Repeat a photo as a tile

What you get back

The page opens at 3 rows, 3 columns, and scale 1. Export PNG is named photo-tile- plus a timestamp. One file, not a ZIP. Rotate and flip happen before the repeat, so a 90 degree turn swaps width and height and then that rectangle is copied.

Output width is photo width × columns × scale. Output height is photo height × rows × scale. A 1000×1000 photo at 10×10 and scale 1 is 10000×10000. Scale 2 on that same grid is 20000×20000. Scale 5 is 50000×50000. A large grid can fail in the tab because the canvas is that many pixels. Start at scale 1 and a small count, then raise one of them.

Setups that match a job

Seams are the point of the limit

There is no blend control, no offset, and no mirror mode. The cell is drawn, then drawn again beside it. A portrait, a snapshot, or a logo with a plain margin will show a grid of edges. That can be what you want. It is not a failure of the export.

If you need several different photos in one frame, this is the wrong tool. Photo tile has one source. The collage puts a different photo in each cell and writes one PNG. Split photo cuts one photo into a ZIP. Which tool is the short page for that choice.

A safe way to export

1. Upload the photo. The button says Upload Photo. The page names JPEG, PNG, and WebP.
2. Set rows and columns. The sliders stop at 20. The labels are Rows and Columns.
3. Leave Scale at 1. Look at the output size the page shows before you raise it.
4. Press Export PNG. If the tab stalls, lower the count or the scale and export again. The tool does not queue a server job. Closing the tab drops the photo.
5. Do not expect the collage to import the tile settings. If the tiled PNG should sit inside a collage, export first, then upload that PNG on the collage page.

The preview is not the file

The preview fits the repeated grid into a box of about 1200 pixels on the long side. It uses the row count and the column count. It does not apply Scale. Scale 1 and scale 5 can look the same on screen. The PNG does not. Scale 5 multiplies both the width and the height of the export by 5.

Read the output size on the page before you press Export PNG. That line is photo width times columns times scale, by photo height times rows times scale. If it says something like 10000×10000, that is the file, not the preview. A laptop can fail to allocate a canvas that large. Lower Scale back to 1, or lower the count, and export again.

The preview canvas is created with alpha turned off, then filled white, then the tiles are drawn. That white belongs to the preview. Export builds a second canvas. It clears the pixels and draws the tiles. It does not paint the white fill. A PNG from a photo that already has transparent pixels can keep them. Judge the file, not the white box on the page.

A 1×1 grid at scale 1 writes the photo once, as one PNG. Scale moves in steps of 0.1 and cannot go below 0.1. Scale 0.1 on a 4000 pixel wide photo makes each cell 400 pixels wide. Columns then multiply that width. A 1×10 grid at scale 0.1 is a strip of ten small copies, not a 10× enlargement.
