Combine photos, graphics, and screenshots into one image.
Merge Images combines multiple pictures into one continuous image. Arrange JPG, PNG, WebP, AVIF, BMP, GIF, HEIC, or HEIF files in the order you want, then join them as a vertical stack, horizontal strip, or grid. It works well as a screenshot stitcher, photo collage maker, before-and-after image builder, and simple product comparison tool.
Vertical layout is useful for long screenshots, chat captures, web page sections, receipts, tutorials, and step-by-step instructions. Horizontal layout works well for panoramas, side-by-side comparisons, sprite references, and progress photos. Grid layout can combine thumbnails, contact sheets, mood boards, listings, and social media images.
Keep original sizes when every image should retain its exact pixel dimensions. Match the first or largest image to align mixed-size screenshots and photos while preserving each image's aspect ratio. You can also control the gap, outer padding, alignment, background color, transparency, output scale, image format, and compression quality.
All image decoding, layout, preview, and export work happens locally in your browser. Files are not uploaded to a server. For very large screenshot sets, choose a smaller output scale to reduce memory use and keep the final canvas within browser limits.
Choose the vertical layout, order screenshots from top to bottom, and use zero or small spacing. Keep original size when all captures share the same width.
Keep original size preserves each image. Fit, fill, and stretch modes scale images differently inside the calculated cells, while alignment controls where extra space appears.
Yes, when PNG or WebP is selected. JPEG does not support transparency, so a solid background is used.
The final canvas must fit in browser memory. Many large images or a very long combined result may exceed the memory available on the device.
