You can send audio, images, videos and documents straight from the Inbox to the contact. Each channel (WhatsApp Cloud API, WhatsApp Business and LinkedIn) has its own rules for type, size and format (knowing the limits prevents send failures and rejected messages).

Available on: All plans.

Who can do it: Any user with access to the Conversations module and permission to send messages.


Before you start

  • The conversation must be open. On WhatsApp, free-form sends (including media) are only possible while the 24-hour window is open; LinkedIn has no window.

  • Have the file available on your computer or phone, or already saved in the Media library.

  • Know which channel the conversation uses (WhatsApp Cloud API, WhatsApp Business or LinkedIn); size and format limits differ between them.


Attach straight from the Media library

Anything already saved in the Media library can be attached without uploading the file again.

  1. In the message box, click + or type /

  2. Choose Photos and videos or Attach document

  3. In the submenu, click Choose from media library (or Upload from device, to use a file from your computer)

  4. Select the items. You can choose up to 5 per send, and they go into the tray along with the ones from your computer

  5. Click Send

  • The library opens already filtered by type (photos and videos, or documents). Items in a format the channel doesn't accept appear disabled, with the reason

  • Deleting the item from the library later doesn't affect what was already sent

  • Audio from the library can't be sent in the conversation yet


Send an image

  1. Open the conversation from the side menu, in Conversations

  2. In the message box, click the Attach icon (paperclip)

  3. Select Image

  4. Choose the image (use JPG or PNG; sizes and formats per channel are in the limits table)

  5. Click Send

Paste an image straight into the conversation (Ctrl+V / Cmd+V)

You can paste an image from the clipboard straight into the message field, without using the attach button.

  1. Copy an image (a screenshot, or an image copied from another app or the browser).

  2. In the message field, press Ctrl+V (Windows/Linux) or Cmd+V (Mac).

  3. A confirmation modal opens with a preview of the image.

  4. Review it and click Send.


Send a document (PDF, DOCX, etc.)

  1. Open the conversation in Conversations.

  2. Click the Attach icon in the message box.

  3. Select Document.

  4. Choose the file (accepted formats vary by channel — see the limits table).

  5. The file's original name is kept and shown to the contact.

  6. Add an optional caption and click Send.


Send audio (voice message)

  1. Open the conversation in Conversations.

  2. In the message box, click the Microphone icon.

  3. Allow microphone access if it's your first time (browser popup).

  4. Start talking; the icon turns into a live recording indicator.

  5. Click Send to send the recording, or Cancel (trash icon) to discard it.

The audio is sent to the contact as a native WhatsApp voice note.


Download media from the conversation (audio, image, file and video)

Any media in the history — received from the contact, sent by you or sent by the AI agent — can be saved to your computer from the message menu, always in the same place.

  1. Hover over the message in the conversation history. A small arrow appears at the top of the bubble (for audio, it appears next to the player, in a space the bubble opens on the right).

  2. Click the arrow.

  3. Choose the download option shown: Download audio, Download image, Download file or Download video.

  4. The file is saved straight to your computer.

The menu only shows the option that makes sense for that message: an image shows Download image, a PDF shows Download file, and so on. For video, the menu is the only way to save the file — the video player has no download button.

Name the file is saved with

Media typeFile name
Audio Date and time the message appears in the conversation, in your time zone: audio-2026-09-08_15-30.ogg. The extension matches the audio's actual format (.ogg, .mp3, .m4a, .opus, .wav and others)
Image Original file name of the image (for example foto final.jpg)
File (document) Original name the sender used (for example Proposta comercial.pdf). When the sender doesn't include a name, the file is saved as documento. + the file's actual extension — an XLSX becomes documento.xlsx, not documento.pdf
Video Original name the sender used. Without a name, video. + the actual extension (video.mp4, for example)

What you see while the download happens

  • As soon as you click, a Downloading… notice appears in the corner of the screen.

  • When the file is saved, the notice disappears and the download shows in the browser bar, like on any other site.

  • If for some reason Nuvia can't save it directly, it opens the file in a new tab and lets you know: “Couldn't download directly. We opened the file in a new tab.” From there, you save it through the browser.


Send a video

  1. Open the conversation in Conversations.

  2. Click the Attach icon and select Image or Video.

  3. Choose the file; we recommend MP4 with H.264 codec and AAC audio.

  4. Add an optional caption and click Send.


View PDFs in the conversation

PDFs received or sent can be opened right in Conversations, without downloading.

  1. In the conversation history, find the message with the PDF document.

  2. Click the document card (the whole card is clickable).

  3. A modal opens with the PDF in full screen, in a viewer on the screen itself.

  4. Use Download PDF (top right corner of the modal) to save the file.

  5. Close the modal with Esc or by clicking outside it.


Receive media that arrives late (LinkedIn)

On LinkedIn, some videos and audio files sent by the contact arrive in two steps: first the message appears and, only a few seconds or minutes later, the file becomes available. Nuvia handles this automatically, with nothing for you to do.

  • Until the file arrives, the message shows “Loading media…” with a loading indicator in place of the media.

  • When the file becomes available, Nuvia downloads it and the message updates on its own (“Loading media…” is replaced by the actual video, audio or image, without reloading the page).

  • If the file doesn't become available after several attempts (Nuvia tries for about 1 hour), the message shows “Media unavailable”.

Frequently asked questions

Frequently asked questions

Can I send several media files at once in the same message?

You can select up to 5 files at once, from your computer or the Media library. Each attachment reaches the contact as a separate message in the history.

Do I need to upload a file that's already in the Media library again?

No. From + or /, choose Photos and videos or Attach document and click Choose from media library. The same goes for quick replies, template headers and the Google Calendar reminder.

Does sent media count against my plan?

Yes. Each message with media counts against your plan as a regular message, just like a text message.

Can I send media outside the 24-hour window?

On WhatsApp, not directly; outside the window, only with an HSM template. There are HSM templates with media (image, video or document in the header) that reopen the conversation with media. LinkedIn has no window, so sending is always allowed.

How do I send photos from my phone?

Open Nuvia in your phone's browser, open the conversation and click Attach; the browser opens the phone's photo picker. Alternatively, send the photo to yourself on WhatsApp and download it on your computer.

How do I save audio from the conversation to my computer?

Hover over the audio, click the arrow that appears next to the player and choose Download audio. It works for audio received from the contact, recorded by you or sent by the AI agent. The file is saved with the date and time in its name (for example audio-2026-09-08_15-30.ogg), in the audio's original format.

How do I save a video from the conversation?

From the arrow menu: hover over the video, click the arrow at the top of the bubble and choose Download video. That's the only way — the video player has no download button of its own.

Is there a limit on audio length?

The limit is by size (16 MB on WhatsApp), not by length. Under normal conditions, this allows audio of up to about 10–15 minutes. For long conversations, consider scheduling a meeting instead.

Is sent media stored in Nuvia?

Yes. The full conversation history, including files, is kept and can be checked at any time by opening the conversation.

Can I download media the contact sent me?

Yes, always in the original format, and the path is the same for everything: the arrow menu at the top of the bubble (Download audio, Download image, Download file or Download video). Images and documents also have their own shortcuts: images have Download image inside the full-screen view, and the document card has a download button. The card shows the file's real name (e.g. “Proposta comercial.pdf”), on both WhatsApp and LinkedIn, and the file is saved with that same name no matter where you click. A generic name only appears when the sender doesn't include a file name — in that case the extension still matches the file's actual type.

Do videos sent from the Inbox show up as native video in the contact's WhatsApp?

Yes, as long as the file is MP4 with the H.264 codec. Other formats may show up as a video document (they need to be downloaded to watch).

Can I send files in LinkedIn conversations?

Yes. Images, videos, PDFs and documents are accepted, with a limit of 15 MB per file. Audio isn't supported yet; if you try, you'll see the warning “Audio not supported on LinkedIn yet. Send text, an image, a PDF or a video.”

Do files the contact sends on LinkedIn show up in the Inbox?

Yes. The file is downloaded automatically and becomes available in the conversation history and in the Files section of the side panel. In some cases, the video or audio arrives seconds or minutes after the message; during that time you'll see “Loading media…”, and the message updates on its own when the file arrives.

Why did “Media unavailable” appear on a message?

This happens when a LinkedIn video or audio didn't become available even after Nuvia tried to download it for about 1 hour. The message was received, but the file couldn't be retrieved. Ask the contact to send it again if needed.
