Image Watermarking

Add visible raster watermarks in your browser: text mode (custom string, font size 10–120, white fill with stroke) or image mode (second PNG/JPEG/WebP/GIF scaled to 6–45% of the base width), opacity and placement (top left/right, center, bottom left/right), live preview, then download PNG, JPEG, or WebP with quality for lossy formats. Canvas compositing stays local—no upload. Not invisible EXIF copyright metadata; GIF animation is not preserved on export.

What does Image Watermarking do?

Dynamic Duniya’s Image Watermarking composites a visible layer onto a base JPEG, PNG, WebP, or GIF using the Canvas API. Switch between Text mode—type a label, pick font size, and render semibold system-ui text with a subtle stroke for readability—or Image mode, where you upload a second raster (your logo or badge) and scale it between roughly six and forty-five percent of the base image width. Opacity and placement (top left, top right, center, bottom left, bottom right) apply to either mode; a live preview updates before you download PNG, JPEG, or WebP with an optional quality slider for lossy exports.

Raster overlays vs invisible rights metadata

This tool paints pixels you can see. It does not embed cryptographic signatures, invisible forensic marks, or replace IPTC/EXIF copyright blocks. Treat it as a quick way to produce draft previews, social posts, or internal mock-ups—not a substitute for legal licensing workflows.

Privacy and GEO

Base and watermark files stay in your browser tab; nothing is uploaded to Dynamic Duniya application servers for compositing. Marketing and creative teams in India, the United States, the United Kingdom, the EU, and elsewhere can brand imagery without routing assets through a third-party API, provided local policy allows normal site JavaScript.

Frequently Asked Questions

Is my base image uploaded?

No. Files are decoded with the File API, drawn to a canvas, and exported as a Blob for download entirely in your browser.

Will watermarks stop screenshots or piracy?

Visible overlays appear in screenshots like any on-screen content; they are not DRM and can be cropped or edited by determined users.

Can I use custom fonts for the text watermark?

Text uses the browser’s system UI stack at bold weight for predictable results. For brand-specific typefaces, design in desktop software and use Image mode with a transparent PNG logo instead.

Does GIF animation stay in the export?

The merged canvas is encoded as a static PNG, JPEG, or WebP file; motion from GIF sources is not preserved.

Which export format should I pick?

PNG keeps lossless detail and transparency when the base image had alpha; JPEG and WebP are smaller for photographic bases—tune the quality slider to taste.

Is Image Watermarking free worldwide?

Yes. Usage is free at the point of use; structured data lists a zero-price offer for consistency with other Dynamic Duniya utilities.

Image Compression

New

Compress JPEG, PNG, WebP, or GIF on the server (up to 10 MB per file). Drag-and-drop or browse, set quality 1–100 and optional max width in pixels (scales down only; default 1920). See before/after byte sizes when meta is returned, then download the compressed image.

Image Resize

New

Resize or reframe JPEG, PNG, WebP, or GIF entirely in your browser: set target width and height, optionally lock aspect ratio, then choose how pixels map—Fit (letterbox on white), Cover (center crop to fill), or Stretch. Export as JPEG, PNG, or WebP with a quality slider for lossy formats. Decoding and canvas work stay on your device (no upload). Animated GIFs flatten when exporting to static formats.

Image Format Converter (JPG / PNG / WebP)

New

Convert JPEG, PNG, WebP, or GIF sources to JPEG, PNG, or WebP in your browser: live preview updates as you switch format, quality slider for lossy JPEG and WebP, lossless PNG (no quality control). Decoding and encoding stay on your device—no upload. GIF sources decode to a static frame; animation is not preserved in the output file.

Rotate & Flip Image

New

Rotate JPEG, PNG, WebP, or GIF photos in 90° steps (90°, 180°, −90°), flip horizontally or vertically, combine transforms, reset to original, and preview on canvas—all in your browser. Download keeps PNG/WebP as those types and uses JPEG for other extensions (including GIF sources). Live PNG preview; no upload. GIF animation is not preserved on export.

Add Text to Image

New

Overlay a single line of text on JPEG, PNG, WebP, or GIF photos entirely in your browser: edit the caption, font size (8–200px), fill color, horizontal and vertical position (0–100%), and optional dark stroke for contrast. Live preview; download as PNG, JPEG, or WebP with a quality slider for lossy formats. Canvas rendering stays local—no upload. GIF animation is not preserved when exporting.

Image Background Remover

New

Cut out subjects in your browser with the IMG.LY ONNX + WASM segmentation model (ISNet quantized): first visit downloads WASM and model weights from their CDN (~tens of MB, then cached). Long edges above 2048px are scaled down before inference; max file size 8MB for stability. Export transparent PNG with checkerboard preview. Your pixels are not uploaded to Dynamic Duniya—only model assets load from the vendor CDN.
