Watermarking Images Without Losing Quality: Tiled vs Corner Marks

Once an image leaves your hands, chasing copies is hopeless — marking them before they travel is the pragmatic move. The Image Watermarker stamps text over JPG and PNG files with a live preview, entirely in your browser.

Two layouts, two purposes

Anchored places a single mark in one of nine positions — the classic bottom-right copyright line. Subtle, professional, and the default for finished portfolio work where aesthetics win.

Tiled repeats the text across the whole frame on a lattice, usually rotated −30°. Cropping out a corner mark is trivial; cropping out a diagonal field of marks means destroying the image. That's the layout for client proofs and pre-delivery drafts.

What's actually drawn

The watermark renders on a canvas at the image's original resolution: the text is measured, the anchor or tile lattice computed, then drawn with your opacity, color and rotation. PNG output is lossless; JPG re-encodes at high quality. No re-upload, no watermark service watermarking your watermark.

Tuning that works in practice

• Opacity 25–40% reads clearly without wrecking the composition; above 60% reads as hostile.
• Rotation −20° to −35° follows the eye's diagonal; ±90° looks like a mistake.
• Tile gap controls density — tighter for protection, looser for legibility.

What a watermark is not

A watermark is attribution and deterrence, not DRM. Determined removal is always possible with enough editing; the goal is making casual theft visibly not worth it. For provenance that survives cropping, pair the mark with embedded metadata before publishing — or strip it deliberately with the EXIF & Metadata Stripper when you want zero extras leaving your machine.
