Image Watermark

Watermarks as many as 20 images at once with text, a logo or both, using nine anchored positions or a bounded staggered tile, while preserving each image's full pixel dimensions for local JPG, PNG or WebP export.

How to use it

1. 1Add up to 20 JPG, PNG, WebP or GIF files, then enter watermark text, add a logo, or use both; remove any source you do not want in the batch.
2. 2Choose a single anchor or tiled mode, then adjust typeface, size, outline, logo scale, opacity, rotation, padding, offsets and tile gap against the selected-image preview.
3. 3Choose Same as source, PNG, JPG or WebP and the JPG/WebP quality, then process the batch; changed settings are flagged until you process again.
4. 4Download each named result or trigger the separate downloads for the whole processed batch.

Example

Input

photo.jpg at 1600 × 900 with the defaults: white © My Watermark text, contrasting outline, bottom-right, 4% size, 45% opacity and 3% padding

Output

photo-watermarked.jpg at 1600 × 900, with 64 px base text and a 27 px edge inset, encoded at the default 90% JPG quality

The text size is 4% of the 1600 px width and the inset is 3% of the shorter 900 px side. The preview is downscaled for responsiveness, but export redraws at the source dimensions. Same as source preserves the dimensions and file family, not the original compressed bytes.

What happens to your data

Sources, logo, preview and exports stay in this browser tab; there is no upload. Limits are 30 MB and 16 megapixels per image, 24 megapixels across a batch, 16,384 px on either side, and 10 MB/12 megapixels/8,192 px per side/20:1 aspect for the logo. Tiled export caps draw work by widening spacing only on pathological aspect ratios. Canvas export re-encodes pixels, so metadata, layers, animation and original colour profiles are not retained; an animated GIF becomes a browser-decoded still-frame PNG when its source format cannot be written back.
