Overlay Images Online — Put Logos, Stickers, and Frames on Photos

Image overlay means placing one or more images on top of a background photo to create a single composite. Common uses include adding a logo watermark to product photos, placing decorative frames on portraits, or combining stickers and icons for social media graphics. Upload a background, add overlays, drag them into position, adjust size and opacity, then export as PNG, JPG, or WebP. Multiple layers are supported — add as many overlays as you need, each independently controlled. All processing happens locally in your browser with zero upload.

Merge Images Online — Free Alternative to PineTools

PineTools is the most searched image merger, but it uploads your files to a server and shows ads. Our free image merger combines photos side-by-side, vertically, or in custom grid layouts with no file upload, no watermark, and no ads. Supports JPG, PNG, and WebP in any combination. Control spacing, alignment, and background color between images. Batch merging lets you process hundreds of image pairs at once — ideal for before/after comparisons, product variant sheets, and e-commerce listings that require consistent paired presentation.

Split Images into Grid Tiles — Instagram Carousels, Puzzles, and Print Mosaics

The image splitter divides any photo into a uniform grid of equal tiles. Specify rows and columns and the tool automatically calculates equal dimensions with no manual cropping. Common uses: Instagram carousel posts (split one wide image into 3 or 9 square tiles to post in sequence), puzzle creation (split into 4×4 or 6×6 grids), large-format print tiling (split a poster into A4 pages for printing and assembling), and app UI asset slicing. Output files are numbered in reading order for easy reassembly.

Add Rounded Corners to Images in Bulk

Modern UI design, social media profile pictures, and app icons all use rounded corners. Our tool applies uniform or custom corner radii to hundreds of images in a single pass — set any radius from 0 to 50% of the shortest edge, or apply different values to individual corners for asymmetric effects. PNG output preserves transparency so rounded edges blend naturally into any background or design layout. No image editing software needed.

Blur and Pixelate Faces Before Sharing Photos Online

Before posting photos to social media, cloud storage, or workplace systems, blurring or pixelating faces is a basic privacy measure for people who didn't consent to being photographed. Our face blur tool automatically detects faces and applies Gaussian blur or pixel mosaic in one click. The pixelate image tool lets you manually draw a box over any region — useful for obscuring license plates, addresses, ID numbers, or any sensitive content. Both tools support batch processing across entire folders.
