ZIPto7Z
Drop your files here
Video, audio, images and documents: MP4, MP3, HEIC, DOCX, PDF and 40 more formats. Several files or a link at once.
Why convert
ZIP — the most common archive: Windows and macOS open it with no extra software. 7Z packs tighter than ZIP, especially text, spreadsheets and source code: a smaller archive to send or keep.
What changes in the file
The files inside do not change by a single byte: the archive is unpacked and packed again, keeping folders and file names. A password, the archive comment and symbolic links are not carried over. ZIP and 7Z do not keep Unix permissions (such as "executable").
Which settings to pick
"Compression": "Normal" suits almost everything; "Smaller file" trims a few more percent but takes longer; "Faster" is for content that is already compressed (photos, video) and will not shrink anyway.
