PlainMark is a watermark maker that puts your name, logo or website on your photos and videos, then saves them at full size. Every feature is free: no subscription, no credits, no trial, no ads and no account. It works offline and your photos never leave your phone.
WHAT YOU CAN DO
• Text watermarks: 10 fonts (from clean sans to handwritten signature), any colour, size, opacity and rotation
• Shadow, outline or a background box so your mark stays readable on any photo
• Logo watermarks: import any PNG or picture. A plain background (for example white) can be removed in one tap
• Drag to move, pinch or use the corner handle to resize and rotate, or snap to a corner
• Repeat the mark across the whole photo as a diagonal pattern that is hard to crop out
• Batch: watermark many photos at once. The watermark keeps the same margin from the corner on every photo, whatever its size or shape
• Videos: burn the watermark into your videos at their original resolution, sound included
• Save your watermarks and reuse them with one tap. Your last watermark is always remembered
• Undo and redo
• Quick inserts for ©, ®, ™, the year, today's date and your own details (name, website, handle, email, phone)
• Light and dark mode
YOUR PHOTOS, YOUR WAY
• Saves at the original size and shape. No forced crop, no lower resolution
• Keep JPEG/PNG, or choose JPEG or PNG; pick the JPEG quality
• Optional smaller sizes (2048 or 1080 px) for social media
• Removes the location from saved copies by default; date and camera details stay
• Your originals are never changed. Watermarked copies go to Pictures/PlainMark and Movies/PlainMark
PRIVATE BY DESIGN
PlainMark has no internet permission and asks for no storage permission: you choose photos in Android's own picker. No ads, no analytics, no tracking, no sign-up.
Use it to add a watermark to photos, put a logo on a photo, add text to photos, batch watermark a whole shoot or watermark a video. Share photos from your gallery straight to PlainMark to watermark them.
