A free bulk watermark tool that never uploads
Drop photos, dial in a text or logo watermark, apply to all, download a ZIP. Nothing leaves your device.
Most online watermark tools batch-limit free users to a handful of images, or watermark the output with their own brand. This one has neither — as many images as your device can handle, no output branding, no signup.
What you can control
Text watermarks — font family, color, size (as % of image width), opacity, rotation. Six curated fonts including mono, sans, serif, elegant serif, script, and Impact.
Logo watermarks — any PNG (transparency preferred), JPG, or WebP. Same opacity, rotation, size controls.
Placement modes — 9-point anchor grid (corners + edges + center), tile (grid pattern), or diagonal (repeating across image at an angle — great for portfolio protection).
Frequently asked
Is this really free?
Yes — no signup, no output watermark, no daily cap, no batch limit.
Are my photos uploaded?
No. Watermarking uses the canvas element in your browser. Nothing is uploaded.
Can I use my own logo?
Yes — drop any PNG (transparency preferred), JPG, or WebP as the watermark. Position, opacity, size are all tunable.
What is tile mode good for?
Anti-theft on portfolio photos. Tiling a diagonal watermark across the entire image makes cropping it out impractical.
Does output preserve source quality?
Output is at the full source resolution. PNG is lossless; JPEG/WebP use the quality slider you set.
Is there a batch limit?
No — as many images as your device memory allows.
Commercial use?
Yes, free for any use, no attribution required.
