Signet: Batch Watermark

Signet is a private batch watermark maker for photographers, creators, online sellers, and small businesses. Add text or a transparent logo to multiple photos, review every image, and export dependable new copies without sending your media to a server. BATCH WATERMARK PHOTOS Select a group of photos once and apply one consistent watermark across the batch. Signet keeps relative size and placement coherent across portrait, landscape, square, and cropped images. ADD TEXT OR LOGO WATERMARKS Create multiline text watermarks or import a transparent PNG logo. Adjust text, color, alignment, size, placement, rotation, opacity, and straight or diagonal tiling. ADJUST INDIVIDUAL PHOTOS Review the batch before export. If one photo needs a different position, size, rotation, opacity, or hidden layer, change only that item without changing the rest of the batch. EXPORT NEW JPEG OR PNG COPIES Choose JPEG or PNG output, dimensions, quality, metadata handling, and filename behavior. Signet reports which items completed, which failed, and which failures can be retried. Successful items are not repeated when you retry failed siblings. YOUR ORIGINALS STAY UNCHANGED Signet opens selected source photos as read-only content. Every successful export is a new file. Cancelling a run does not mark partial files as complete, and a failed item does not overwrite its original. PRIVATE, ON-DEVICE PROCESSING Your photos, watermark text, logos, previews, and exports are processed on your Android device. Signet uses Android system pickers so you choose the media it can access. The core workflow works offline and does not require an account. UNLIMITED LAUNCH EDITION The initial Android release has unlimited photo exports within the supported media, storage, memory, and device limits. It has no ads, subscriptions, purchases, credits, or paywall prompts. Signet never adds its own watermark to your output.
