Why zip files?
A single ZIP is easier to email, upload or share than dozens of separate files, and it keeps folders and names intact. ZIP is opened natively by Windows, macOS, iPhone and Android, so the recipient doesn't need extra software.
How much will it shrink?
Text, documents, spreadsheets and code often compress by 60–90%. Photos, videos, MP3s and other already-compressed files barely shrink, so Fylo stores them without recompressing — that keeps zipping fast. Choose None to store everything for maximum speed, or Maximum for the smallest archive of text-heavy folders.
Sharing big folders
Email services usually cap attachments at 20–25 MB, so for large folders zip first and share the ZIP through cloud storage or a file-transfer service. Zipping keeps the folder structure intact, so the recipient sees exactly what you organised. For photos and videos choose None, which is much faster and produces almost the same size.
| Level | Speed | Best for |
|---|---|---|
| None | Fastest | Photos, videos, music |
| Normal | Fast | Mixed files |
| Maximum | Slower | Text, documents, code |
Frequently asked questions
Can I zip a whole folder?
Yes — click Choose a folder; subfolders and names are kept.
Is there a size limit?
Only your device's memory. Archives of several hundred MB work on laptops.
Can I password-protect the ZIP?
Not yet — encryption support is planned.
Will the ZIP open on a Mac?
Yes, ZIP opens natively on macOS, Windows, iOS and Android.
Does it keep file dates?
Yes, each file's last-modified date is stored in the ZIP.
Can I add more files after choosing a folder?
Yes, drop or choose more files before clicking Create ZIP.
Are my files uploaded to a server?
No. Create ZIP runs entirely in your browser — your files are processed on your own device and never sent anywhere. Once the page has loaded, it even keeps working if your connection drops.
