Can you upload to Dropbox without an account?
Yes, through a File Request. Dropbox's own help says you can't upload files to Dropbox without an account, with one exception: a File Request. The owner of the Dropbox creates the request and sends you a link; you open it, pick your files, and they land in a folder of theirs. No sign-up on your side.
Everything else people try first needs an account. A shared folder invitation asks you to sign in before you can add anything, and a shared link only lets you view and download. So if you don't use Dropbox, ask the owner for a File Request, not for folder access.
How to upload to a File Request (for the sender)
- Open the link the owner sent you, in any browser. On a phone this works too, no Dropbox app needed.
- Choose the files, then enter your name and email address when the form asks for them.
- Upload. Once the files are in, you can't open, rename or delete them from your side; they belong to the owner's folder now.
If the upload stops with an error, the most likely cause is not on your side: the owner's Dropbox is out of space, or a file is over their plan's size limit (2 GB on the free plan). Tell them; there is nothing you can retry that will fix it.
If you both have Dropbox: a shared folder
When the sender does have an account, the owner can share a folder with them as Can edit instead. The sender accepts the invitation and drops files into the folder like any other.
The catch is storage. A shared folder counts against the space of every member, so a sender on the free 2 GB plan can't add a 3 GB folder of photos, even if the owner has terabytes to spare. For one-way delivery a File Request is simpler: the files count against the owner's space only, and the sender never has to join anything.
How to create a Dropbox File Request (for the owner)
File Requests are available on every Dropbox plan, including the free Basic one. On dropbox.com:
- Select File requests in the left sidebar, then New request.
- Give it a Title your sender will recognize ("Signed lease - 14 Elm St" beats "Files"). The Description is optional; use it to say what you need.
- Under Folder for uploaded files, keep the suggested folder or pick another one. Set naming conventions can rename incoming files to a pattern, which helps once more than one person uploads. Senders only get an upload form, not access to the folder.
- Optional: a password (you have to pass it on yourself) and, on Professional and business plans only, a deadline.
- Select Create, then either enter the senders' email addresses or copy the link and send it however you like.
Dropbox emails you each time a file arrives. That is the whole feature, and for "send me the contract" between two people it is all you need.
If the sender has already been invited to a shared folder and is stuck on the sign-up screen, don't walk them through creating an account. Send a File Request pointing at that same folder: you get the files where you wanted them, and they never see a login screen.
Where a File Request breaks
None of these are bugs. The request is a door into your Dropbox, so it inherits your account's limits.
- Your storage is the ceiling. Every upload counts against your quota, 2 GB in total on the free plan. When it's full, the error shows on the sender's screen and nothing reaches yours: no file, so no notification either.
- Per-file size depends on your plan. 2 GB per file on Basic, Plus and Family; 250 GB on Professional and business plans.
- Deadlines need a Professional or business plan. On Basic, Plus and Family a request stays open until you close it by hand, and nothing reminds the sender.
- It is one folder, not a list. The description can say what you need, but the request can't tell you which of those files have arrived. You check the folder and chase the rest yourself.
And the obvious one: the request needs a Dropbox account on the receiving end. If the person you are sending to doesn't use Dropbox at all, there is no Dropbox route; ask how they want to receive files instead.
Before sending a request to someone with large files, check how much space you have left in your Dropbox account settings. Clearing room after a sender has already given up costs you a second round of emails.
When the request isn't enough: collect first, deliver to Dropbox after
The quota problem has a structural fix: let the upload land somewhere that does not depend on your Dropbox, then copy it in. 500files works this way. You make an upload page, senders add files to it without an account, and the files are kept on the page. If you sign in (with Google) and connect Dropbox from the page's dashboard, each file is also copied into Apps/500files/<page title> (<code>) in your Dropbox once it has passed the virus scan (and your approval, if you moderate uploads). The delivery guide covers the Dropbox details.
How this changes the picture:
- A full Dropbox no longer blocks the sender. The copies still count against your quota, so 2 GB is still 2 GB. But the upload has already succeeded on the page; if the copy fails, the file stays downloadable there and the dashboard marks it "Dropbox delivery failed", with the reason on hover.
- The page closes on its own. It is open for 7 days by default, can be extended to 14 days in total, and keeps the files downloadable for 3 more days after that. The copies in Dropbox stay.
- A checklist instead of a folder. You list what you need ("Signed lease", "Proof of insurance") and the dashboard shows what has come in and what hasn't.
- Large files upload in parts. Anything over 5 MB goes up in chunks; if the connection drops, adding the same file again continues from the last part received instead of starting over.
The trade-off runs the other way on file size: a page takes files up to 100 MB by default and 200 MB at most, well under the 2 GB a free Dropbox request accepts. And the app only ever sees its own Apps/500files folder, so it cannot put files into a folder you already share with your team; you move them there yourself.
Sort by sender before the files reach Dropbox. Make one upload page per client and each client gets their own folder under Apps/500files, named after the page title, with no renaming afterwards.
When you don't need anything else
- One sender, a few files, room to spare. Use the File Request. It is free, already in your account, and the sender never sees a login.
- Files over 200 MB. A File Request on any plan takes bigger single files (2 GB on free) than an upload page does.
- Permanent intake into a shared team folder. A request can point at a shared folder and stay open for months; upload pages are temporary by design.

The short version
Senders never need a Dropbox account, as long as the owner sends them a File Request; a shared folder works only when both sides have one. Owners: use the request when your Dropbox has room and the job is small. When the job is bigger than your free quota, or you need to know what is still missing, collect on a page and let it deliver into Dropbox: create an upload page on 500files, free, with no account needed for the people sending.
