What this tool does

Bundle selected files into one ZIP archive entirely in your browser without uploading the file contents to FileLume.

How it works in FileLume

  • The browser reads the selected files and passes them to the local archive helper.
  • FileLume returns one archive.zip download after the in-memory ZIP has been created.

Best for

  • Bundling related documents or images into one download.
  • Preparing several files for email, storage, or transfer.
  • Keeping a batch together without changing the individual file formats.

Format and quality guidance

  • ZIP bundles files; it does not merge documents or convert their formats.
  • Already compressed formats such as JPG, MP4, PDF, and ZIP may show limited size reduction.

Trade-offs to expect

  • Creating a large archive requires browser memory for the selected files and generated ZIP.
  • Compression savings depend on the source formats and repeated data.

Limitations

  • Very large batches can exceed browser memory or take a long time on mobile devices.
  • The current tool creates one flat archive and does not expose advanced encryption or folder rules.

Common errors and fixes

The ZIP is not much smaller.
The source files may already be compressed; use ZIP mainly to bundle them together.
The browser becomes unresponsive.
Create smaller archives or use fewer large files per batch.
A recipient expects one PDF.
Use Merge PDF instead; ZIP keeps files separate.
