How to check PSD files before BMP delivery on Mac

Import PSD files, run Check Batch, and compare the Photoshop composite with its verified BMP before saving any output.

3 stepsUpdated Nov 12, 2026Get PSD to BMP
What you'll achieve
Your workset shows the included PSD files as Ready, and the selected document displays a Fit comparison between the saved composite and the verified 24-bit RGB BMP.
What you need
  • PSD to BMP installed on a Mac.
  • One or more supported PSD documents with saved merged-composite pixels.
PSD to BMP shows three ready Photoshop documents and a side-by-side comparison of a mountain image with its verified BMP.

PSD to BMP can check the BMPs generated from supported Photoshop documents before you save a delivery batch. This walkthrough imports three example PSD files, runs the real Check Batch operation, and shows the saved PSD composite beside its verified BMP. Follow the same process with your own documents.

  1. 1.Open PSD to BMP

    Open PSD to BMP on your Mac. The empty workset displays Add PSD Files in the center, ready for the Photoshop documents you want to convert.

  2. 2.Add the Photoshop documents

    Click Add PSD Files and select the PSD documents to check. The workset lists each admitted file with an included checkbox. The example shows three included PSD files and a reminder that Check Batch is required before the BMP pixels can be compared.

    The workset lists three included PSD documents, each marked Not checked, with a Check Batch required message in the main area.

  3. 3.Check the batch and compare the BMP proof

    Run Check Batch using the checkmark-seal action in the toolbar. Once the operation finishes, confirm the included files show Ready. Select a file in the workset and use Fit to inspect the saved PSD composite beside the verified BMP. Choose Actual Pixels if you need to inspect a 1:1 region before delivery.

    Three PSD files are Ready after Check Batch, and the selected mountain photo's saved composite and verified BMP are compared side by side in Fit view.

After the last step

No files have been delivered yet.

Tips

  • The workset checkboxes choose which PSD files are included in Check Batch; selecting a row chooses which file is shown in the comparison.

  • Use Fit to compare the entire source with its BMP, and Actual Pixels to inspect a bounded 1:1 region.

  • Watch outCheck Batch verifies candidate BMPs but does not save or deliver them. Review the results before opening the delivery workflow.

  • Watch outThe BMP preview uses the saved merged composite of the PSD, not editable Photoshop layers. PSD to BMP does not resize images automatically.
