Compressing Portrait Photos for Online Forms
Faces are where viewers notice compression first. Web forms often reject attachments above a set size, and the error message is not always clear about why.
Recommended settings for online forms
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1000 px on the long edge |
| Quality | 70 |
| File size | 100 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Compressing Portrait Photos
Smooth skin and soft backgrounds can show banding at low quality. Quality around 70 to 85 keeps tones natural.
Crop to head and shoulders when the image is shown small, as it often is for online forms. A tight crop lets you use fewer pixels without losing detail where it matters.
