Dropbox Link Shortener

Yes. Flyn redirects to the exact URL you paste, including the rlkey query parameter that authorizes access to a shared Dropbox file or folder. Because the full token travels through the redirect untouched, recipients land on the file with the same access they'd get from the raw Dropbox link.

Yes. Dropbox uses dl=0 to open a file in its in-browser preview and dl=1 to trigger an immediate download. Flyn preserves whichever value you paste, so a flyn.to link built from a dl=1 URL still downloads instantly and a dl=0 link still opens the preview, the parameter is part of the destination, not something Flyn strips or rewrites.

No. Flyn only issues a standard 301/302 redirect to your Dropbox URL, it never proxies, re-hosts, or touches the file. Dropbox alone decides who can view or download based on your share settings and the rlkey, so wrapping the link in flyn.to changes nothing about access control.

Yes. Flyn records every click in real time with country, device, browser, and referrer breakdowns, all on the free plan. This is invaluable when you send a proposal, portfolio, or media kit and want to know whether the prospect actually opened it (and from where) before you follow up.

It depends on how you update it. If you upload a new version while keeping the same Dropbox file (so the share URL and rlkey stay the same), your Flyn link keeps working with zero changes. If you delete the file and upload a fresh one, which generates a new URL, just edit the Flyn link's destination once and every previously shared short link points to the new file.

Yes. Flyn never downloads or stores the file, it redirects to Dropbox, which serves the content directly, so file size is irrelevant to the short link. Whether you're sharing a 2 KB text file or a 20 GB video master, the flyn.to link behaves identically and Dropbox handles the actual transfer.

Yes. Flyn Pro supports up to 3 custom branded domains, so your Dropbox deliverables can go out on links like assets.youragency.com/final instead of flyn.to. Branded links look more trustworthy on invoices and statements of work and reinforce your studio or agency identity at the moment a client clicks.

Yes. Every Flyn short link has an editable destination. Repoint flyn.to/proposal from version one of a PDF to the signed-off final, or swap a single-file link for a whole folder, without changing the URL you already emailed, printed, or pasted into a contract.

Yes, every Flyn short link includes a built-in QR code generator. Designers and agencies use this to put a scannable link to a digital portfolio, lookbook, or asset folder on printed business cards, leave-behinds, trade-show handouts, and packaging, then repoint the destination later without reprinting.

Yes. Paper docs (paper.dropbox.com) and Dropbox Transfer links shorten and track exactly like standard file and folder URLs. Note that Dropbox Transfer links are designed to expire on a schedule you set, so once a Transfer expires the underlying file is gone, the Flyn link will faithfully redirect to Dropbox's expired-transfer page, at which point you can repoint it to a fresh Transfer.

Yes. Flyn lets you layer its own password protection and link-expiry date on the short link itself, which is handy on plans where Dropbox's native password and expiry controls aren't available. Visitors must enter your Flyn password (or arrive before the expiry) before the redirect fires, giving you an extra gate in front of the Dropbox file without upgrading your Dropbox tier.

Yes. Team and Dropbox Business shared links use the same scl/fi and scl/fo URL structure with an rlkey, so Flyn shortens and tracks them the same way. Access is still governed entirely by your team's Dropbox settings and member permissions, Flyn just provides the clean, trackable wrapper around whatever link your team policy allows you to create.

No, and you shouldn't treat it as one. A flyn.to slug hides the file ID and rlkey from casual view, but anyone who obtains the short link can still follow it, so obscurity is not security. For genuinely sensitive files, rely on Dropbox's real controls (restrict to specific people, set view-only, add a Dropbox password and expiry), and use Flyn's password protection and analytics as an extra layer on top, not as your only line of defense.

No. Flyn is a full URL shortener that works with any link: Dropbox, your own website, YouTube, Etsy, affiliate links, PDFs, anything with a URL. This page just shows the Dropbox use case. Every feature here (click analytics, editable destinations, branded domains, QR codes) applies to every link you shorten.
