Use a decoded 1600×1200 ordinary photo and enter © River Studio. Choose bottom-right, size 48 px, opacity 60%, rotation 0°, margin 24 px and white. The text anchor is x=1576 and y=1176, aligned to its right and bottom edges.
Verify the complete frame
Export dimensions remain 1600×1200 because watermarking adds a layer without cropping or resizing. Check that the final letters stay inside the lower-right edge and remain readable over the local photo content.
Choose encoding separately
PNG preserves Canvas transparency; JPEG uses the selected matte for any transparent source pixels; WebP uses the browser encoder. The anchor and text settings stay the same, while exact bytes can differ substantially.
Keep a visible watermark in its proper scope
WatermarkLocal creates a newly encoded Canvas image. A visible text mark can be cropped, covered, edited or removed and does not prove copyright, ownership, consent, authenticity or tamper resistance. Use it for ordinary digital publishing only. Do not prepare identity, medical, legal, evidentiary, inspection, emergency, navigation or other safety-critical imagery, and independently verify every important result.
