How to Add a Logo to Your Photos

Adding a logo to a photo is easy to get wrong: the logo shows up inside an ugly white rectangle, or it's a different size on every shot. The fix is mostly about the logo file itself and placing it once for reuse. Here's how.

Start with the right logo file

The white box behind a logo almost always comes from the file format, not the app. A JPG logo has no transparency, so its background — usually white — gets pasted onto your photo. A PNG with a transparent background carries an alpha channel, so only the logo's shapes land.

Which logo file to use

JPG / JPEGNoWhite (or colored) box around the logo
PNG with transparencyYesClean edges, only the logo shows
SVG (vector)Yes, but convert firstExport to transparent PNG for photo apps

Not sure if your PNG is transparent? Open it on a dark background. If you see a white square, it isn't — re-export it with a transparent background before adding it to photos.

Place it once, reuse it forever

Add your logo to a photo (or batch)

  1. Pick the photo or batch you want branded.
  2. Add your transparent PNG logo and drag it to a corner; grid snapping keeps it aligned. A good starting size is around 20–25% of the photo width.
  3. Set opacity — roughly 60–75% reads as a watermark without hiding the image.
  4. Save it as a template so the next batch takes one tap, then export at full resolution.

How do I add a logo to a photo without a white background?

Use a PNG logo that has a transparent background. Its alpha channel means only the logo's shapes composite onto the photo — no white box. A JPG logo can't do this because it has no transparency.

How big should a logo be on a photo?

As a starting point, about 20–25% of the photo's width at 60–75% opacity — visible as branding without covering the subject. Adjust to taste; the mark stays editable.

Can I put my logo on many photos at once?

Yes. Set the logo once and apply it to the whole batch in a single export, with each photo placed for its own dimensions.
