What WhatsApp does to your image
WhatsApp re-compresses images when you send them as a photo, and the result is often noticeably soft — particularly for large images with fine detail. The more you make it compress, the worse the output, because its encoder is working on a file that has already been through one lossy pass.
Higher-resolution sends happen when you use the document attachment option rather than the photo option, which bypasses most of the re-compression at the cost of the recipient seeing a file rather than a picture.
Getting a better result
- Resize to around 1600 pixels on the long edge before sending — WhatsApp targets roughly that scale anyway, so pre-resizing on your terms looks better than letting it happen on theirs.
- Compress lightly (quality 85 or so) rather than heavily. A heavily compressed image that WhatsApp then compresses again looks much worse than a lightly compressed one.
- For anything where quality matters — a document, an ID, a design proof — send it as a document attachment, or send a link.
- Strip location metadata if you would rather not share where the photo was taken.
Status and profile pictures
Status updates and profile photos are cropped and scaled aggressively, typically to a square. A square source image, resized to about 1000 × 1000 pixels before uploading, avoids the awkward cropping that happens when a wide photo is forced into a square frame.
常见问题
WhatsApp 反正也会压缩图片吗？
是的 — WhatsApp 会压缩它发送的大多数照片。自行预先压缩让您可以控制质量，并减少进一步的画质损失。
WhatsApp 的合适大小是多少？
低于 1MB 就可以。更小的文件上传更快，也更不容易被进一步压缩。
这是私密的吗？
