Veelgestelde vragen

Which file types can I add to a ZIP?
Any file type works — documents, images, audio, and binaries are stored as-is inside the archive without format conversion.
How much compression should I expect?
Text and uncompressed formats shrink noticeably. Already compressed formats like JPG, MP4, or ZIP contents may barely change size.
Are files uploaded to SeerKits servers?
ZIP creation runs entirely in your browser using local memory. Nothing is uploaded and no account is required.
