Make a photo grid collage

From an empty canvas to a file

1. Open the collage. The layout is already 4 Photos (Grid), a 2×2. Spacing, Outer Margin, and Roundness each start at 1%. The background is white, #ffffff.
2. Pick a size before you fuss with the pictures. Square is 1200×1200. IG Portrait is 1080×1350. IG Story is 1080×1920. FB Post is 1200×630. FB Cover is 1920×721. Or type Width and Height. The fields override the button. For a feed size Instagram's help page names exactly, use the Instagram sizes page. 1080×1080 is a typed size, not the Square button.
3. Click a layout button if 2×2 is wrong. The six buttons are 1 Photo, 2 Photos (V), 2 Photos (H), 4 Photos (Grid), 1+2 Mixed (H), and 2+1 Mixed (V). What each one does is on the layouts page. For any other count, set Rows, then the cells in that row. Rows stop at 10. Each row stops at 5 cells.
4. Upload a photo into each cell. The file input accepts an image. The page names JPEG, PNG, and WebP. Drag inside the cell to reframe. Rotate and flip act on that cell, not on the whole collage.
5. Set Spacing and Outer Margin. Both are a percent of the shorter canvas side, from 0% to 20%. They start at 1%, so the cells have a hairline gap until you move Spacing to 0. Roundness runs from 0% to 50% of the shorter side of that cell. Background Color is the hex shown next to the swatch.
6. Press Export PNG. The download is collage- plus a timestamp, and the pixel size is the width and height on the size control. A 1080×1350 canvas does not become a 1200×1200 file.

Layout buttons

What this page will not do

A collage joins photos. It does not cut one photo into nine posting tiles. That is split photo, and the ZIP is a different download. If you export a collage and then want a 3×3 profile puzzle, open split photo and upload the PNG you just saved. The collage page will not slice it.

Brightness, contrast, and saturation are not on this page. Those sliders live on the brightness tool, from 0% to 200%, and 100% means unchanged. Export that PNG, then upload it here. Closing the other tab does not apply the sliders.

There is no account, no watermark, and no server copy of the photo. The file exists in this tab until you export it or close the tab. Google Analytics on the site counts the visit. It does not receive the image. The privacy policy states that, and it also states that no advertising script is loaded.

A 2×2 that is actually square

Leave the layout on 4 Photos (Grid). Set Width and Height to 1080 and 1080 if you want the width the Instagram help page uses as its ceiling. Move Spacing to 0 if the photos should touch. Outer Margin at 0 uses the whole canvas. Export PNG. You get one 1080×1080 file, not four files.

If the four photos should be four posts, you are in the wrong tool. Split photo at 2 rows and 2 columns writes four PNGs named split_1_1.png, split_1_2.png, split_2_1.png, and split_2_2.png. The collage writes one file.
