How to Compress Images for Online Forms on Android
Android phones can compress images right in the browser. 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.
How to Compress Images
Open Chrome, load TheCompressJPEG, and tap the file picker to choose images from your gallery or file manager.
