How ZIP multiple files compression works
ZIP Multiple Files bundles a selection of files into a single .zip archive directly in your browser. It’s a fast way to share a mixed set of documents, images, or assets as one download — with no uploads.
When you add files, your browser reads them locally and streams them into the ZIP as it’s built. There are no server transfers: FileYoga never receives your files or the finished archive. Very large selections can be limited by your browser’s memory and performance.
When to use this tool
Use ZIP Multiple Files when you want to keep a group of files together in one tidy package:
- Sending multiple attachments as one ZIP instead of many separate files
- Bundling project assets (docs + images + audio) for a teammate or client
- Sharing a selection of photos without creating a whole folder ZIP
- Archiving a set of files before uploading to a drive
Step-by-step: from files to ZIP
Creating a ZIP takes just a few steps:
- Pick your files. Click the tool area and choose a file, or drag and drop files from your desktop into the box.
- Review what’s included. Each file appears in the list with its name, file count and total size so you can see what will be zipped.
- Choose your settings. Adjust the compression level and decide whether to keep subfolders and paths or flatten everything into one level.
- Compress to ZIP. Click Compress to ZIP. Your browser compresses each file on your device without uploading the contents.
- Save your ZIP files. Save ZIPs one by one, or use Save all ZIP files to download every completed archive in a few clicks.
Privacy, limits and how this tool treats your files
FileYoga is built around a simple rule: your files stay with you. ZIP Multiple Files follows that rule closely.
Local-only zipping
Your files are read and compressed in your browser. Nothing is uploaded to FileYoga servers.
No hidden copies
When you clear the list or close the tab, the tool stops using your files and does not store them online.
No artificial limits
No paywalls or quotas. Practical limits come from your device’s memory and your browser.
No account required
Open the page, create your ZIP, download it, and leave — no sign-up needed.
Key limitations: very large file selections can exceed browser memory, this tool does not add password encryption, and folder-path preservation depends on what your browser provides when selecting/dragging files.
Picking a compression level
Compression is a trade-off between speed and ZIP size. Higher compression can reduce size but may take longer, especially with many small files.
Best when you care more about speed than the smallest possible size. Good for huge batches on slower machines.
A solid everyday setting that keeps ZIP creation snappy while still trimming size where possible.
Aims for the smallest ZIP size. Can be slower on large batches, especially with many small files.
Folder structure and file paths
The “Keep subfolders and paths” option affects how paths are stored when your browser provides them.
- Enabled: If your file selection includes relative paths, the ZIP will mirror them.
- Disabled: Files are stored as a flat list inside the ZIP (same folder level).
Note: when you pick files individually, some browsers don’t provide folder paths at all — in that case, the ZIP will be flat either way. If you need guaranteed folder structure, use Folder to ZIP.
Tips for best results
- For huge selections, start with a lower compression level to reduce memory pressure.
- Keep the browser tab open during compression — closing it will interrupt the ZIP build.
- If you need folder structure preserved, prefer zipping the entire folder using Folder to ZIP.
- Avoid extremely long file names/paths when possible to reduce compatibility issues.
- Make sure you have enough free disk space to download the finished ZIP.
Troubleshooting
- The tab freezes or gets very slow: you may have selected too many files or very large files. Try a smaller batch or lower compression level.
- The ZIP is missing some files: retry with fewer files, and ensure none are locked by another app.
- The ZIP won’t open after download: re-run compression and ensure the download completed; try smaller batches for very large jobs.
Frequently asked questions
No. ZIP Multiple Files runs locally in your browser. Your files are never uploaded to FileYoga servers.
No artificial limit, but very large selections can hit browser memory limits or take a long time—especially with thousands of small files.
No. This tool does not add password encryption. If you need an encrypted ZIP, create the ZIP here and then encrypt it using a dedicated encryption tool.
Only if your browser provides folder paths for the selected files. If you need guaranteed folder structure, use Folder to ZIP instead of selecting files individually.
Huge batches and high compression levels require more CPU and memory. Try fewer files per ZIP or lower the compression level for faster results.
The output is a standard .zip archive that opens with built-in tools on Windows and macOS, and with common apps on iOS and Android.
Re-run compression and make sure the download completes. For very large jobs, compress in smaller batches to reduce the chance of memory-related failures.
