Easy Watermark - Photo & Logo
Batch stamp, original quality
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Build one signature watermark, then put it on everything. Photos or videos, portrait or landscape, it always lands the same way.
ORIGINAL QUALITY
Exports at maximum quality. Run the same photo through five times and the color barely moves. Exif capture data is kept. You can also choose lossless PNG output.
BATCH
Up to 30 files at once, at exactly the position, size and opacity you saw in the preview. If even one file fails, the file name is shown. Nothing disappears quietly.
TILED PATTERN
Diagonal repeated text across the whole frame, with three ready made samples. Good for fan photos and for listing photos.
VIDEO
Length, frame count and audio all stay as they were. The audio is passed through untouched, so nothing plays back slowly and nothing drifts out of sync.
SAME LOOK IN ANY ORIENTATION
Size is measured against the long edge, so a portrait photo and a landscape photo get the same looking mark.
STAYS ON YOUR DEVICE
Photos and videos never leave this iPhone. No account, no sign in, no ads.
HOW IT WORKS
1. Pick a photo or a video
2. Drag to move it, pinch to resize it
3. Save
Your original photo is never rewritten. A new photo is added to your library.
PRICING
You can go all the way through saving a stamped photo without paying (3 files per run, one saved watermark, videos up to 30 seconds).
Pro is a single payment of 1,300 JPY or the local equivalent. There is no monthly charge. Pro lifts the file count and video length limits, lets you keep as many saved watermarks as you like, and unlocks lossless PNG output and all five fonts.
Photos and videos you already saved stay with you even if you stop using Pro.
PLEASE NOTE
A watermark attaches the origin of a picture to the picture itself. It is not a legal protection and we do not promise one.
