Logomint: Watermark Photos

Logomint puts your logo on photos and videos — many at once. Pick the files, choose a PNG logo with a transparent background, set the position, size and transparency once — and Logomint applies it to every selected photo and video. Edited copies are saved to your library as new items; your originals are never changed. • Batch processing of photos and videos • 9 preset positions with an edge margin, or drag the logo anywhere on the preview • Size scales with each frame, so the logo looks the same on portrait and landscape shots • Adjustable transparency • Keeps photo format (HEIC, JPEG, PNG), location and capture date • Videos keep their sound; output in high-quality HEVC • Optional: keep the original date so copies appear right next to the originals • Works fully offline — no accounts, no ads, no tracking Perfect for brands, shops, photographers, bloggers and anyone who wants to sign their content.
