How to Send Large Files to Clients Without Email

The Email Attachment Problem

Email has a 25 MB attachment limit. That’s fine for a Word document. It’s useless for:

• Video files (even a 1-minute 4K clip is 500 MB+)
• Design packages (Figma exports, brand kits, font collections)
• Development builds (ZIP archives of compiled code)
• Photography deliveries (RAW files, high-res exports)
• Audio files (uncompressed WAV, multi-track sessions)

So what do most people do? They use WeTransfer. Which works — until the link expires in 7 days and the client emails asking for the file again. Or until you have a revised version and have to send a new link, creating version confusion.

There’s a better way to send large files to clients.

Why WeTransfer Isn’t the Answer

WeTransfer solves the size problem but creates new ones:

• Links expire — 7 days on free, 1 year on Pro, but always a countdown
• No updates — new version means new link means new email
• No version history — can’t compare v1 and v2
• No client feedback — clients have to switch to email to comment
• No analytics — you don’t know if they’ve even opened it

For a one-off transfer between friends, WeTransfer is fine. For professional client delivery, it’s a temporary solution to a permanent problem.

The Right Way to Send Large Files to Clients

The professional approach uses a permanent delivery link — a URL that:

• Never expires
• Updates automatically when you upload a new version
• Lets clients preview without downloading
• Tracks when the client views or downloads
• Accepts client feedback in context

Step-by-Step: Sending Large Files to Clients

Step 1: Prepare your file

Before uploading, make sure your file is:

• In the correct final format (not a working file)
• Named clearly (not “final-v3-ACTUAL.zip”)
• Compressed if possible (ZIP archives, compressed video)

Quick compression tips:

• Video: Use HandBrake to compress without visible quality loss
• Images: Use TinyPNG or Squoosh for web-ready exports
• Design packages: ZIP the folder before uploading
• Audio: Export at the agreed format (WAV for masters, MP3 for previews)

Step 2: Upload to Clowd

1. Go to clowd.host
2. Create a new delivery → select “File Delivery”
3. Upload your file (up to 500 MB on Pro Max)
4. Your file is live on a permanent URL instantly

Step 3: Share the link

One message. One link. Done.

Hi [Client],

Your [deliverable] is ready: https://clowd.host/a/[your-link]

No login needed — you can preview and download directly from the link.
Let me know if you have any feedback.

Step 4: Update without resending

When you have a revised version:

1. Upload the new file to the same Clowd delivery
2. Ping the client: “Updated — same link”

The URL never changes. No new email. No version confusion.

ZIP archives (assets, code)	< 500 MB	Clowd Pro Max
Short video (< 5 min, compressed)	< 500 MB	Clowd Pro Max
Long video / raw footage	> 500 MB	Compress first, or use Filemail + Clowd link
RAW photo collections	> 1 GB	External storage + Clowd delivery link

Practical Examples by Profession

Video Editor

You’re delivering a 3-minute brand video to a client. Compressed H.264 at 1080p is around 300 MB.

1. Export from Premiere/DaVinci at the agreed spec
2. Upload to Clowd
3. Client gets a permanent link with an in-browser video preview
4. When you deliver the revised cut, upload to the same link
5. Client can compare v1 and v2 in the version history

Photographer

You’re delivering 50 high-res JPEGs from a product shoot. Total: ~400 MB.

1. Export from Lightroom at full resolution
2. ZIP the folder
3. Upload to Clowd
4. Client gets a permanent link with a gallery preview of all images
5. When you deliver the retouched versions, upload to the same link

Developer

You’re delivering a compiled app build to a client for testing. ZIP is 180 MB.

1. Build and zip the output
2. Upload to Clowd
3. Client gets a permanent download link
4. When you push a new build, upload to the same link — client always has the latest

Designer

You’re delivering a complete brand kit: logos (SVG, PNG, PDF), fonts, brand guidelines. Total ZIP: ~250 MB.

1. Organise all assets into a clean folder structure
2. ZIP the folder
3. Upload to Clowd
4. Client gets a permanent link with a preview of the ZIP contents
5. If you add assets later, upload the updated ZIP to the same link

Best Practices for Large File Delivery

• Compress before uploading — smaller files upload faster and preview better
• Use descriptive file names — “BrandKit-v2-April2026.zip” not “assets-final.zip”
• Enable download controls — prevent clients from downloading before final payment using Clowd’s access controls
• Set a password for sensitive files — add a password to the delivery link for confidential work
• Track downloads — Clowd analytics show you when the client downloaded the file, so you know when to follow up

Question-Based Insights

Why do email providers have a 25 MB attachment limit?

Email servers weren’t designed for large file transfers. The 25 MB limit exists to prevent server overload and abuse. It’s been the standard for decades and is unlikely to change. File delivery platforms are the correct solution for anything larger.

What’s the difference between file transfer and file delivery?

File transfer (WeTransfer, SendAnywhere) is a one-time operation — you send a file, the recipient downloads it, the link expires. File delivery (Clowd) is an ongoing relationship — you maintain a permanent link that updates when you have new versions, and the client can always access the latest.
