Add photos to see your watermark preview.

Photos and logos stay on your device. Original files are unchanged. Exported photos keep their dimensions and format, but camera metadata is removed.

Watermark a batch while keeping images usable

Apply the same text or logo to several JPG, PNG or WebP images. Preview both light and dark photos before exporting. A visible watermark can identify your work, but cannot prevent copying or removal.

Step by step

  1. Add the photos and choose text or a logo. For a logo with transparent edges, use a transparent PNG.
  2. Set size, opacity, placement and color. Move through the previews to check that the mark does not cover important content.
  3. Apply the watermark, review successful and failed files, then download the selected result or a ZIP of successful results.

Settings and limits

Relative size
Size follows image width. Long text is reduced to fit; logo proportions are preserved, so wide and tall marks differ.
Opacity and placement
Choose enough contrast to read the mark without hiding the subject. Corner placement leaves more of the center visible.
Output quality and format
The output keeps the input format and pixel dimensions. Quality affects JPG and WebP compression; PNG is lossless.

Worked example

Open sample.png and enter SAMPLE. Use size 7%, opacity 75%, white text and the bottom-right position.

Example input

SAMPLE · 7% · 75% · #ffffff

Expected result

1200 × 800 px · PNG

The exported sample stays 1200 × 800 pixels. Compare sample-watermarked.png with the original before applying these settings to other photos.

Questions and troubleshooting

Why is one watermark smaller than expected?

Text shrinks when it would exceed the available width. A tall logo can also reach the height limit first.

Why are some files missing from the ZIP?

The ZIP includes successful results only. Check the failed count and retry those images separately with smaller inputs.

Can I undo the watermark after downloading?

The mark is merged into the exported pixels. Keep the original image; it cannot be removed as a separate editable layer.
