How to watermark multiple photos on Mac
Apply a single copyright text watermark to a batch of photos, prepare the marked versions, and review all four results before exporting.
- What you'll achieve
- Four photos display the same white copyright-year watermark in the bottom-right corner, and all four prepared candidates have been marked as reviewed.
- What you need
- Watermark: Sign Every Photo installed on macOS 14 or newer.
- Four photos to watermark; this example uses four demonstration images.
- A destination for export if you choose to save copies after reviewing.

Watermark: Sign Every Photo lets you configure one text watermark and reuse it across a batch of images. This walkthrough reproduces the four-photo review board from the macOS 2.1 App Store screenshot, including the automatically updated copyright year, consistent corner placement, and individual review.
1.Import the first photo
Open Watermark: Sign Every Photo and use Import images to add your first photo. It appears in the review board, with the photo shown in the main preview.

Choose text in Watermark type, then use Quick insert year in the text controls. The Watermark Text field uses a © year token, so the preview can display the current year.

Set Text size to relative, adjust Size (%) until the mark is readable, and raise Opacity if needed. Select Position: Bottom Right to place the text consistently in the photo's lower-right corner.

Use Import images to add three more photos to the same batch. The left review board shows all four sources while the single watermark configuration stays active.

Click Prepare to generate a marked preview for each photo. Check that four candidates appear in the review board before reviewing them.

Use Move to unchecked to select a candidate that has not been reviewed. Inspect its watermark in the large preview, then activate Candidate reviewed for that photo.

Continue with Move to unchecked and Candidate reviewed until all four candidates have been checked. Use Review filter set to all to see the complete batch; every photo should show the shared copyright mark.

The originals remain untouched; exporting the reviewed copies is a separate action.
Tips
Use Text size set to relative and adjust Size (%) so the watermark stays proportional on photos with different dimensions.
Check the mark against both light and dark photo areas. Adjust Opacity if the white mark becomes difficult to read.
Use Review filter to show all candidates when you want to confirm that each image has been checked.
Watch outPrepare generates candidates for review; this walkthrough does not perform the final export. Export separately to save copies.
Watch outThe year token inserted by Quick insert year follows the active year when the watermark is rendered; use a fixed year only if your licensing policy requires it.
Watch outAdding an ownership watermark is not the same as a legal signature or document signing.
