Is adding watermarks really free?
Yes, completely free with no limits. Watermark unlimited images of any size, as many times as you want. No app watermark of our own, no signup, no credit card required.
Do my images get uploaded to a server?
Never. All watermarking happens locally on your computer. Your images never leave your device - good for client work and unreleased photos.
Can I use a logo image as the watermark?
Yes. Use a text watermark or load your own logo (a transparent PNG works best), then position and scale it however you like.
Can I control opacity and position?
Yes. Set the opacity for a subtle or bold mark, choose where it sits (corner, center, tiled), and adjust size and rotation.
Can I watermark many photos at once?
Yes. Add a whole folder and FileHop applies the same watermark settings to every image in a single batch.
Will my original images be changed?
No. FileHop writes watermarked copies and leaves your originals untouched, unless you choose to overwrite them.
Does it work offline?
Yes, FileHop works 100% offline after installation. No internet connection is required to watermark images.
What platforms are supported?
Mac (Apple Silicon and Intel), Windows (10, 11). Download the version for your operating system.
