Lectra Receiver is a free Chrome extension that moves PDFs between your browser and Lectra on your iPad. Use it to send a reading from a browser tab to your iPad, to download a marked-up document you send back from Lectra, and to attach a Lectra PDF to a Gradescope submission without saving it first.
Two Scope apps carry the name Lectra Receiver. This page covers the Chrome extension, which you get from the Chrome Web Store. The app you install on a Mac also shows up as Lectra Receiver in your menu bar, and the canvascope.org/receiver page is about that Mac app. To learn about it, see Lectra for Mac.
If you already use the Scope extension for Chrome, it can send course files to your iPad too. To learn how, see Send files from Chrome to your iPad. Lectra Receiver is a smaller extension that does only the PDF handoff. If you install both, Lectra Receiver’s Send to Lectra and Select from Lectra buttons take the place of the Scope extension’s, so you see one of each.

​
Before you begin

  • Chrome on a computer.
  • Lectra on your iPad, signed in to your account. To learn about accounts, see Your Scope account.
  • A Google account. Lectra Receiver signs in with Google only. Use the same Google account that you use for Lectra on your iPad, so both apps reach the same library.

​
Install Lectra Receiver

1

Add the extension

Open Lectra Receiver in the Chrome Web Store, and then click Add to Chrome. When Chrome asks, click Add extension. The listing names the publisher as Canvascope, the former name of Scope.
2

Pin it to the toolbar

In the Chrome toolbar, click Extensions (the puzzle piece), and then click the pin next to Lectra Receiver. Pinning keeps the icon in reach.
3

Sign in

Click the Lectra Receiver icon, and then click Sign in with Google. Choose the Google account that you use for Lectra. When you’re signed in, the panel shows “Signed in as” followed by your email address.
4

Check that Lectra tools are on

In the same panel, make sure the Lectra tools switch is on. It’s on when you install the extension. While it’s on, the Send to Lectra button appears on PDFs and the extension stays ready to receive files.
The Receiver card at the bottom of the panel shows whether the extension is ready. A green dot means it’s ready. An orange dot means it needs your attention, for example because you’re signed out or Lectra tools are off. A red dot means something went wrong.

​
Send a PDF to your iPad

1

Open the PDF in Chrome

Open any PDF in a Chrome tab, such as a reading on your course site. A floating Send to Lectra button appears on the page.
2

Click Send to Lectra

The button changes to Sending… and then to Sent ✓.
3

Open it on your iPad

In Lectra, the file arrives in the Scope Inbox in your library. If Lectra is open, a message says that the file arrived, with an Open button.
If the button covers something on the page, press and hold it, and then drag it somewhere else. Lectra Receiver remembers where you put it.

​
Send a PDF saved on your computer

Chrome blocks extensions from reading files on your computer until you allow it. To send a PDF that you opened from your computer:
1

Open the extension's details

In Chrome, go to chrome://extensions, find Lectra Receiver, and then click Details.
2

Allow file access

Turn on Allow access to file URLs.
3

Send the PDF

Reload the PDF tab, and then click Send to Lectra.
Lectra Receiver sends PDFs only, up to 25 MB each.

​
Receive a document from your iPad

When you send a document from Lectra on your iPad to your computer, Lectra Receiver downloads it in Chrome to your usual downloads folder.
1

Keep Chrome ready

On your computer, keep Chrome open with Lectra Receiver signed in and Lectra tools on.
2

Send from Lectra

On your iPad, open the document in Lectra. Tap the document’s name at the top of the screen, and then tap Export to Scope.
3

Choose your browser, if Lectra asks

If you have more than one place to send to, Lectra shows a Send to list. Lectra Receiver appears with the name of your browser and computer, such as Chrome + macOS. Tap it.
4

Find the download

Lectra shows “Sending to” followed by the destination name, and then “Sent to” when the upload finishes. A moment later, the PDF downloads to your Downloads folder, with your markup on the pages. Chrome doesn’t show a separate notification, so look in Chrome’s download list or your Downloads folder.
If Chrome is closed when you send, the document waits. It downloads the next time Chrome opens with Lectra Receiver running. To learn about every way to move files, see Send files between devices.

​
Attach a Lectra PDF on Gradescope

Lectra Receiver adds a Select from Lectra button to Gradescope upload forms, so you can submit a document from your Lectra library directly.
1

Open the upload form

In Gradescope, open the assignment and start a submission. Next to Gradescope’s Select PDF button, a Select from Lectra button appears.
2

Choose a document

Click Select from Lectra. A list of your Lectra documents opens. To find one, type in Search your Lectra documents…, and then click the document.
3

Submit

The button changes to show the document’s name followed by “ready”. Finish the submission in Gradescope as usual.
In the list, a document marked Annotated has a backed-up copy that includes your markup. A document marked Open on iPad is the one open in Lectra on your iPad right now.
The list shows only documents that Lectra has backed up from your iPad. Lectra Receiver attaches the most recent backed-up copy of your pages, or the original PDF if no marked-up copy exists yet. If you wrote on a document recently, give Lectra time to back it up before you attach it. To learn how backups work, see Backups.

​
Sign out or turn it off

  • To pause the extension, click the Lectra Receiver icon and turn off Lectra tools. The Send to Lectra button disappears, the Select from Lectra button disappears from Gradescope, and the extension stops receiving files.
  • To sign out, click the Lectra Receiver icon, and then click Sign out.
  • To remove it, right-click the Lectra Receiver icon, and then click Remove from Chrome.

​
Troubleshooting

Click the Lectra Receiver icon and check that you’re signed in and that Lectra tools is on. If the PDF is a file on your computer, turn on Allow access to file URLs as described in Send a PDF saved on your computer. Then reload the tab.
Lectra Receiver couldn’t find a PDF in the tab. Open the PDF itself, so the tab shows only the document, and then try again.
The site didn’t let the extension download the file from this page. Open the PDF in its own tab, and then click Send to Lectra again.
Lectra Receiver sends PDFs up to 25 MB. For a larger file, download it and import it into Lectra on your iPad instead. To learn how, see Import documents.
Click the Lectra Receiver icon, and then click Sign in with Google.
Make sure Lectra on your iPad is signed in to the same account as Lectra Receiver. Open Lectra and check the Scope Inbox in your library.
Check that Chrome is open, that Lectra Receiver is signed in to the same account as your iPad, and that Lectra tools is on. The document downloads when the extension is ready.
The list shows only documents that Lectra has backed up. Sign in to Lectra on your iPad with the same account, and give it time to back up. To learn more, see Backups.
