Frequently asked questions
Is StitchPic free to use?
Yes. StitchPic is completely free to merge and download images, with no account required and no watermark.
Are my images uploaded to a server?
No. Everything runs locally in your browser. Your images never leave your device, which keeps them fully private.
How many images can I merge at once?
You can merge between 2 and 30 images in a single combined image, arranged either horizontally or vertically.
Why is there white space around a smaller image?
When images have different sizes and you choose “Do not adjust,” the canvas matches the largest image, so smaller ones are centered with the background color filling the gap. Choose a resize option like “Reduce biggest” or “Magnify smallest” to make them the same size and remove the space.
What file formats are supported?
You can upload common image formats such as JPG, PNG, WebP, and GIF. The merged result is downloaded as a high-quality PNG.
