Understanding KB and MB When Preparing Images for Scanned Receipts
Size limits are written in kilobytes and megabytes, and the units trip people up. Expense tools mostly need receipts to be legible, not print quality, so small files work well.
Recommended settings for scanned receipts
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1200 px on the long edge |
| Quality | 70 |
| File size | 150 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
Understanding KB and MB When Preparing Images
One megabyte is roughly 1000 kilobytes, and some systems count 1024. If a limit says 100 KB, aim a little under, such as 95 KB, to be safe.
For scanned receipts, a target of 150 KB is a comfortable default. Our results panel shows the exact size of each compressed file so you can confirm it before uploading.
