What this inspection checks

Read the encoded bit depth reported by supported raster image structures.

Depending on the format, the report shows JPEG sample precision, PNG bit depth and color type, TIFF depth, BMP bits per pixel, GIF color resolution, or available AVIF and HEIC depth information.

How to inspect the image

  1. 1

    Choose an image

    Select one or several supported image files from your device.

  2. 2

    Review the detected fields

    Open the format details and integrity tabs to review the values found in the file structure.

  3. 3

    Keep the result

    Copy the report or download it as JSON. The original image is not changed.

Frequently asked questions

What does this checker report?

Depending on the format, the report shows JPEG sample precision, PNG bit depth and color type, TIFF depth, BMP bits per pixel, GIF color resolution, or available AVIF and HEIC depth information.

Is my image uploaded?

No. This inspection runs in your browser and does not upload the original image.

Does the checker modify the image?

No. It reads technical fields and produces a report; it does not convert, repair, or rewrite the file.

Is the result a complete file validation?

Bit depth describes file encoding, not the number of colors visible on a particular monitor. Some camera RAW and complex containers may return an unknown or typical value instead of a verified depth.
