Marklab: Batch Watermark

Marklab puts your mark on your work and keeps your private data out of it.

Add a text or logo watermark to photos, PDFs and videos, stamp a whole set of photos in one pass, and strip the hidden location and device data your camera leaves inside every shot.

Everything happens on your iPhone. Nothing is uploaded, no account is needed, and the app works in airplane mode.

BATCH WATERMARKING
Select a whole shoot, set the watermark once, and let Marklab stamp every photo. Progress is shown as it goes and you can stop at any point. Share the finished set in one step.

WATERMARK ANYTHING
• Photos - JPG, PNG and HEIC
• PDFs - every page, or only the pages you choose
• Videos - MP4 and MOV, with the mark burned into the clip

FULL CONTROL
Text or your own logo. Adjust opacity, size, rotation and spacing. Choose one of nine positions or tile the mark across the whole frame. A live preview shows exactly what you will get, because the preview and the export use the same renderer.

SAVED PRESETS
Keep the settings you use often and apply them again with a single tap. No more rebuilding the same watermark for every job.

HIDDEN DATA
Photos carry more than they show. Most of them store the exact spot where they were taken, the time, and the phone that took them. Marklab lists what a photo is carrying and removes it, leaving the picture itself untouched.

BUILT FOR PRIVACY
No servers, no accounts, no tracking, no ads. Your files never leave the device, which is also why the app keeps working with no connection.
