Combine images into one file — two photos side by side for a before and after, a strip of screenshots, a sheet of four pictures. PIXLFLW does it in your browser: the files are read locally and none of them is uploaded.
What you can do
- Side by side or stacked — a row for wide comparisons, a column when the pictures are wide themselves.
- A grid — 2 × 2, 3 × 3, or as many columns as you type. Photo grid opens on that arrangement.
- Matched sizes — photos from different cameras line up: heights are matched to the smallest one, so nothing is enlarged into blur.
- A gap and a background — up to 500 px between frames, any colour behind them, or none at all if you export PNG.
- Up to 13 pictures — the one you opened with, plus twelve more.
How to merge two images side by side
- Drop both files into the upload area at once (formats: GIF, JPG, BMP, PNG, WEBP, HEIC, TIFF).
- The first becomes the sheet and the rest sit next to it. Reorder them if they came out wrong.
- Set the gap, pick a background colour, and download.
Photos of different sizes
Two pictures rarely measure the same. In a row, "Match to the smallest" scales every frame to the shortest height, so tops and bottoms line up and no photo is enlarged. "Keep original" leaves them alone and lines them up by top, middle or bottom instead — the tallest one then decides how tall the sheet is, and background shows above the others.
What this tool does not do
No free positioning: pictures go in a row, a column or a grid, and they never overlap. There are no frames or stickers, and captions are a separate step — add text after combining. A shared link carries the arrangement, not the photos; whoever opens it uploads their own.
