Output dimensions appear after you select images.
Continue your task
Reduce the combined image size before sending it. Open Image Compressor.
Choose the layout from the reading order
Use a vertical strip for a sequence read from top to bottom, horizontal for a small side-by-side comparison, or a grid for a compact overview. Check that small screenshot text remains readable at the final display size.
Know when PDF is a better container
A long image can become difficult to read or print. Use JPG to PDF when each screenshot should occupy a separate document page. Use Image Resizer when a destination imposes pixel dimensions on a combined image.
Check the final edge and background
The exported canvas should not add outer white bands above or below the complete composition. A shorter image in a horizontal row or grid can still leave background inside that row; this is different from extra canvas padding. Check the first and last pixels of a vertical strip, then inspect any gaps created by mixing portrait and landscape sources.
If the download shows more empty space than expected, set spacing to zero, try a vertical layout for mixed heights, and check the output dimensions before exporting. Very tall strips may be awkward on phones; use JPG to PDF when each picture should be a separate page.
Compare image layouts before downloading
With three 480 × 320 images and a 12 px gap, vertical output is 480 × 984 px; horizontal is 1464 × 320 px; grid is 972 × 652 px. Grid rows fit the scaled images without adding outer top or bottom margins. Different aspect ratios can leave space below shorter images within a row. The tool displays your actual output dimensions above.
Download the input images and outputs. See before-and-after examples for all three layouts, including exact sizing rules and JPG/PNG choices.
About JPG Combiner
This tool exports one raster image from JPG, JPEG or PNG inputs. Choose vertical for a sequence of screenshots, horizontal for a two-image comparison, or grid for a compact overview. It does not create a multi-page PDF; use JPG to PDF for that output.
How to combine JPG files
- Select two or more images.
- Choose vertical, horizontal or grid layout.
- Set spacing and background options.
- Preview the result, then select Combine Images to download one image.
When an image combiner is useful
- Combine screenshots into one shareable image.
- Join several JPG files into one long image for documentation.
- Create a simple before-and-after comparison using a horizontal layout.
- Place product or project images into a clean grid.
- Combine scanned pages when a single image is more convenient than multiple files.
JPG merge vs JPG to PDF
If you need one image file, use this JPG combiner. If you need a document with separate pages, use JPG to PDF. For a printable document, PDF is often easier to paginate and share; for a quick visual collage or image strip, combining JPG files into one image is usually simpler.
Privacy and file handling
Images are read and combined in your browser. ToolVero does not upload them to a ToolVero processing server. Your selected images remain in the browser workflow unless your own page or browser extension introduces another network operation.
Things to know before combining images
Large images can consume significant browser memory. Combining images also creates a new raster image, so very large outputs may be slower to download or open. Keep the originals when image quality matters.
Frequently asked questions
Can I merge JPG files online for free?
Yes. ToolVero can combine multiple JPG, JPEG and PNG images into one downloadable image without an account.
Can I combine JPEG files into one image?
Yes. JPEG and JPG are accepted as the same image family in this tool. You can combine them vertically, horizontally or in a grid.
Does combining JPGs reduce quality?
PNG output preserves lossless image encoding. JPG output uses adjustable JPEG quality and may introduce normal JPEG compression.

Example: join two screenshots vertically
Add your first screenshot, then add the second. Check that both remain selected. Choose Vertical, use zero spacing for a continuous strip, and choose PNG for crisp interface text. Preview the order before downloading.
Use Horizontal for a before-and-after comparison and Grid for a group of product images. A vertical result can be much taller than either input. If an upload portal rejects the dimensions, use Image Resizer and check that text remains readable. PNG avoids another JPEG encoding step, but resizing can still change image detail.
For separate printable pages, use JPG to PDF instead.
