Frequently Asked Questions

Does grayscale change image dimensions?

No. Grayscale conversion keeps width and height unchanged and only transforms pixel values.

Is this conversion done in my browser?

Yes, the entire conversion runs in your browser. No file is sent to any server.

Should I compress after grayscale conversion?

Often yes. After grayscale conversion, applying compression can further reduce output file size.

Is Grayscale Image free to use?

Yes, Grayscale Image on Pixlane is completely free. No account, no signup, and no watermark on downloaded files.

Can I undo the grayscale conversion?

Grayscale conversion removes color data permanently. Always keep your original file as a backup.

Is the output file smaller than the original?

Often yes. Grayscale images have one channel instead of three, which can reduce file size especially for PNG.
