How this tool works
What it does
Collage Maker arranges images into a grid collage.
Layout
Columns, square cell size and gap; cover/contain fit.
Robust
Skips and lists bad files; needs 2+ valid images.
Privacy & metadata
Everything runs in your browser on a canvas — your image is never uploaded. Browser canvas export strips EXIF, GPS, and most other source metadata.
Collage Maker in your browser
Collage Maker arranges several images into a grid collage in your browser. Everything runs in your browser on a canvas — your image is never uploaded. Upload your images, choose the number of columns, cell size and gap, pick a fit mode and background, and export as PNG, JPG, or WebP.
Each file is checked and decoded individually — an unsupported or oversized file is skipped and listed rather than breaking the whole collage, which is built as long as at least two valid images remain. Cells can crop to fill (cover) or fit the whole image with padding (contain).
Collage Maker shows the grid layout, the number of images placed, any skipped files, the output dimensions and the file size. Browser canvas export strips EXIF, GPS, and most other source metadata. Animated GIFs are processed as a single still frame; animation is not preserved.
