Attach tickets and documents

Attachments are the files your trip runs on: the e-ticket PDF, the hotel confirmation, the insurance certificate, a photo of the parking permit. Members with active Limbo Pro can open files shared with the trip, so nobody has to dig through a mailbox at the airport.

Where attachments live

There are two places to put a file, and it is worth choosing the right one.

• On the trip. Open the trip workspace, scroll the top pill row just past Balances, and tap Attachments. Use this for anything that covers the whole trip: insurance, a visa letter, or the group's itinerary PDF.
• On a plan. Open a plan from the timeline or the map to see its saved files. To add a file to that plan, tap the pencil and scroll to Attachments at the bottom of its edit form. Use this for the file that belongs to that booking: the flight's e-ticket, the hotel confirmation, or the tour voucher.

The trip workspace shows All, Photos, and Files filters above a two-column gallery. Every card includes the file type, name, and size. Plan details retain the compact file list. The trip workspace includes Add photo and Add document for trip-wide files; the plan edit form provides the same controls for that plan. Both editors show storage meters and a file count. When nothing matches the selected filter, Limbo shows the relevant empty state.

What you can attach

Limbo accepts PDF, JPEG, PNG, and HEIC files. The limits shown in the app are 15 MB per file, 250 MB per trip, and 2 GB per account. Those are exact binary limits: 15 MiB, 250 MiB, and 2 GiB.

There is no separate limit on the number of attachments. The 250 MB trip allowance includes files on the trip and every plan in it. Your 2 GB account allowance covers files you upload across all trips, plus files you choose to keep when confirming a plan from email. Files another crew member adds count toward that member's account allowance, while still sharing the trip allowance. Limbo compresses selected photos before uploading when possible.

A few things worth knowing before you pick a file:

• You attach one file at a time. Add the next one when the first has finished.
• Limbo inspects the file itself, not just its name, so renaming something to .pdf will not get it through. An unsupported file gets a short Unsupported attachment message.
• A file over the limit is refused with Attachment too large. Export a lighter PDF or a smaller photo and try again.
• Trip storage and Account storage meters show how much room is left. If either is full, delete an attachment charged to that allowance before uploading another.

Add a photo

1. 1
   Open Attachments from the trip's top workspace pills to add a trip-wide file. For a plan-specific file, open the plan, tap the pencil, and scroll to Attachments in its edit form.
2. 2
   Tap Add photo.
3. 3
   On mobile, allow photo access the first time you are asked. In the web app, your browser opens its file picker instead.
4. 4
   Pick one image. It uploads straight away and appears in the list.

Add a document

1. 1
   Open the trip's Attachments workspace, or open a plan, tap the pencil, and scroll to its Attachments section. Then tap Add document.
2. 2
   Your device's file picker opens, filtered to the file types Limbo accepts.
3. 3
   Choose the file. It uploads and joins the list underneath. If uploading fails, your existing files stay in place; choose Add document again and select the file to retry.

Each gallery card or list row shows the file's name and size with an image or PDF icon. A spinner appears while Limbo is opening or removing that file.

For a free editor, upload controls stay visible in grey with a lock; every free crew member sees the same locked treatment when opening an existing file. Tap a locked control or file to view Limbo Pro. Existing file names and sizes remain visible, and Limbo does not delete stored files because Pro ends.

Open an attachment

Tap the gallery card or list row.

• Images open in a preview inside the section. Tap the preview to close it again. With a keyboard, focus Close image preview and press Space or Enter.
• Documents on mobile hand off to whatever your phone uses to read them, usually your browser or a file viewer.
• PDFs on the web open inside Limbo. Use the previous/next-page and zoom controls, Download PDF to save a copy, or Close document preview to return to the gallery. These controls work with Space or Enter. If a PDF cannot be displayed, you can still download it for another reader.

While online, Limbo fetches a fresh link that expires after five minutes every time you tap, so come back to the trip or the plan to open the file again rather than keeping the old link around. While offline, an image or document can open from a ready offline travel pack instead.

Files opened from a plan's details or Incoming Plans may open in a new browser tab. If the browser blocks it, choose Open file to try again, or Cancel to stay in Limbo. If it is still blocked, allow pop-ups for Limbo and tap the attachment again. Keep the plan or Incoming Plans open while the file loads; leaving that view cancels the pending opening.

Privacy and connectivity

Attachment content is stored privately and encrypted at rest. It is not given a public file address: an authorized member with active Pro requests a short-lived link when they open it. File names and sizes remain visible to the trip's crew, so only attach something you are comfortable sharing with everyone on that trip.

Uploading and deleting attachments always needs an internet connection. Opening normally needs one too, unless the file finished downloading into that trip's ready offline travel pack. The downloaded copy uses a random device-only key held in iOS Keychain or Android Keystore and can open only for the same signed-in account and Limbo environment while its secure Pro verification remains valid. Routine same-account session refreshes and sign-in-token rotations do not invalidate it; signing out or switching accounts removes the key and downloaded files.

Keep attachments available offline

When Offline travel packs is enabled for your build, connect, open Account → Offline travel packs, then download or refresh the trip. The pack includes every current trip and plan attachment that fits the same limits above; it does not download Google Maps tiles.

If a download stops, its verified progress remains available and Resume download continues it. Refresh before travelling so attachments added or changed since the last download are included. Offline authorization ends at the earlier of your Pro subscription expiry and 72 hours after Limbo last verified Pro online. If that happens, the encrypted files stay on the device but remain closed until you reconnect and refresh the pack.

Removing a pack deletes only its device copies. Deleting an attachment from the shared trip is a separate online action and removes it for the whole crew.

Delete an attachment

A small red bin sits in the card or at the end of a row when you are allowed to remove that file. You see it if you uploaded the file yourself, or if you are the trip owner. owner

Tapping it asks you to confirm, and the message is honest about the reach: the file "will be removed for the whole crew." There is no undo, and deleting the file does not touch the plan or the trip it was attached to. Authorized deletion remains available without Pro so a subscription never prevents data cleanup.

Deleting the whole trip clears its stored files too, along with the files on its plans. See Archive, reactivate, and delete a trip.

Files from a forwarded booking email

When you forward a booking confirmation to Limbo and confirm the plan it found, the Keep original email & files switch decides whether the attachments from that email are saved onto the new plan. Leave it off when the files carry passenger or payment details you would rather not share with the crew.

When Limbo saves a new email file, it is charged to the account that confirms the plan. That member or the trip owner can remove it later. owner More on the whole flow in Plans from your email.
