Watermark Tool for Listing Photos, Batch Preview Watermark in Your Browser, 8 Transparent PNG Overlays, Offline HTML App

Preview watermark tool for listing photos by Envelo Watermark.

Show your work beautifully without giving it away. Put a visible watermark on a whole batch of product images right in your web browser and export them in one ZIP. Your images are processed on your device and never uploaded.

WHAT YOU CAN DO
• Add PNG, JPG or WebP images: choose, drop or paste, up to 50 at a time
• Your text and/or logo, opacity, 4 colours and a soft shadow
• A corner, the center or a tiled diagonal pattern with angle and spacing. Size and margin follow each image, so a mixed batch looks the same
• Export one ZIP: JPG with a quality setting or PNG, the same pixel size as the originals, your own file-name ending
• Photo details (EXIF: camera, date, location) are shown on import and removed by default
• Before and after slider, download one image, print a proof sheet
• 8 ready overlays as transparent PNG for any photo or design program: PREVIEW pattern, SAMPLE badge, PROOF stamp, DIGITAL DOWNLOAD band, light and dark

HOW IT WORKS
1. Download the ZIP and START-HERE.pdf from Etsy after checkout.
2. Unzip and open Envelo-Watermark.html in your web browser. No account and no internet needed.
3. Try the example, then add your own images and export.

WHAT YOU RECEIVE
• START-HERE.pdf (0.12 MB)
• Envelo-Watermark-v1.0.zip (3.33 MB)
Inside the ZIP:
• Envelo-Watermark.html: the app, opens in your browser by double click and works offline
• Envelo-Watermark-Planner.xlsx: spreadsheet that plans a batch (text size, margin, position and file name per image size): My Images (blank), Example and How to use
• templates/: 8 ready watermark overlays, transparent PNG: PREVIEW diagonal pattern, SAMPLE corner badge, PROOF stamp and DIGITAL DOWNLOAD band, light and dark
• examples/: the example settings as a backup file (1 file)
• LICENSES.txt and WHAT_YOU_GET.txt

IMPORTANT BEFORE BUYING
• This is a digital download. Nothing is shipped.
• A visible watermark makes copying less attractive and shows where an image came from. No tool can stop someone from copying or editing an image.
• Your images are not saved between sessions: add them again after you close the tab. Your settings stay.
• Very large images (over about 16.7 million pixels) are saved at the largest size the browser can draw.
• Nothing is uploaded. No account, no subscription. English only.
• For use in your own shop or business, on your own images. Please don't resell or share the files or the overlay templates.
• Not made or endorsed by Etsy.
• The app, its logo, the overlays and the texts were made as code with the help of an AI coding assistant. No AI image generators were used.
