    Image Overlay — FAQs

    How do I overlay one image on another?▾

    Upload your base photo, then add the image you want to layer on top. UnderlayX AI lets you position, resize, and blend the overlay so it sits naturally on the base image — no design software required, all in your browser.

    Is this image overlay tool free?▾

    Yes. Your first image overlay is free with no watermark. After that, upgrade to the Creator plan ($9/mo) for unlimited access to all features.

    Can I blend images together, not just stack them?▾

    Yes. Beyond simple stacking, you can adjust opacity, position, and layering order to genuinely blend two images together — great for double-exposure looks, watermarks, logos, or creative composites.

    What's the difference between photo overlay and text behind image?▾

    Photo overlay layers one image on top of (or behind) another. If you want to place typography behind a person or object in a single photo instead, try our dedicated text behind image tool.

    Do I need design experience to overlay photos?▾

    No. The editor is built for anyone — drag your images in, adjust position and size with simple controls, and download. No prior editing or design skills needed.

    What image formats and quality can I export?▾

    You can upload JPG, PNG, WebP, and HEIC images and download a high-resolution overlay result, ready for social media, print, or web use.
