File to ZIP

Drop a file into the zip-file creator and click Zip to get a .zip archive in seconds. Text and source code compress 60-80%; photos and PDFs barely shrink because they are already encoded. No install, no account.

Compression effectiveness depends on what is inside the file. Text, code, JSON, and CSV inputs typically shrink 60-80%; Office documents 10-25%; PDFs 5-15%; already-compressed photos (JPG, PNG, HEIC) only 0-5% - for those, compress with an image tool first, then zip. The "Reduce ZIP file size - what to expect" table on the tool page shows the math for hitting common targets like the 25 MB email attachment cap. For sensitive content, open the Settings panel on the creator and add a password before zipping - three encryption strengths are available (Standard, AES-128, AES-256). Send the password through a different channel than the archive itself.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
  • Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
  • Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
  • Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
