Dropbox vs WeTransfer vs Swyvl: The Best Way to Share Survey Data

For sharing survey data with clients, Swyvl is the best option because it solves both problems at once: file transfer and file viewing. Dropbox and WeTransfer are competent file transfer tools, but they deliver files your client cannot open — and that distinction matters more than most surveyors realise.

Let me break down all three platforms honestly.

The core problem with survey data delivery

Survey deliverables are not normal files. A marketing agency sends PDFs and PNGs. A video producer sends MP4s. These are formats that every computer on earth can open natively.

A surveyor sends LAS point clouds, GeoTIFF orthomosaics, E57 scan data, OBJ meshes, and DXF drawings. These formats require specialist software — software your client almost certainly does not have installed.

This means file transfer and file viewing are two separate problems:

1. Transfer: Getting a large file from your machine to the client
2. Viewing: Letting the client actually see and interact with the data

Dropbox and WeTransfer solve problem one. They do not solve problem two. When your client downloads a 4 GB LAZ file from Dropbox, they still have a file they cannot open. The delivery has technically succeeded and practically failed.

Dropbox: the default option

Most survey companies default to Dropbox because it is familiar. Everyone has used it. It handles large files. It syncs. It is reliable.

What Dropbox does well

• Shared folders: You can create a folder per client or per project, share it, and add files over time. This gives you some organisational structure.
• Sync: Files sync to the client’s machine automatically if they install the desktop app.
• File versioning: Dropbox keeps file history, so if you replace a deliverable, the old version is still accessible.
• Permissions: You can control who has access and revoke access later.
• Reliability: Dropbox has been around since 2007. It works. It does not lose files.

Where Dropbox falls short for survey work

• No spatial file viewing: Dropbox cannot preview LAS, LAZ, E57, GeoTIFF, OBJ, GLB, or any spatial format. Your client sees a filename and a download button — nothing more.
• No branding: The client experience is “Dropbox” — blue logo, Dropbox navigation, Dropbox interface. Your company identity is invisible.
• No audit trail: You cannot see whether a specific client opened a specific file, when they downloaded it, or from where. There is no delivery record for contractual purposes.
• Folder sprawl: Six months in, you have dozens of shared folders with inconsistent naming. There is no site-level or session-level organisation purpose-built for survey work.
• Cost at scale: Dropbox Business starts at $15/user/month. For a small survey team of five, that is $900/year before you consider storage costs for large spatial datasets.

WeTransfer: the quick option

WeTransfer is what you use when you need to send something now and do not want to think about it. Upload, enter their email, send. Done.

I wrote previously about why WeTransfer is not a professional survey data delivery tool. The short version: it is designed for one-off transfers, not ongoing professional relationships.

What WeTransfer does well

• Speed: No signup required for the free tier. Upload, enter email, send. The friction is genuinely low.
• Large files: Pro allows up to 200 GB per transfer, which covers most survey deliverables.
• Simple UI: Your client receives an email, clicks a button, downloads the file. No account required on their end.

Where WeTransfer falls short for survey work

• Links expire: Free links expire in 7 days. Pro links expire in up to 1 year. Survey data should be permanently accessible — it is a contractual record, not a temporary transfer.
• No viewing: Like Dropbox, WeTransfer provides zero viewing capability for spatial files. The client downloads a file they cannot open.
• No organisation: Each transfer is independent. There is no concept of a site, project, or session. After six months of transfers, neither you nor the client can find anything.
• No branding: WeTransfer’s interface dominates the experience. Your client sees WeTransfer, not your company.
• No download tracking: You get a notification that “your transfer was downloaded” but no detail on who downloaded what, when, or from where.
• No permanence: WeTransfer is transactional. Once the link expires, the data is gone. There is no persistent library of deliverables.

Swyvl: purpose-built for survey delivery

Swyvl was built specifically for the problem that Dropbox and WeTransfer leave unsolved: letting your client actually see the data you are delivering, in their browser, without installing anything.

What Swyvl does well

• Browser viewing for every spatial format: LAS/LAZ point clouds load in a Potree viewer. GeoTIFF orthomosaics render on a Leaflet map. 3D models (GLB/OBJ) open in a Three.js viewer. E57 scan data is converted and viewable. PDFs, videos, 360 panoramas, DXF drawings — all viewable in the browser.
• Branded share links: Your client receives a link with your company name, your logo, and your brand colours. The experience says “your surveyor delivered this,” not “some file-sharing service.”
• Site and session organisation: Files are organised by physical site and capture session. Your client sees a clear timeline: “March 2026 survey,” “June 2026 follow-up.” Not a flat list of filenames.
• Audit trail: Every view, download, and interaction is logged with timestamp, IP address, and geolocation. You have a complete record of what was delivered, when it was accessed, and by whom.
• Permanent links: Share links do not expire. A client can access their survey data months or years later from the same URL.
• Download always available: Clients can still download the raw files if they need them. Viewing and downloading are not mutually exclusive.

Where Swyvl is more focused

• Not a general file sync tool: Swyvl is not a replacement for Dropbox as a general cloud storage platform. It is purpose-built for spatial data delivery.
• Not free for hobbyists: Swyvl is a professional tool with professional pricing. If you are sending one file to a friend, WeTransfer is fine.

Feature comparison table

The real comparison: what does your client experience?

Dropbox delivery experience

1. Client receives email: “Alex shared a folder with you on Dropbox”
2. Client clicks link, sees Dropbox interface with folder of files
3. Client sees filenames: site_pointcloud.laz, orthomosaic.tif, report.pdf
4. Client can preview the PDF. Everything else is just a download button.
5. Client downloads the LAZ file. Cannot open it. Emails you asking what software they need.

WeTransfer delivery experience

1. Client receives email: “Alex sent you files via WeTransfer”
2. Client clicks “Download,” receives a ZIP
3. Client unzips, sees the same list of files they cannot open
4. Client emails you. You explain CloudCompare. They do not install it.

Swyvl delivery experience

1. Client receives a branded link: “Your survey data from [Your Company]”
2. Client clicks link, sees your logo and a clean interface
3. Client sees sessions organised by date: “March 2026 Survey”
4. Client clicks on the point cloud — it loads in the browser, fully interactive
5. Client clicks on the orthomosaic — it renders on a map
6. Client rotates, zooms, explores. Downloads the raw files if they want them.

The difference is not subtle. In scenario one and two, the delivery is incomplete — the client has files but no way to use them. In scenario three, the delivery is complete — the client can see, explore, and download.

When to use each platform

Use Dropbox if you are already embedded in a Dropbox workflow with your client, the deliverables are formats they can open (PDFs, spreadsheets, images), and you need ongoing file sync rather than one-time delivery.

Use WeTransfer if you need to send a file to someone once, quickly, and you do not care about the long-term experience. Sending a quick reference photo to a colleague. Sharing a draft PDF for review. Transactional, ephemeral transfers.

Use Swyvl if you are delivering spatial data — point clouds, orthomosaics, 3D models, scan data — to a client who needs to see and interact with the data. If your deliverables include any format that requires specialist software, Swyvl solves the viewing problem that Dropbox and WeTransfer ignore.

The viewing gap is the real issue

The file transfer problem was solved years ago. Dropbox, WeTransfer, Google Drive, OneDrive — all of them can move large files from point A to point B reliably.

The viewing problem is what remains unsolved for survey professionals. And it is the viewing problem that determines whether your client actually engages with the data you delivered, or whether your carefully processed point cloud sits unopened in their Downloads folder.

If you are evaluating platforms for delivering drone survey data to clients, the question is not “which platform transfers files best?” — it is “which platform lets my client actually use what I deliver?”

That is the question Swyvl was built to answer.
