A corner credit suits a photo you want people to view clearly. A repeating mark is useful for a review copy because it also covers the middle of the image. Both layouts use the same settings across the selected batch, so check a portrait and a landscape image before exporting.
Before you start
- Keep your original images. The tool exports a new PNG and does not overwrite the source file.
- Use still PNG, JPEG, WebP or BMP images. Convert HEIC photos before selecting them.
- For a logo, prepare a transparent PNG if you want the picture to show around the mark. A JPEG logo retains its rectangular background.
Follow the steps
Select the source images
Choose or drop up to 10 images. Use the preview selector to move between them; selecting a new set replaces the current set.
Choose text or a logo
In Text mode, enter a short credit or review label. A line break creates another text line; line height changes the distance inside that label. In Logo image mode, choose your mark separately.
Choose the placement
Select Tile entire image for repeated marks. Text tiles use a font size in pixels, horizontal gap and row gap. For a single mark, choose one of the five positions, then adjust its width and margin as percentages of the image.
Balance coverage and legibility
Start with 30% opacity and a 30° rotation. Increase opacity if the mark disappears on bright areas, or reduce it if it obscures the subject. For tiled text, increase the gaps when letters overlap.
Inspect the complete batch and download
Switch through every preview. Download PNG exports the selected image; Download all as ZIP applies the same settings to every selected image. Open at least one exported PNG at full size before sharing.
Worked examples
A review copy of a product photo
For a 1600 × 1200 photo, try “REVIEW COPY”, tiled text, 32 px type, 80 px horizontal gap, 70 px row gap, 30% opacity and 30° rotation. These are starting settings, not a required preset.
If the label is too dense, raise the gaps first. Changing line height affects the lines within a multiline label; it does not replace the row-gap control.
Why three files may need individual downloads
Three 4000 × 3000 photos contain 36 million pixels in total. Each is below the 24 MP per-image limit, but their combined ZIP export exceeds the 24 MP batch limit. Download them individually, or resize copies first. File size in MB does not tell you the pixel count.
Text size behaves differently in each layout
A single text watermark uses a percentage width and is fitted inside the image margins after rotation. A tiled text watermark uses a fixed pixel font size, so the same 32 px label looks proportionally smaller on a much larger photo. Mixed image dimensions deserve individual preview checks.
Use the exported image for the final check
The live preview is reduced for display. The PNG export uses the original image dimensions. Inspect text edges, logo backgrounds and coverage on the downloaded image, especially if it will be printed or cropped later. A visible watermark is a label; it cannot prevent copying or removal.
Check the result
- The watermark remains readable on both the lightest and darkest areas.
- Every selected image uses the intended layout and no important subject is covered.
- The downloaded PNG opens correctly and has the expected pixel dimensions.
Limits and boundaries
- Selection: up to 10 images, 15 MB each and 30 MB total. Images must be at most 8192 pixels per side and 24 MP each.
- ZIP export: at most 24 MP across all source images. Use individual downloads for a larger combined batch.
- All exports are PNG. A PNG made from a JPEG can be larger than the original; this tool is not a compression workflow.
- Animated images and HEIC are unsupported. The same watermark settings apply to the entire batch.
