How-to Guide
Merge JPG Images into a PNG Grid Online
JPG is great for individual photos, but combining multiple JPGs into a grid and saving as JPG doubles the compression. Exporting as PNG preserves every pixel.
Try MergeFrame — FreeJPG compression is lossy — every save loses data. Traditional editors re-compress combined images, creating twice-degraded output. MergeFrame exports as lossless PNG: source JPGs are loaded at original quality, composited at full resolution, and exported without generation loss.
Critical for: (1) e-commerce product grids — color accuracy drives purchases, (2) real estate photos — detail preservation matters, (3) text screenshots — JPG creates fuzzy characters, (4) any grid that will be edited or zoomed.
Also supports WebP input — convert WebP images into PNG grids without format issues.

Frequently Asked Questions
Why PNG instead of JPG?
PNG is lossless — every pixel preserved. JPG re-compresses and creates visible quality loss at grid boundaries.
Will PNG be much larger?
Yes, 2–5× larger. Optimize after export with TinyPNG for web. Keep full PNG for print.
Can I combine mixed formats?
Yes. JPG + PNG + WebP in one grid — export is always lossless PNG.
