How to send files that are too big for email: 7 best options (ranked)

If you’re searching for how to send files that are too big for email, you’re probably trying to finish a real job: get a 6GB export to a client, deliver a wedding gallery tonight, or send a project folder without it bouncing back.

The fastest fix is to use a transfer link (not an email attachment). You upload once, send a link, and the recipient downloads in full quality. Below are the best options, ranked by how reliably they work for creative delivery, plus what to pick when your upload keeps failing.

Before you pick an option: why email attachments fail

Email providers cap attachment sizes (and they can differ between sender and recipient). Even when your mailbox lets you attach something big, the receiving server may reject it. On top of that, email isn’t built for multi-gigabyte retries: one hiccup and your send restarts or fails.

The practical rule is simple: if it’s more than a few hundred MB, treat email as a message channel and move the file delivery to a link.

Ranked: the 7 best ways to send files that are too big for email

1) A dedicated transfer link (LetsSend)

What it is: You upload files in your browser, get a link, and email or message the link to your client. The transfer is designed for one-off delivery rather than long-term storage.

Why it’s ranked #1 for creative delivery: It avoids the two most common client problems: inbox limits and “please sign in” walls. It also keeps the handoff clean: one link, one download.

• Pros: Free transfers up to 5GB per transfer (as of August 2026), links expire automatically (Free: 7 days), optional password protection, and files upload straight from your browser to encrypted object storage (not relayed through a middle server).
• Cons: Not meant to behave like a shared working folder with ongoing edits and comments.
• Best for: Sending final exports, deliverables, galleries, stems, or a whole project ZIP when the goal is “download this” not “collaborate for weeks”.

Worth knowing (from running a transfer service): The most reliable large uploads use multipart (chunked) uploads under the hood. That means if cafe Wi‑Fi drops for 5 seconds, you don’t necessarily lose the whole upload. If you’ve ever watched a 9GB upload hit 99% and fail, you understand why this matters.

LetsSend specifics (accurate as of August 2026): Free allows 5GB max per transfer, a 5GB daily allowance, up to 10 files per day, and 7-day link expiry. Pro allows up to 200GB per transfer, link expiry up to 30 days, and can add a download limit. Accounts are passwordless (short code emailed to you), so there is no password to leak.

If you want the shortest path to done, you can send a file free, then adjust link controls in see all features. If you’re deciding based on size and expiry, compare Free and Pro.

2) Another WeTransfer-style transfer link service

What it is: Same basic workflow: upload, get a link, send it. These tools are popular because they match the mental model of “email, but for big files”.

• Pros: Usually the cleanest recipient experience for one-off delivery. Often includes expiry and basic link management.
• Cons: File-size caps, expiry lengths, and password protection vary a lot by provider and plan. Some also add branding or extra screens that slow clients down.
• Best for: Simple, occasional sends when you already know your recipient can download promptly.

Trade-off honesty: if your job requires audited access, strict data residency, or enterprise controls, a simple transfer-link tool may not be enough. In that case, jump to the SFTP or managed platform options below.

3) Cloud storage share links (Google Drive, Dropbox, OneDrive)

What it is: You upload into a storage account, then share a link to a file or folder with permissions (viewer/editor).

• Pros: Great for ongoing collaboration, version history, and shared folders that live longer than a delivery link.
• Cons: The #1 real-world failure is permission friction: “Request access”, “Sign in to continue”, or opening a shared folder on a phone and not finding the right download button. Also, sending a folder often means the recipient must download a ZIP, which can confuse non-technical clients.
• Best for: Long projects with many rounds, shared working files, and situations where both sides already use the same ecosystem.

4) Client proofing and delivery platforms (photo/video review tools)

What it is: Tools built for client review (comments, approvals, sometimes watermarking or galleries) with delivery baked in.

• Pros: Excellent for structured feedback and sign-off. Often better than “please comment on this email thread” chaos.
• Cons: More setup, more decisions, and sometimes heavier UI than you want when the job is simply “download these files”.
• Best for: Video review cuts, photo selections, approvals, and projects where feedback is the deliverable, not just the files.

5) Physical delivery (USB drive or external SSD)

What it is: Put the files on a drive and hand it over (or courier it).

• Pros: Works when internet is slow, expensive, or unreliable. Great for truly huge deliveries (hundreds of GB to TB).
• Cons: Slow logistics, risk of loss, and version confusion (“Is the drive the latest export or the one from Tuesday?”). Also, some clients cannot plug in external drives due to IT policies.
• Best for: Feature-length footage, massive archive handoffs, rural locations, or situations where upload time would blow your deadline.

Lived detail that matters: If you’ve ever tried to upload from a hotel Wi‑Fi that kicks you off every hour, a couriered SSD can be the difference between delivering on time and spending your evening watching an upload bar.

6) FTP/SFTP (server-based file transfer)

What it is: A classic way to move files to a server, usually with usernames and passwords. SFTP encrypts the connection.

• Pros: Reliable for teams with IT support, clear account-based access, and works well in established pipelines.
• Cons: Setup and client experience are rough if you’re sending to non-technical recipients. Also easy to misconfigure permissions, and “where do I upload this?” becomes a support request.
• Best for: Agency or studio pipelines, broadcast workflows, or when a client requires server-based delivery.

7) Compress, split into parts, and send in pieces (last resort)

What it is: You ZIP the files, split into multiple parts, and send each part through whatever channel you can (email, chat, multiple uploads).

• Pros: Sometimes it’s the only option when a platform blocks big uploads and you cannot use links.
• Cons: High failure rate. If the recipient misses one part, nothing opens. Also, compressing already-compressed media (H.264/H.265 video, JPEGs) usually wastes time without shrinking much.
• Best for: Emergency delivery when policy or tech constraints leave you no better choice.

Security note: ZIP “passwords” are not all equal. Some ZIP encryption is weak or inconsistently supported. If security is the reason you’re splitting files, a link with password protection is usually the cleaner path.

How to choose the right option (a quick decision guide)

• You need the client to download once, with minimal fuss: use a transfer link (option 1 or 2).
• You and the client will collaborate for weeks: use cloud storage (option 3).
• You need feedback and approvals inside the tool: use a proofing platform (option 4).
• Your internet is the bottleneck: consider physical delivery (option 5).
• A client has strict IT requirements: ask if they prefer SFTP or a managed portal (option 6).

Make big transfers less painful: 9 fixes when uploads fail

Most “my large file won’t send” problems are not about the file. They’re about flaky networks, sleeping laptops, or browsers running out of patience.

1. Use a wired connection if you can. It’s boring advice because it works.
2. Turn off VPN temporarily (unless you need it for policy). Some VPNs cause stalls on large uploads.
3. Keep your laptop awake. Disable sleep until the upload completes. Yes, even “close lid to keep it tidy” can pause uploads.
4. Prefer one folder ZIP over 3,000 tiny files. Many small files add overhead and can time out. Zipping doesn’t have to mean compressing; it can simply bundle.
5. Export smart. Don’t re-compress already-compressed video just to “make it smaller” unless you’re changing bitrate intentionally. You can lose an hour to a transcode and save 3%.
6. Try a different browser. If one browser extension or setting interferes, switching can be faster than debugging.
7. Upload in off-peak hours. If your home connection crawls at 7pm, schedule delivery earlier or later.
8. Send one link per milestone. Name it clearly (Final, V2, Approved) so nobody downloads the wrong one.
9. Test the download like a client would. Open the link in a private window on your phone. If it’s confusing for you, it’s confusing for them.

Privacy and retention: what happens to your files after you send them

Not all “send a link” tools treat your files the same way. Some are designed as storage first (keeping files until you delete them), others as transfer first (deleting when expired).

At LetsSend, we do not sell files or contact details, and expired transfers are deleted rather than quietly archived. Links also expire automatically, and can be password protected (plus download limits on Pro). If you want to verify the policies behind this advice, see how we handle your data and the team behind LetsSend.

A simple “send it and move on” checklist

• Bundle cleanly: one folder, one ZIP if needed, clear naming.
• Pick the right channel: transfer link for delivery, cloud storage for collaboration.
• Set expectations: tell the client file size and the link expiry date.
• Add protection when appropriate: password for sensitive work, and a shorter expiry for private client material.
• Confirm receipt: ask for a quick “downloaded” reply before you archive your project.

If you want the simplest option for one-off delivery

We build LetsSend, so disclosure: it’s our tool. If your goal is to send something too big for email with minimal client friction, you can send a file free (up to 5GB per transfer on Free, as of August 2026). If you hit size or expiry limits, compare Free and Pro to see whether Pro’s 200GB transfers and longer expiry fit your workflow.

If you run into a specific edge case (folder structure, failed uploads, or recipient issues), visit the Help Center or contact us and we’ll point you to the most reliable fix.
