Build your ZIP

Upload files or a whole folder, choose a compression profile, then build one ZIP archive locally in your browser. Already-compressed formats like JPG, MP4, MP3, and existing ZIP files may not shrink much further.

Base64 Encoder / Decoder Encode text or files to Base64 and decode Base64 back to readable text or downloadable files in a browser-first workflow that stays on your device. Bulk Rename Files Batch rename files or images with numbering, find and replace, date patterns, and cleaner filenames when you need a faster way to organize uploads. Diff Checker Compare two text blocks side by side with inline change highlights when you need to review edits, pasted drafts, code snippets, or document revisions.

What to Expect

Create one ZIP archive from multiple local files or a folder upload, choose a compression profile, and download the result without sending the source files to a remote archiving service.

Browse Utility Tools

Best for

  • Bundling project files, handoff folders, or email attachments into one archive.
  • Quick browser-side ZIP packaging when you do not want to install another utility.
  • Keeping folder structure where the browser exposes relative paths.

Not ideal for

  • Very large batches that will stress browser memory on older devices.
  • Expecting big size savings from already-compressed files like JPG, MP4, MP3, or ZIP.
  • Archiving empty folders when the browser does not expose them.

What this tool keeps

  • A focused single-task interface with clear limits and copy-ready output.
  • The convenience of handling the job directly in the browser where supported.
  • Fast access to practical utilities without signups or forced app installs.

What may need cleanup

  • Browser performance can vary by device, especially on large local files.
  • Some outputs still need a quick human check before you rely on them.
  • Browser feature support can affect folder upload, timezone data, or clipboard access.

Common errors

  • Pasting invalid text or encoded data and expecting the tool to guess the right format.
  • Assuming every file type compresses well inside a ZIP archive.
  • Using the wrong time zone name or measurement category for the task.

Example use cases

  • Create one archive for client delivery, support tickets, or admin uploads.
  • Package many screenshots or exports into a single cleaner download.
  • Bundle a folder before moving it to cloud storage or email.

Sample input

A mix of documents, screenshots, exports, or one selected folder from your device.

Sample output

One ZIP archive containing the selected files with the original names and folder paths where supported.

Who this is for

  • Office admins, support teams, designers, students, and anyone packaging files quickly.

Frequently Asked Questions

Does ZIP Compressor upload my files to a server?

No. ZIP Compressor builds the archive in your browser, so your files stay on your device during compression.

Can I upload a whole folder?

Yes. On browsers that support folder uploads, you can pick a directory and keep its nested structure inside the ZIP.

Will ZIP compression always make files smaller?

No. Already-compressed files such as JPG, MP4, MP3, and existing ZIP files may shrink very little, while text-heavy files usually compress better.

What file limits apply?

The current browser-side limits are up to 200 files, 100MB per file, and 250MB total per ZIP build.
