What's new on WhatsApp Web in 2026 — PDFs, browser calls and what is still missing

On July 22, 2026, Meta announced that WhatsApp Web and the desktop app can now open PDFs right inside a chat, with highlighting and annotation powered by Adobe Acrobat. Six days later, on July 28, voice and video calls arrived in the browser, with nothing to install. Those are the year's two official upgrades for people who work at a computer. The one many were waiting for, transcribing voice notes on WhatsApp Web, is still missing as of September 24, 2026.

This article is part of our WhatsApp news series: what Meta ships, with dates and sources, kept apart from what is still in testing.

What did WhatsApp Web actually get in 2026?

Of the official announcements we checked from January to September, on the WhatsApp blog and in Meta's newsroom, only two explicitly mention the computer. The rest of the year brought general features, such as member tags in groups (January 7), polls with an end time and the @all mention (August 4), and username reservations (June 29). Those posts don't say which devices get each feature, so there is no guarantee they are in your browser.

In the July 22 announcement, PDFs shared the stage with signing up directly on an iPad, no phone needed, and a rebuilt CarPlay and Android Auto for hearing and answering messages on the car screen. For anyone who spends the day at a desk, the PDF part is what counts. Meta said all of these features were already rolling out.

How does opening and marking up a PDF on WhatsApp Web work?

You click a PDF that arrived in a chat and it opens right there, full screen, without downloading the file. Adobe's help center spells out what is free: freehand drawing, highlighting, underlining and striking through text, with no Adobe account and no subscription. Editing the document's text, formatting it or reorganizing pages requires signing in and a paid Acrobat plan.

There is a detail Meta's announcement leaves out. According to Adobe, the feature works on WhatsApp Web in Chrome or Edge and in the Windows app. The Mac app, phones and the WhatsApp Business API are not supported. Adobe says the feature is available worldwide; neither company names specific countries.

In practice, it ends a familiar back-and-forth: download the file, open it in another program, mark it up, save it and attach it again. Now the markup happens without leaving the chat.

Can you make calls from WhatsApp Web without installing anything?

Yes, since the July 28 announcement. The WhatsApp blog says WhatsApp Web now makes and receives voice and video calls, one-on-one and in groups, with screen sharing, reactions and a Calls tab with your history. Calls are end-to-end encrypted, with no time limit and no cost.

The same post added four extras. Call transfer moves a group call from your phone to your computer, or the other way, without dropping it. A waiting room holds people who join by link until the organizer lets them in. QuickHD promises high-definition video within the first few seconds, and noise suppression removes background sound. WhatsApp says these are rolling out gradually and will be available to everyone soon. If the button hasn't shown up for you yet, that is the reason.

What is in testing and hasn't arrived yet

Some of what tech sites report comes from WABetaInfo, which tracks test versions of the app. None of it is an official announcement. On April 13 the site saw WhatsApp Web testing chat themes with 49 color options. On September 7 it reported that WhatsApp is preparing calls for guests without an account, who join through a link in the browser once the host approves them. Neither has a date.

Does WhatsApp Web transcribe voice messages yet?

No. Voice message transcripts launched on November 21, 2024, with the text generated on the device itself, and WhatsApp's help page walks through the steps on a phone. On Android, it lists four languages: English, Portuguese, Spanish and Russian. On the Web, Windows and Mac tabs of the same help page, checked on September 24, 2026, the answer is different: the feature is only available on certain devices and may not be available to you yet.

This year's announcements didn't change that. None of them mentions transcribing, summarizing or searching audio on a computer. And WhatsApp search looks for text: what a client said in a three-minute voice note doesn't show up when you type a word into the search bar.

If you get one voice note a day, picking up the phone works. If you get thirty, spread across ten chats, the problem is volume, and later finding what was said. That is the gap ZapVox, a WhatsApp Web extension that transcribes, summarizes and translates voice notes, covers on the computer: new voice notes in the open chat turn into text on their own, the text becomes searchable and a long chat can be summarized over the last 24 hours.

What changes for people who serve clients on WhatsApp

An accountant who receives company bylaws or a bank statement as a PDF can now open it in the chat, highlight the figure that doesn't add up and send it back to the client without downloading anything. A lawyer does the same with a draft contract: underline the clause, strike the paragraph that goes, send it back. A school receiving enrollment documents checks each page right there. Mac users go without this for now, since Adobe only lists Chrome, Edge and the Windows app.

Browser calls change the routine for anyone who already kept WhatsApp Web open. A clinic's front desk takes a patient's video call on the same computer used to book the appointment. A salesperson walks through a proposal by sharing the screen, and an agency holds a quick client meeting without asking anyone to install software. When it's time to leave the desk, call transfer moves the group call to the phone.

Voice notes are what stays the same. The salesperson who comes back from lunch to twelve waiting voice notes still listens to them one by one on the computer, or reaches for the phone and its built-in transcription, one note at a time.

Where this stops

• The rollout is gradual. PDFs and web calling were announced as rolling out. As of September 24, 2026, they may not show up on your account yet, and the sources give no final date and name no countries.
• PDFs have limits. The free part is markup: highlight, underline, strike through and draw. Editing text requires a paid Acrobat plan, and Mac is left out. Adobe's help pages don't explain where the file is processed; with a sensitive document, ask before using it.
• Testing is not launching. Themes and guest calls exist only in beta versions, according to WABetaInfo. They may change or never ship.
• ZapVox is for computers only. It works with WhatsApp Web open in Chrome, Edge or Firefox, not in the phone app. The Free plan has a daily quota, and summarizing a whole chat is part of Starter, Pro and the free trial.
• The audio goes to the cloud. To become text, it is sent to a transcription service. And when the WhatsApp Web screen changes, the extension needs an update.
