How to Send 20GB Files for Free (Without Compressing Them)

To send a 20GB file for free, use a file transfer service with a high or unlimited size cap, or upload it to a cloud drive with enough free storage and share the link. Email is out of the question — Gmail and Yahoo cap attachments at 25 MB and Outlook at 20 MB, roughly 1/1000th of what you need — and most free transfer tools stop around 2 GB. The realistic free routes are a generous transfer service, a cloud drive whose free tier actually fits 20 GB, or, as a last resort, splitting the file into parts.

A 20GB file is usually raw video footage, a project archive, a disk image, or a game build — content that often cannot be meaningfully compressed because it is already encoded. This guide covers which free options genuinely handle 20 GB, how long the upload will take on your connection, and the exact steps to send it.

Why Does a 20GB File Break Most Free Tools?

Free file-sharing tiers are designed around everyday documents and photos, not 20GB payloads. The typical ceilings you will run into (limits change, so always check the current number):

• Email attachments: 25 MB on Gmail and Yahoo, 20 MB on Outlook — 20 GB is roughly 800–1,000 times over the limit.
• Free transfer tools: most well-known services cap free transfers at around 2–3 GB per send.
• Cloud drive free tiers: Google offers 15 GB of free storage shared across Drive, Gmail, and Photos — a 20GB file simply does not fit. Other free tiers commonly start even lower, around 2–5 GB.
• Messaging apps: per-file limits are typically around 2 GB.
• Browser timeouts: even where the cap allows it, a multi-hour upload without resumable transfer can fail at 95% and force a restart.

That last point matters. For a file this size, you want a service with chunked, resumable uploads so a brief Wi-Fi drop resumes the transfer instead of destroying hours of progress. For context on how big these numbers really are, see our explainer on how much 1 TB of storage actually holds.

What Are the Realistic Ways to Send 20GB for Free?

Option 1: A free file transfer service with high limits (easiest)

Dedicated transfer services are built for exactly this job: you upload once, the recipient gets a download link, and the files expire automatically so nothing clutters anyone's storage. With EveryTransfer you can send up to 1 GB per transfer with no account at all, and a free-forever account unlocks higher limits — with paid plans going further still for files in the 20GB class. Recipients never need an account, uploads are chunked and resumable, and every transfer can carry a password, custom expiry date, and download limit. Compare current tiers on the plans page.

Option 2: A cloud drive free tier — if the storage math works

Uploading to Google Drive or OneDrive and sharing a link works for large files — but do the math first. Google's free 15 GB is shared across Gmail and Photos, so a 20GB file will not fit even on a fresh account. OneDrive's free tier is 5 GB. The workarounds add friction, and the file then sits in your storage until you remember to delete it. Cloud drives shine for ongoing access; transfer links shine for one-time delivery.

Option 3: Split the file into parts (last resort)

Free tools like 7-Zip can split a 20GB file into ten 2GB volumes that fit under almost any free cap; the recipient downloads all parts and 7-Zip reassembles them. It works — but it multiplies the steps, confuses non-technical recipients, and one missing part makes the whole archive unusable. Treat it as the fallback when no single-link option exists.

How Long Does It Take to Upload 20GB?

Upload time depends on your connection's upload speed, which is usually much lower than the download speed on your plan. At a steady rate, 20 GB (160,000 megabits) takes approximately:

• 10 Mbps upload (basic broadband): about 4.5 hours
• 25 Mbps upload (typical cable): about 1 hour 45 minutes
• 50 Mbps upload (fast cable / entry fiber): about 55 minutes
• 100 Mbps upload (fiber): about 27 minutes
• 500 Mbps upload (fast fiber): about 5–6 minutes
• 1 Gbps upload (full fiber): about 3 minutes

Real-world times run 10–20% longer than these ideals due to protocol overhead and network variation. Two practical tips: use a wired connection if the upload will take more than an hour, and prevent your computer from sleeping mid-transfer.

Step-by-Step: How to Send a 20GB File

1. Check the file's real size. Right-click the file (or folder) and confirm whether it is 20 GB or 20 GiB — the difference can push you over a cap.
2. Pick your route. A transfer service with a sufficient limit is the one-link option; otherwise use a cloud drive with free space, or split the archive.
3. Upload over your most stable connection. Wired beats Wi-Fi for multi-hour uploads, and resumable uploads protect you from drops either way.
4. Set transfer options. Add a password and expiry date if the content is sensitive, and a download limit if it should only be fetched once.
5. Send the link and confirm receipt. With download notifications turned on, you will know the moment your recipient has the file.

"For a 20GB send, the upload happens once but the link can be downloaded by many people. Upload it a single time and share the link with the whole team — never email it twice."

Frequently Asked Questions

What is the fastest way to send a 20GB file?

Over the internet, the fastest way is a direct upload to a transfer service from the fastest upload connection you can access — on gigabit fiber that is roughly 3 minutes of upload time. If both people are in the same building, a USB 3 flash drive or a direct cable transfer is faster still. Across distance, nothing beats a single resumable upload plus a download link.

Does zipping a 20GB file help?

Usually not much. Video, photos, music, and most archives are already compressed, so zipping them again typically saves only 1–5% — not enough to change which tools you can use. Zipping does help when you are sending thousands of small files (it bundles them into one upload) or when the content is text, raw data, or uncompressed project files, which can shrink 50% or more.

Is splitting a file into parts safe?

Yes — split archives are a mature, well-tested format, and tools like 7-Zip verify integrity when reassembling. The risks are practical rather than technical: if any single part fails to download or gets deleted before the others, the archive cannot be opened, and recipients unfamiliar with split files often get stuck. Send all parts through one link and include a one-line instruction ("download all parts to the same folder, then open part 1").

Can I email a 20GB file through Gmail?

Not as an attachment — Gmail's 25 MB cap is about 800 times too small. Gmail will offer to upload the file to Google Drive and insert a link instead, but a 20GB file exceeds the free 15 GB of Drive storage. See our full guide on how to send large files via Gmail for the workarounds and their limits.

Sending 20 GB for free is entirely doable: pick a transfer service whose limit covers the file, upload once over a stable connection, and share a single link that expires when the job is done. EveryTransfer lets you start without an account, keeps uploads resumable so hours of progress are never lost, and gives every transfer password protection and expiry controls — and if you outgrow the free tier, our roundup of the best WeTransfer alternatives shows how the options compare.
