Remove a photo background for a presentation

Choose a subject that stands out

Use a photo with the whole subject visible and clearly separated from the background. Hair, glass, cables and blurred areas need a closer check: an automatic mask can remove too much or retain part of the background.

Think about the slide’s background before preparing the copy. An edge that looks clean on white may show a fringe over a dark colour. You do not need to remove the background from every photo in the presentation.

Prepare the transparent PNG

PNG preserves transparency. A JPEG has an opaque background and cannot freely reveal the slide’s colour behind the subject.

1. Add the photo and choose Remove background.
2. Select transparent PNG output.
3. Run preparation and inspect the edges in the preview.
4. Compare with the original to check that useful parts of the subject were kept.
5. Save the PNG copy and insert that file into your presentation.

Check it against the slide background

Place the PNG over the colour or image you will actually use. Zoom in to inspect fine details, then view the whole slide at its normal display size.

If the result does not work, try a better photograph or keep the original background. PhotoWisp does not provide a manual brush for rebuilding missing edges.

Manage file size while keeping transparency

A cutout PNG can be larger than the source photo. Check the output file and limit its dimensions if the presentation does not need a very large image.

Converting to JPEG would remove transparency. Keep the PNG for the slide and retain the original separately for other versions later.
