Image Resize & Watermark
What it does
Two operations in one local pass: resize a batch of images (by target width, target height, or a percentage — aspect ratio always preserved) and stamp a text watermark with nine placement positions, adjustable opacity and text size. The watermark renders with a soft dark outline so it stays readable on both light and dark photos. Output is WebP at high quality.
Everything runs in your browser; your images never leave the page.
How to use
- Drop one or more images.
- Pick the resize mode and target (or leave Original for watermark-only).
- Type the watermark text and choose position, opacity and size.
- Press Apply and save each result.
Examples
A 4032×3024 photo resized to width 1200 becomes 1200×900 — exactly the aspect-preserving dimension bloggers need.

Good to know
- Resize keeps the aspect ratio: setting width scales height automatically, and vice versa.
- Watermark size is a percentage of the image’s shorter side, so one setting works across a mixed-size batch.
- Output is WebP 92 — convert to PNG with the Image Converter if you need lossless.
