Are files uploaded for this tool?

This browser tool processes the selected media locally on this device. The file is not uploaded to ArtPlayer servers for this workflow.

Will the export have a watermark?

No. ArtPlayer browser tools do not add watermarks to exported files.

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

Use a compatible image created with this tool and enter the exact bit length recorded during embedding.

No. It can tolerate some compression or damage, but strong resizing, cropping, rotation, filtering, or recompression may prevent reliable extraction.

No. This is an ownership and tracking mark, not encryption or tamper-proof proof.

Three steps to finish the browser workflow.

1
Choose an image
Drop a JPG, PNG, or WebP image here.
2
Choose embed or extract
Embed hidden text in the image, or enter the saved bit length to extract a compatible watermark.
3
Save the result
Download the watermarked PNG after embedding, or copy the recovered text after extraction.

Core details about privacy, browser support, output, and practical limits before you start.

Hide UTF-8 text without placing a visible logo over the image.

Extract compatible text with the saved bit length.

A Web Worker processes the pixels without uploading the image.

Check supported inputs, output formats and usage requirements before you start.

Supported input	JPG, PNG or WebP images.
Output result	A PNG with an embedded mark, or extracted text and bit-length information in extraction mode.
Processing and privacy	Processing runs on this device. Source media is not uploaded for this workflow.
Browser requirements	A modern browser with local file access and support for the selected media format.
Usage limits	Up to 16 million source pixels. Extraction needs the correct bit length; resizing, cropping or recompression may damage the mark.
Will the watermark survive every edit?	No. It can tolerate some compression or damage, but strong resizing, cropping, rotation, filtering, or recompression may prevent reliable extraction.
