Sizes matched for you
The fiddly part of merging photos is never the merging — it is that no two photos are the same size. This tool
handles it the way a layout artist would: side-by-side images are scaled to a common height, stacked images to a
common width, and grid cells are equal squares with each photo centre-cropped into its cell. Nothing gets
stretched, and a before/after pair lines up perfectly on the first try.
Everything renders on a canvas in your browser — the live preview is the output, and the download is
re-rendered at the images' full resolution. Going the other direction, the
Image Splitter cuts one image into grid tiles.
Frequently asked questions
My photos are different sizes — do I need to resize first?
No. Side-by-side matches every image to a common height, stacking matches a common width, and the grid centre-crops each image into equal square cells — the collage look, with nothing stretched.
Can I make a before/after image?
That is the classic use: drop the two photos, keep “Side by side”, add a small gap so the boundary reads clearly, and download. The arrows under the preview swap the order.
Are my photos uploaded?
No — the images are drawn onto a canvas in your browser and the combined file is encoded on your device. Nothing leaves it.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
