About this tool
About Watermark Image
Place a configurable text watermark on JPG, PNG, or WEBP images and export a new copy. The selected image is processed locally in this browser without being sent to a backend conversion server. A visible watermark can still be cropped or edited and is not proof of copyright ownership.
Use Watermark Image when you need to add a visible text watermark to an image. Common uses include mark preview photos, add a draft label, place a simple attribution on shared images.
How to use Watermark Image
- Choose an image.
- Enter the watermark text.
- Adjust position, size, color, and opacity controls.
- Apply and download the watermarked image.
What Watermark Image changes
- Draws the watermark text into the exported image pixels.
- Does not add cryptographic ownership or modify the source file.
Browser-only privacy
The selected image is processed by JavaScript running in this browser for Watermark Image. NoLogPDF does not send the file to a backend conversion API, and file names, contents, form values, passwords, and output data are excluded from site analytics.
Limits to know before using Watermark Image
- A visible watermark can still be cropped or edited and is not proof of copyright ownership.
- Low opacity or poor contrast can make the mark difficult to see.

A visible watermark can still be cropped or edited and is not proof of copyright ownership. Low opacity or poor contrast can make the mark difficult to see.

Why NoLogPDF
Built for sensitive files that should stay on your device
NoLogPDF is designed around browser-only processing. The tools load in your browser, run on your computer, and give you honest limits when a format needs server-grade conversion.
Local-first privacy
Your data never leaves your device
NoLogPDF is built around privacy principles used by serious teams: minimize data movement, avoid unnecessary collection, and make processing limits visible.
Privacy by design
Files are processed locally, so personal documents are not sent to our servers for conversion.
No file profiling
NoLogPDF does not need account profiles, uploaded files, or file-processing histories to run tools.
Sensitive-file aware
Useful for private workflows, but not a substitute for your organization's legal compliance process.
Example use cases
Practical browser-only workflows
Merge contracts and create smaller client-report copies without sending the documents to a conversion service.
Organize assignment pages and use the visible browser-only limits to choose an appropriate conversion workflow.
Delete pages, reorder a packet, add a visual signature or watermark, and review common document metadata.
Work with sensitive local files without an account, file-upload queue, or backend conversion server.
Convert image formats, adjust dimensions, and create PDFs from images in the same local workspace.
Review clear limits when Office conversion, OCR, aggressive compression, or page rendering cannot be exact.
Docs
How NoLogPDF works

The result is generated in-browser and downloaded directly. No backend upload is required.
Quick answers
Frequently Asked Questions
Is NoLogPDF really free?
Yes. The tools run in your browser and do not require an account or payment gate.
Are my files uploaded?
No. The tools run inside the browser with local JavaScript libraries. There is no conversion API behind the page.
Why are some tools marked Beta?
Some PDF jobs need browser rendering or experimental file parsing. Those tools still work locally, but exact layout can vary.
Can NoLogPDF replace every server PDF converter?
Not for perfect Word/PPT reconstruction or heavy compression. The site favors privacy and transparency over fake perfect results.
Do you use cookies or analytics to track me?
Google Analytics collects basic page-view and site-usage information. NoLogPDF never sends file names, file contents, form inputs, passwords, signatures, or conversion data to Analytics. Your theme preference is saved locally in your browser.
How does the helper answer questions?
The helper answers common questions locally. For a genuinely unmatched question, it can send only the text you typed to protected online support. Files, filenames, document contents, passwords, and conversion results are never included.
