Stories, Reels, and TikTok
Switch to 9:16 for a vertical photo collage that fills a phone screen without awkward letterboxing.

Export 16:9 for presentation slides, YouTube visuals, newsletter headers, or a recap image for a launch post.
Frequently asked questions
Is this collage maker really free?
Yes. There is no account, no trial, and no watermark. Add up to 12 photos, arrange the grid, and download a full-resolution PNG as many times as you like.
Are my photos uploaded anywhere?
No. Photos are decoded and drawn on a canvas inside your browser, and nothing is sent to Launch Blitz. The PNG is rebuilt from pixels, so camera details and location data in the original files are not copied into the collage.
What size is the downloaded collage?
Square 1:1 collages export at 2160 x 2160 pixels, 4:5 portrait at 2160 x 2700, 9:16 stories at 2160 x 3840, and 16:9 landscape at 3840 x 2160. Those sizes downscale cleanly for Instagram, TikTok, Facebook, LinkedIn, and YouTube.
How are photos cropped to fit the grid?
Crop to fill scales each photo to cover its cell and trims evenly from the center. Show whole photo fits the entire image inside the cell and lets the background show around it. The preview uses the same math as the export.
What happens if my photos do not fill the grid?
Empty rows are removed so there are no blank bands. A partly filled last row is centered by default, or you can stretch those photos across the full width.
