A photo collage maker that combines several pictures into a single clean grid image and exports a high-resolution PNG — without uploading anything. It is built for quickly assembling a moodboard, a before-and-after pair, a product sheet, a trip recap or a social post, all from photos that stay on your own device. Pick a layout, drop a picture into each cell, tune the spacing and colours, frame each shot, and download the finished collage in seconds.
How it works
Choose one of eight grid layouts — from a simple side-by-side pair up to a packed 4x4 grid, including asymmetric layouts with one large feature photo. Click a cell to select it, then add a photo; you can also drag several files in from your file manager at once and they will fill the empty cells in order. To rearrange, drag any placed photo onto another cell and the two swap.
Every photo is fitted to its cell using a cover fit, so it always fills the space with no letterboxing. Because that can hide part of a wide or tall image, each cell has its own zoom and pan sliders so you decide exactly which part shows. The style controls let you set the gap between photos, an outer border, the corner radius of each tile and the background colour behind everything — handy when you want a coloured mat or want the tiles to bleed edge to edge.
The whole collage is drawn on an HTML canvas. The preview is a downscaled copy of exactly what gets exported, so what you see is what you get. When you export, the same drawing runs again at full resolution and the result is saved as a PNG. Nothing is sent anywhere — image decoding, layout and export all happen locally, which is why it works offline and keeps private photos private.
Example
Suppose you have four holiday photos and want a square Instagram post. Pick the 2x2 grid, set the aspect to Square 1:1 and the width to 1600px. Drag all four files onto the preview — they drop into the four cells in order. One photo is a wide panorama, so you select that cell and lower its zoom a touch and pan left so the horizon sits where you want it. You set the gap to 16px and the background to white for a clean framed look, give the tiles a 12px corner radius, then download a crisp 1600×1600 PNG ready to post.
For a print-quality moodboard, switch the width to 3000px and the layout to the Feature + 2 option to highlight one hero image alongside two supporting shots. Everything is calculated in your browser — no numbers, and no photos, are ever uploaded.
