Whether you’re protecting your photography, branding social posts, or marking proofs before a client pays, a watermark does the job. The trick is making it visible enough to matter without wrecking the image — and applying it to a whole batch without doing each one by hand. This guide covers both.

TL;DR — Use the bulk watermark tool to stamp text or a logo onto every image at once. Set position, size and opacity once; apply to all. Nothing is uploaded.

  • Text watermark — your name, handle or website. Fast, no asset needed, easy to read. Best for attribution.
  • Logo watermark — your brand mark, usually a transparent PNG. Best for a polished, branded look.

You can use either — and a transparent logo sits far more cleanly on a photo than one with a white box around it.

Placement, size and opacity

This is what separates a professional watermark from an amateur one:

SettingRecommendation
Opacity30–60% — present but not overpowering
Position (branding)A bottom corner — subtle, out of the way
Position (protection)Centre, or tiled across the image — hard to crop out
SizeSmall enough to ignore, large enough to read

Tip: If the goal is genuinely to stop reuse, a single corner watermark is easy to crop off. Use a centred or tiled, repeating watermark instead — it can’t be removed without destroying the image.

Step by step: watermark your images

  1. Open the bulk watermark tool and drop in all the photos you want to mark.
  2. Add your watermark — type text and pick a font, or upload a logo.
  3. Set position, size and opacity and preview it live.
  4. Apply to the whole batch — the same watermark goes onto every image.
  5. Download one image or the entire batch as a zip.

Your originals and your logo never leave your device.

Branding vs protecting

Be clear about which you’re doing — they call for different choices:

  • Branding (social, marketing): subtle corner mark, low opacity, your logo or handle.
  • Protecting (proofs, paid work, anti-theft): centred or tiled, higher opacity, harder to remove.

Frequently asked questions

How do I add a watermark to a photo?
Open the photo in a watermark tool, type your text or upload a logo, set its position, size and opacity, and apply. A bulk tool stamps the same watermark onto every image in your batch at once.
What opacity should a watermark be?
Around 30–60%. Visible enough to deter copying, faint enough not to ruin the image. A semi-transparent watermark looks far more professional than a solid one.
Where should I place a watermark?
A corner is subtle and easily cropped out; the centre (or a tiled, repeating watermark) is hardest to remove. Choose based on whether you're branding or actively protecting the image.
Are my images uploaded to watermark them?
No. Everything — your photos and your logo — is processed on your own device. Nothing is uploaded, so your unwatermarked originals stay private.
