# `INVALID_FILE` File cannot be read

Source: https://checkslip.com/en/problems/invalid-file

- **HTTP status**: `422`
- **Credit**: No credit taken

## Meaning

The file is empty, broken, over 50 megapixels, or not a JPEG / PNG / WebP image, e.g. HEIC, GIF or PDF (judged by its bytes, not its name). No credit is taken.

## Fix

Save the slip as an image (a screenshot from the bank app) and send again, or send the QR text instead.
