Image Watermark
Watermark photos in batch — without a desktop editor

Free, no credit card · Processing runs in your browser — photos stay local until you download

Why Image Watermark on AZTools
Brand a folder of product shots or portfolio images the same way — next to your other tools, not a separate watermark app per batch.
Logo and text together
Upload a PNG logo, add copyright text — or use either one alone.
Nine placement spots
Pin logo and text independently to corners, edges or center.
See before you export
Canvas preview updates as you tweak size, opacity and margin.
Batch download
Watermark all queued images and grab one ZIP file.
Many photos, one watermark setup
Drop or pick multiple images into a queue. Select any thumbnail to preview how your current logo and text settings look on that photo before applying to the whole batch.
- Multi-select upload for JPG, PNG and WebP
- Queue with per-image done or error status
- Switch active image to check placement on different aspect ratios

Your logo, sized and placed
Upload a logo image, toggle it on and adjust scale and opacity relative to the photo. Pick placement on a 3×3 grid — top-left, bottom-center, center and the rest.
- Upload, change or remove logo anytime
- Scale and opacity sliders with live preview
- Independent position from text watermark

Text overlay with full control
Enable a text watermark with custom content — copyright, URL or label. Set size, opacity and color, then place it on its own nine-point grid separate from the logo.
- Any text string as watermark content
- Color picker and relative text size
- Works alongside logo or on its own

Live canvas preview
The selected image renders on a canvas with your logo and text applied in real time as you move sliders or change placement — no guesswork before batch export.
- Debounced preview while you adjust settings
- Margin control keeps watermarks off the edge
- Same layout applied when you watermark all

Apply, review and download
Watermark every queued image with one action using the same settings. Choose JPEG, PNG or WebP output with quality control, then download files individually or as a ZIP.
- Watermark all with shared logo and text setup
- JPEG / PNG / WebP export formats
- Browser-side canvas — no server upload to process

REST API for defaults
Read and update saved watermark preferences programmatically — logo and text toggles, content, positions, opacity, margin and export format — for workflows that open the tool pre-configured.
- getAppState and savePreferences endpoints
- Persist text, placement and export defaults
- Logo file stays in the session; rendering is client-side
