file.io: What It Is and How It Works
file.io is a free temporary file sharing service that lets you upload a file and get a shareable URL. Files are hosted for up to 14 days and then automatically deleted. No account is required to upload or download. The free plan supports files up to 2GB.
While file.io is a solid service for small files, it has limitations — the 2GB free limit rules out large video files, photo libraries, and project archives. In 2026, files-share.com is the better alternative: 10GB free (5x more), no account, no ads, and a 6-digit key that is simpler than any URL.

Detailed Reviews: file.io and Its Alternatives
file.io — Solid for Small Files
file.io is a reliable, clean service for files under 2GB. Key features:
- 2GB free limit — covers most documents, presentations, and small photo batches
- No account required — upload and share without signup
- No ads — clean download page
- 14-day expiry — the longest expiry among no-account temporary services
- One-time download option — the file can be set to delete after the first download
- API access — developers can upload files programmatically via the file.io API
The main limitation is the 2GB free limit. For files larger than 2GB — 4K video, RAW photo libraries, large project archives — file.io is not an option on the free plan.
files-share.com — Best Overall Alternative
files-share.com is the best alternative to file.io in 2026. Here is why:
- 10GB per upload — 5x more than file.io's 2GB. Covers 4K video, large archives, full photo libraries. No storage quota.
- No account on either end — sender and recipient both skip signup. No email, no password.
- No ads on download page — clean, professional experience. No countdown timers, no pop-ups.
- Full upload speed — no throttling. Uploads run at your actual connection speed.
- 6-digit key — simpler than any URL. Say it on a call, text it in 2 seconds, type it anywhere without errors.
- 10-day auto-deletion — files are permanently deleted after 10 days. Privacy by default.
- Any device, any browser — works on Windows, Mac, iPhone, Android, Linux. No app required.
Wormhole — Best for Encrypted Transfers
Wormhole offers 10GB free with end-to-end encryption and no account. The 24-hour expiry is very short — if your recipient cannot download within 24 hours, the file is gone. Best for time-sensitive encrypted transfers.
SendGB — Best for 5GB Without Account
SendGB offers 5GB free without an account. Upload speeds are throttled and the download page shows ads. For files between 2GB and 5GB, SendGB is an option but inferior to files-share.com.
WeTransfer — Most Recognizable
WeTransfer is widely known but requires an email address, shows ads, and limits free uploads to 2GB. Same limit as file.io but with more friction.
MEGA — Best for Permanent Large Storage
MEGA offers 20GB of free permanent storage. Requires an account. Best for long-term storage rather than one-time sharing.
Google Drive — Best for Teams
Google Drive offers 15GB of free permanent storage with Google Workspace integration. Requires a Google account. Best for team collaboration and long-term document storage.
file.io API vs files-share.com
| Feature | file.io API | files-share.com |
|---|---|---|
| Programmatic upload | Yes — REST API | No — browser only |
| Free limit | 2 GB | 10 GB |
| No account | Yes (free tier) | Yes |
| Best for | Developers, automation | Individuals, one-time sharing |
If you need to upload files programmatically (from a script or application), file.io's API is the right tool. If you need to upload and share files manually with no code, files-share.com is the better choice with 5x the size limit.
How to Use files-share.com (Best file.io Alternative)
