Compress a Photo for WhatsApp Without Losing Quality

WhatsApp compresses whatever you send. Compressing it yourself first means you choose what gets lost.

Send a photo on WhatsApp and it arrives noticeably softer than the one you sent. That is the app doing its own compression on the way through, tuned for speed and data cost rather than for how your picture looks. You cannot turn it off — but you can change what it has to work with.

Why your photo gets worse

WhatsApp resizes and re-compresses images to keep them small. Feeding it an 8 MB, 4000px original means an aggressive squeeze. Feeding it something already close to what it wants means much less to do, and much less damage.

Compress it yourself first

Resize to around 1600px on the long edge and compress to somewhere in the region of a few hundred kilobytes. That is comfortably sharp on any phone screen, and it is close enough to WhatsApp's target that its own pass takes far less out.

Or send it as a document

If the photo genuinely has to arrive untouched — a scan, a document photo, something being printed — attach it as a document rather than a photo. WhatsApp passes documents through without re-compressing, at the cost of no inline preview.
