How to Resize Images for Scanned Receipts
Resizing is the single biggest lever for file size. 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.
How to Resize Images
File size scales roughly with the number of pixels. Shrinking a 4000 by 3000 photo to 1200 pixels wide removes most of the data before compression even begins.
Keep the aspect ratio locked so nothing looks stretched. Our compressor scales proportionally when you set a maximum width, so you only need to enter one number: 1200.
Step by step with TheCompressJPEG
- Open the compress JPEG to 150 KB tool, or the main compressor for custom settings.
- Drop in your image. Nothing is uploaded; it is processed in your browser.
- Set the maximum width to 1200 and the target size to 150 KB.
- Press Compress, check the result and download it.
Quick tips
- Write a size limit slightly below the stated maximum to leave a margin.
- Process private images locally rather than uploading them to unknown servers.
- Crop out distractions so pixels go to the subject.
- Use WebP where it is supported and you control the page.
