Automatic safety checks run
Deliteful verifies the archive integrity and blocks path traversal patterns before any extraction begins.
3
Download extracted files
Your files are returned in their original folder structure, ready for immediate use.
