Cloudflare Drop limits: file size, hosting time and usage rules
Cloudflare Drop lets you upload a static website folder or ZIP in the browser and get an instant live preview. The important limit is clear: anonymous previews last 1 hour. Some other limits, especially exact upload size, are still not publicly documented in a stable way.
Current known limits
Account required to start
No
You can begin by uploading a static folder or ZIP in the browser.
Temporary preview time
1 hour
The official changelog says the live preview stays available for 1 hour unless claimed.
Supported upload shape
Folder or ZIP
Static HTML, CSS, JavaScript, images, and fonts are the intended content types.
Published upload size limit
Not clearly documented
Treat third-party measurements as temporary observations until Cloudflare publishes a stable number.
Pricing
Free to try
Drop starts without an account. Long-term use depends on claiming the deployment into Cloudflare.
What Cloudflare Drop is
Cloudflare Drop is a browser-based static site deployment tool. You drag in a folder or ZIP containing static files, then Cloudflare generates a live preview URL. It is closest to a quick preview workflow, not a full Git-backed deployment pipeline.
How long a Drop site lasts
According to Cloudflare's July 8, 2026 changelog, an unclaimed Cloudflare Drop preview stays live for 1 hour. During that window you can test the site, share the URL, or claim the deployment to keep it.
What files you can upload
Cloudflare describes Drop as supporting a folder or ZIP file of static assets, including HTML, CSS, JavaScript, images, and fonts. Server-side code, databases, build steps, and environment variables are outside the basic drag-and-drop use case.
File size and upload limits
As of July 12, 2026, Cloudflare has not clearly published a dedicated Cloudflare Drop file size limit in the official changelog. If you see a number in a tutorial, treat it as a test result for that day rather than a permanent rule.
What happens when you claim a site
Claiming is the step that moves the temporary preview into your Cloudflare account so it can persist beyond the anonymous 1-hour preview. For production work, expect to manage the project from Cloudflare after claiming it.
Custom domains
Cloudflare Drop is useful for creating the first live URL quickly. For a stable custom domain, you should plan to claim the deployment and manage it through Cloudflare's normal site and DNS workflow rather than relying on the anonymous preview URL.
Is Cloudflare Drop right for this job?
A practical fit check for common static hosting scenarios.
NeedFitWhy
Show a static draft for the next hour
Good fit
The 1-hour anonymous preview is designed for quick testing and sharing.
Send a client review link that should not expire today
Use with care
Claim the deployment or use a dedicated preview service if the link must stay available.
Host a production marketing site
Not enough by itself
You will likely need a claimed project, domain setup, analytics, deployment history, and operational controls.
Upload a plain HTML/CSS/JS folder
Good fit
That is the core Drop workflow.
Run server code or a framework build
Poor fit
Drop is for already-built static assets, not server runtimes or CI builds.
Publish AI-generated HTML for review
Good fit
It works well when the AI output is static and ready to preview in a browser.
Security note
Instant static hosting is convenient, but it also means links can point to content you have never reviewed. Check who sent the link, inspect the domain carefully, and do not enter credentials on an unfamiliar static page. Cloudflare infrastructure and HTTPS do not guarantee that the page itself is legitimate.

FAQ
Is Cloudflare Drop free?
Cloudflare Drop lets you start without a Cloudflare account and create a temporary preview. Cloudflare describes Workers as free to try, but you should check your Cloudflare account plan and product limits before treating a claimed deployment as a long-term free production host.
How long does a Cloudflare Drop link last?
The official Cloudflare changelog says the temporary live preview stays live for 1 hour. To keep the deployment, claim it during that window.
What is the Cloudflare Drop file size limit?
As of July 12, 2026, a specific Drop upload size limit is not clearly documented in the official changelog. Avoid publishing a hard number unless Cloudflare documents it or you label it as your own test result.
Can Cloudflare Drop upload a ZIP?
Yes. Cloudflare says Drop supports uploading a folder or ZIP file of static assets such as HTML, CSS, JavaScript, images, and fonts.
Does Cloudflare Drop support custom domains?
The anonymous preview URL is for quick sharing. For a custom domain, claim the deployment into a Cloudflare account and use Cloudflare's normal domain and DNS setup.
Is Cloudflare Drop safe?
Cloudflare Drop can be safe as a deployment tool, but any public static hosting product can host untrusted content. A Cloudflare-branded domain or TLS lock does not prove the page content is trustworthy. Do not enter passwords or payment details on an unfamiliar Drop link.
Need a stable review link?
Cloudflare Drop is a strong quick-preview option. When you need to send AI-generated HTML or a static ZIP to reviewers without asking them to claim a deployment, HTMLShare creates a simple browser preview link for feedback.
