How to Merge Images Without Losing Quality
Learn how to merge images without losing quality. Use the right layout, canvas size, and export format for a sharper combined photo.
Image quality usually drops when a tool resizes or repeatedly compresses your files. The best workflow is to use the original images, avoid unnecessary resizing, and export once.
A quality-first workflow
- Start with the highest-resolution versions of your images.
- Choose a canvas ratio that does not crop important content.
- Avoid stretching one image to match another unless necessary.
- Export once in PNG when text or sharp edges matter.
PNG or JPEG?
| Image type | Better default |

| Screenshots, text, logos | PNG |
| Photos and large albums | High-quality JPEG |
| Transparent graphics | PNG |
