  4. Create the ZIP and download it.

About the ZIP File Creator

The ZIP File Creator packs any set of files into a single .zip archive inside your browser, with a choice of compression level and nothing uploaded anywhere. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Sending several files as one attachment.
  • Packaging a set of documents without installing anything.
  • Bundling files on a locked-down work machine where you cannot install a zip tool.

Details

RunsEntirely in your browser — no upload, no server
CompressionDeflate, the standard ZIP method every tool can read
Store modeNo compression at all — fast, and right for files already compressed
EncryptionNot supported, and the page says so rather than pretending
Store mode is worth understanding rather than ignoring. It packages without compressing, which sounds pointless until you are bundling a folder of photos or videos — there deflate spends real time to save a fraction of a percent, and Store gives you the same archive in a moment.

Where this tool stops

Everything is held in memory while the archive is built, so very large sets — several gigabytes — will exhaust the tab before they finish. No encryption, and no split or multi-volume archives.

Frequently asked questions

Are my files uploaded anywhere?
No. The archive is built by JavaScript running in this page, using a library served from this site. Open your browser's Network tab and create an archive — you will see no request carrying your data, because there is none.
Why is my zip barely smaller than the files?
Because the files were already compressed. JPEG, PNG, MP4, MP3, PDF and Office documents all have compression built in, and deflate cannot squeeze what has already had its redundancy removed. Zipping them is still worth it to get one download instead of forty — that is packaging, not compression.
Can I password-protect the archive?
Not here. Real ZIP encryption is AES-256, and the library this page uses cannot write it. A tool that added a password field and produced an unencrypted archive would be worse than no tool, so there is no field. Use 7-Zip, or your operating system's built-in encryption, when you genuinely need it.
Are there any usage caps on the ZIP File Creator?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the utility.
Can you see what I put into this utility?
No. The ZIP File Creator runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What problem does the ZIP File Creator solve?
In practice it gets used for three things: sending several files as one attachment. Packaging a set of documents without installing anything. Bundling files on a locked-down work machine where you cannot install a zip tool. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything the ZIP File Creator cannot do?
Everything is held in memory while the archive is built, so very large sets — several gigabytes — will exhaust the tab before they finish. No encryption, and no split or multi-volume archives. Knowing where a tool stops being trustworthy matters more than the cases where it works.
What figures does the ZIP File Creator work from?
Runs is Entirely in your browser — no upload, no server. Compression is Deflate, the standard ZIP method every tool can read. Store mode is No compression at all — fast, and right for files already compressed. These are printed on the page itself, so you do not have to take them on trust.
How large a file can I use?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
