After a month of testing, WhatsApp switched on three changes for everyone in the first week of May 2022. Files of up to 2 GB can now be sent in a chat, up from a 100 MB limit that dated from the app's early days; messages can be answered with an emoji reaction instead of a reply; and groups can grow to 512 members, double the previous 256.
2 GB files: what it is for
The new limit means a full-length video, a folder of RAW photos zipped up, or a PDF scan of an entire land record can go through WhatsApp end-to-end encrypted, without a Google Drive link. Files are sent as documents, so nothing is compressed. WhatsApp suggests using Wi-Fi for large transfers, and in Bangladesh that is not a suggestion but a warning: a 2 GB file sent over a mobile pack that costs Tk 20 per GB is Tk 40 each way, and the receiver pays too. On Android, turn off auto-download for documents on mobile data (Settings, Storage and data, Media auto-download) so a colleague's 1.5 GB video does not eat your pack while you sleep.
Reactions
Long-press any message and pick one of six emoji: thumbs up, heart, laughing, surprised, crying or folded hands. Reactions are the quiet answer to a problem every Bangladeshi family group has, where a single photo of a wedding produces forty "wow" replies and forty notifications. A reaction shows under the message and, by default, sends only a muted notification. The feature reached a subset of users first and everyone within a week, on both Android and iOS. More emoji were promised later.
512-person groups
The larger cap is rolling out gradually. It matters for the way WhatsApp is actually used here: batch groups of an entire school year, union-level farmers' groups run by agricultural extension officers, and the neighbourhood groups that coordinated relief during the 2020 floods, all of which hit 256 regularly. Admins should remember that in a group this size the "only admins can send messages" setting is the difference between a notice board and noise.
All three features work inside WhatsApp's end-to-end encryption, which is the reason the Meta-owned app has become the default for anything sensitive. The changes come alongside the "Communities" structure Meta previewed in April, which groups related groups under one umbrella.
The limits that did not move
A 2 GB ceiling sounds like the end of the problem and is not, for two reasons that matter more here than in the markets where the feature was designed.
The first is upload speed. Sending a 2 GB file over a typical mobile connection in Bangladesh is a long, battery-draining operation that fails if the signal drops, and the sender pays for every megabyte twice if it has to restart. The second is storage: WhatsApp saves received media to the phone by default, so a 512-person group sharing large files will fill a 64 GB handset faster than its owner expects.
Two settings are worth changing once. Turn off automatic media download on mobile data, under Settings → Storage and data, and review Manage storage occasionally — it lists the largest files and the chats hoarding them.
