Supports JPG, PNG, WEBP, BMP (Pro: Unlimited | Free: 5 Images)Because we use native HTML5 Canvas APIs, your images are compressed using your own device's hardware. You don't have to wait to upload massive folders to a remote server.
Your unreleased product photography never leaves your computer. We have no servers, no databases, and no access to your proprietary files. Complete offline privacy.
Cloud-based image APIs charge monthly recurring fees to optimize your store. We charge a flat $14.99 once. Use it forever across unlimited stores and client projects.
Most image compressors charge recurring fees because they have to pay massive server hosting costs to process your photos remotely. We wrote a custom mathematical engine that forces your own browser to do the heavy lifting locally. Because we have $0 in server processing costs, we pass the savings directly to you via a single lifetime unlock.
If you clear your browser cookies, factory reset your device, or want to use the tool on a different computer, simply scroll to the footer of this page and click the "Restore Purchase" link. Enter the License Key that was included in your original Lemon Squeezy email receipt, and the tool will instantly unlock.
Uploading raw 4000px camera images kills website load speeds, even in WebP format. When enabled, our tool automatically detects oversized images and proportionally scales them down to your defined maximum width (e.g., 1500px) before compression. This guarantees massive byte savings without stretching or losing aspect ratios.
The free test acts as your live preview. You can drag in any folder, and we will process the first 5 images for free. You have full access to test the Watermark Studio on these 5 images to confirm the visual output and mathematical bandwidth savings before deciding to upgrade to the Pro tier for bulk capability.
You can type your brand name into the tool, adjust the opacity and placement, and our engine will mathematically burn the text directly into every photo in your batch simultaneously, protecting your catalog from automated scrapers.
