Compressing Product Photos for Signature Uploads
Product photos must look accurate because people judge the item by them. Signature images are simple black-on-white marks, so they can be very small while staying perfectly legible.
Recommended settings for signature uploads
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 300 px on the long edge |
| Quality | 60 |
| File size | 20 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Compressing Product Photos
Shoot on a clean background, crop tightly, and resize to about 300 pixels. Clean backgrounds compress extremely well.
Check colour and texture after compressing. For signature uploads, a slightly larger file that shows the product clearly beats a tiny one that hides detail.

Wrapping up
For signature uploads, the reliable recipe is simple: resize to around 300 pixels, compress at quality 60 or to a 20 KB target, and check the result before you upload. Keep the original so you can always start again.
