Limits
What a link can hold, who can open it and how long it lasts.
Visibility
| Setting | Who can open the link |
|---|---|
| Public (the default) | Anyone with the link. |
| Password | Anyone with the link who also knows the visitor password. |
A random address is not private. Anyone who is sent the link, or finds it, can open a public link.
A visitor password is 8 to 256 characters. After entering it, a visitor stays unlocked for 12 hours in that browser. Changing or removing the password signs out everyone who had unlocked the link. Password-protected pages are not cached and cannot be read by other websites.
Ask the person you are publishing for which setting they want before you publish. The CLI and API publish publicly unless you set a password.
Expiry and deletion
| What happens | |
|---|---|
| Guest link | Expires 24 hours after it was created. Publishing an update does not extend it. After expiry it stops working and cannot be claimed. |
| Link in an account | Does not expire. It stays until you delete it. |
| Claiming a guest link | Moves it into your account at the same address and removes the expiry. |
| Deleting a link | Stops serving it straight away. Its files are cleaned up afterwards. The name is never given out again. |
| Pruning a version | Removes one version that is not live. The live version cannot be pruned. |
Files and sizes
| Limit | Value |
|---|---|
| One file | 25 MiB (26,214,400 bytes) |
| One publication (all files in one version) | 100 MiB (104,857,600 bytes) |
| Files in one publication | 500 |
| One guest publication | 25 MiB (26,214,400 bytes) |
| Storage for one account: the live and staged versions of all its links | 1 GiB (1,073,741,824 bytes) |
| Links in one account | 100 |
| Versions kept per link | 100 |
| File path length | 512 bytes |
| Title | 120 characters |
| Link name | 3 to 48 lower-case letters, numbers and inner hyphens |
ZIP files count by their unpacked contents: a ZIP that expands past the file, size or storage limits is refused. ZIPs cannot contain other ZIP, 7z or tar archives, and password-protected ZIPs are refused.
Versions that are staged but not yet finalised count towards storage, so an unfinished upload still takes space until it is published or pruned. Unfinished versions are dropped after 24 hours, and a new link that was never finalised is removed after 24 hours too.
DropZoom only serves static files. It does not run server code, so uploaded scripts run only in the visitor's browser. Some names are reserved for DropZoom and cannot be used for a link.
Uploads
| Value | |
|---|---|
| Upload URLs stay valid for | 1 hour |
| A staged version can be refreshed for | 24 hours after it was created |
Feedback
| Limit | Value |
|---|---|
| Feedback text | 2,000 characters |
| Reviewer name | 60 characters |
| Open feedback items per link | 50 (resolve some to accept more) |
| Feedback items per resolve call | 90 |
| Feedback items per page when listing | 1 to 200 |
Rate limits
Limits are counted per IP address, per minute. Going over returns 429 rate_limited; wait a minute and retry.
| What | Limit |
|---|---|
| API requests to the publishing service | 1,200 per minute |
| Creating new links | 10 per minute |
| Password attempts on one link | 10 per minute |
| Feedback submissions on one link | 10 per minute |
Updating an existing link, uploading and finalising count only towards the general API limit.
