Overlay Studio is a browser-based editor for adding layers, overlays and watermarks to images, then exporting the results. You can adjust each layer’s position, size, rotation, blend mode and opacity, or repeat a watermark across an image with configurable spacing and opacity. For batch work, it applies a watermark to multiple images at the same relative size and position and downloads them together as a ZIP; the free batch limit is 25 images at once. Exports include PNG, JPG and WEBP at full source resolution, with crop, resize and quality controls. Editing and export happen locally in the browser, and the site says images are not uploaded to its servers. The editor can also work offline after it loads. Optional background removal downloads a model and code from public package CDNs; the site says the image remains on the device. Overlay Studio is free, with no export paywall or forced watermark, and is available in browsers, Android and iOS.
Who it is for
It suits small businesses, creators, sellers and developers who need to brand or protect images without desktop software. Its browser-based workflow also fits users who want to process images locally or in batches.
