## What is ImageSeal?

ImageSeal is a photo watermarking tool for creators, photographers, designers, and online sellers. Embed a nearly invisible source mark, add visible text or a brand logo, and verify an ImageSeal mark by importing an image from Photos or Files.

INVISIBLE WATERMARKS  
Embed source information while keeping the image looking natural. Use it to mark portfolio work, product photos, design drafts, and client previews.

BUILT-IN VERIFICATION  
Import an image from Photos or Files and verification starts automatically. If the quick scan does not find a mark, you can run a more thorough deep verification and inspect the recovered source record and technical details.

TEXT AND LOGO WATERMARKS  
Add custom text, an image, or a logo. Adjust placement, scale, opacity, tone, and layout. Use a visible watermark on its own or combine it with an invisible mark.

BATCH PROCESSING  
Select multiple images, apply a consistent watermark, and save the completed batch. Spend less time repeating edits and keep branding consistent.

PREVIEW AND EXPORT  
Compare the original and sealed result before exporting. Save finished images to Photos or send them to other apps with the system share sheet.

PRIVATE BY DESIGN  
Watermark creation and verification happen on your device. No account is required, and your images are not uploaded to a server for watermark processing.

The free plan includes 10 saves or shares each month, along with core creation and verification features. A one-time ImageSeal Pro purchase permanently unlocks unlimited saves and shares, batch processing, and image/logo watermarks. Purchases are handled securely by Apple.

IDEAL FOR

- Photographer portfolios and client previews;
- Product photos and e-commerce branding;
- Artwork, design drafts, and social content;
- Internal source marking for shared images;
- Quick verification of ImageSeal invisible watermarks.

Watermark recovery can vary after cropping, compression, resizing, screenshots, or other edits. ImageSeal assists with content marking and source verification; it is not copyright registration, legal proof, or a guarantee against unauthorized use.
