Modify filenames and relative folder paths inside any ZIP archive without manual extraction and re-zipping. Edit names inline 100% locally in your web browser.
Select or drop any .zip file to parse and list all internal files and directory paths.
Type your new filenames or modify path strings directly inside the visual editor inputs.
Click "Rename ZIP" to rebuild the archive in memory and save your updated .zip file.
Modify file header paths directly without extracting files to disk, saving time and disk space on large archives.
Edit both base filenames and parent directory prefixes (e.g. assets/img.png to media/img.png) directly in the input fields.
Raw file bytes are mapped into the updated header structure without re-compressing quality-sensitive media files.
Renaming Files Inside Zip Archives Without Full Extraction: Modifying file names or directory paths within a zip container can be performed without decompressing payload binary streams. Renaming updates Local File Header filename string fields and patches the corresponding Central Directory Records directly.
Batch Renaming Patterns & Extension Normalization: Apply automated string patterns across archive contents: prefix/suffix appending, search-and-replace string substitutions, case conversions (UPPERCASE/lowercase), and file extension fixes (e.g. .jpeg to .jpg).
100% In-Browser Archive Header Patching: File renaming and zip catalog updates execute entirely within local browser WebAssembly RAM memory. No archive files, folder paths, or renamed records are uploaded to remote servers.
