Your email provider is probably blocking it before it even leaves the outbox, because most filters reject .zip attachments outright to stop malware. Project archives also stack up in size fast. Hand recipients a UploadWings download link instead, and the complete archive arrives intact and filter-free.
Many email providers and corporate filters block .zip attachments outright to guard against malware, so your archive may never reach the inbox.
A ZIP that bundles a whole project (assets, exports, documents) quickly exceeds attachment limits even when individual files are small.
Recipients need the archive to arrive complete and uncorrupted, since a partial ZIP won't extract.
Typically created in Windows, macOS, 7-Zip, WinRAR — usually sent by anyone bundling multiple files or a full project into one download.
Go to uploadwings.com in any browser. There's no sign-up and nothing to install to send your ZIP file.
Drag and drop your ZIP archive onto the upload area, or click to browse for it. You can add more files to the same transfer if you need to.
Choose how long the link should stay active, and add a password if the file is sensitive. Files auto-delete when the link expires.
When the upload finishes, copy the instant download link or QR code and share it via WhatsApp, email, or anywhere. Your ZIP file is on its way.

Attachment limits are set by each provider and change over time. UploadWings lets you send ZIP archives up to 5.0 GB on the free tier without an account.
Many providers reject .zip files because archives can conceal malware. A download link sidesteps that filter while still delivering the exact archive.
You can send large archives on the UploadWings free tier without an account, and the recipient downloads the complete ZIP from a single link.
