How your files are processed
Files are uploaded and processed on our servers, then made available for download.
What this tool does
Add watermark composites text or a small logo PNG with adjustable opacity and placement.
Creates review proofs, © lines, or draft stamps before you share pixels outward.
- Raster in, raster out — Add watermark reads common JPEG, PNG, and WebP sources and writes the file type the form advertises—alpha PNG, recompressed JPEG, or plain TXT for OCR.
- Server-side models — Matting, geometry, and OCR use tuned backends instead of single-threaded in-tab scripts on huge files.
- Still too big? — After editing, run the matching compressor profile if email or mobile data still rejects the bytes.
How to use Add watermark?
- Upload — choose the file (or files, if the tool allows multiple) in the supported formats listed on this page.
- Configure — set options such as dimensions, watermark text, or OCR language using the fields above.

Output quality tips for Add watermark
Sharpness depends on source resolution, JPEG quality sliders, and whether the tool re-saves lossy formats.
Keep a PNG or TIFF master before you distribute aggressive JPEG. Compare downloads zoomed to 100% before you replace archive copies.
Add watermark: /utilities vs server image tool
Browser utilities (/utilities)
Color pickers, EXIF viewers, and text helpers run as JavaScript in your tab. Bitmaps you open there never upload to FileConvert.
This image tool (upload)
Add watermark composites semi-transparent text or a second PNG logo layer atop your photo using server-side blending.
Skip Add watermark when you only need hex codes—use /utilities. Use Add watermark when opacity, margins, and placement must survive export.
Troubleshooting
- Upload fails or stalls: refresh the page, try another browser, or pause strict blockers for this site.
- Extension mismatch: compare your filename with the types named on this page above the upload control.
- Unexpected output: verify time ranges, pixel boxes, OCR languages, or watermark opacity, then rerun once.
- Large file limitations: Add watermark jobs can exceed upload or processing limits; try a smaller image first.
- Viewer differences: Safari, Chrome, and design apps tint PNG or WebP differently—open the download in the final app before publishing.
