Output Formats
Batch Watermark Image can output in four formats. Here’s how to choose.
Same as Input (default)
Keeps each image in its original format. A JPG stays JPG, a PNG stays PNG, a WebP stays WebP.
Use this when: You don’t need to change formats — you just want to apply the watermark and move on. It’s the simplest option and avoids any unnecessary re-encoding.
JPG
JPEG compression — high quality (92%) with a small lossy artifact.
Pros:
- Smallest file sizes
- Universal compatibility — every app, website, and print lab accepts JPG
- Ideal for photographs (continuous-tone images without hard edges or text)
Cons:
- Lossy — each save introduces a small amount of compression artifact
- No transparency support
Use JPG when: You’re sharing photos online, sending to a print lab, or need the smallest files. The 92% quality setting used by Batch Watermark Image is above the threshold where artifacts are visible under normal viewing.
PNG
Lossless compression — no quality loss, larger files.
Pros:
- No compression artifacts — pixel-perfect output
- Supports transparency (alpha channel)
- Ideal for graphics, illustrations, logos, images with text overlays
Cons:
- Larger file sizes than JPG (often 3–5× bigger for photographic content)
Use PNG when: Your images have hard edges, logos, or transparency — or when you want an archival copy with zero quality degradation.
WebP
A modern format from Google — smaller than JPG at equivalent quality.
Pros:
- Excellent compression — smaller than JPG at similar quality
- Supports transparency
- Good for web distribution
Cons:
- Not universally supported — some older software, print labs, and stock platforms don’t accept WebP
- Not the standard format for traditional photo workflows
Use WebP when: You’re preparing watermarked images for web publishing and you know your platform supports it.

A note on TIFF
Batch Watermark Image reads TIFF files as input but does not output TIFF. If your workflow requires TIFF output, export as PNG (lossless, same quality) and convert using a free tool like IrfanView or GIMP.
