Why it matters
Nothing is uploaded
The pictures are put together in your browser. Private photos, client work and documents never leave your computer.
Edges that line up
Pictures are scaled to one height side by side, one width stacked, or one cell in a grid, so the result looks planned, not pasted. The page warns when that would enlarge a small picture enough to blur it.
Your order, your spacing
Reorder with a tap, sort by name, set the gap and the border in pixels, pick a background colour or keep it transparent.
Questions
How do I merge PNG images into one PDF?
Drop the PNGs in, set the order, set Save as to PDF, and download a one-page PDF of the merged picture. For one picture per page, use combine images to PDF.
Will merging keep transparency?
Yes, when you save as PNG. A PDF or JPG has a white background.
How many pictures can I merge?
Up to 120 at once. A merged picture larger than a browser can draw (about 16,000 pixels on a side) is scaled down to fit, and the page says by how much; a PDF with a page per picture keeps every pixel however many there are.
Will my pictures lose quality?
PNG output is lossless. Pictures are only scaled when you ask for sizes to be matched; "Match sizes: smallest" shrinks the larger ones rather than enlarging the smaller, and "Keep original sizes" leaves every pixel as it is.
Can I make a grid of pictures?
Yes. Pick a grid by its rows and columns: 2 × 2 for four squares, 1 × 2, 3 × 1, 2 × 3, 3 × 3 and more up to 5 × 5, or Auto-fit for the number of photos you have. A fixed grid keeps its empty cells, and adds rows rather than leave a photo out. Then the cell shape: square, 4:3, 16:9 and others, or the shape your pictures have. "Fit, trimming only empty edges", the default, fills each cell by trimming a picture’s plain background and never cuts into what is on it; "Whole picture" leaves every picture as it is; "Fill" trims every picture to its cell, content included.
Can I make a collage, with one big picture?
Yes. "Big + 2" and "Big + 3" put one large picture beside smaller ones, "Big top" puts it above them, and "Big centre" surrounds it with six. With more pictures than the style holds it repeats down the page. The first picture in your list is the big one, so move the one you want to the top.
What is the mosaic style?
Rows of pictures at their own shapes, nothing cropped, each row stretched to the same width, the way photo galleries lay out mixed portrait and landscape photos.
Can I turn the merged picture into a DXF or SVG?
Yes: "Trace to DXF" hands the merged picture to the tracer, which turns it into lines and shapes you can size in millimetres for a laser, CNC or cutting machine. A DXF is drawn geometry, not a photo, so this suits logos, line art and silhouettes rather than photographs.
Can I combine the pictures into a PDF?
Yes. Choose PDF as the output for the merged picture on one page, or the "PDF, a page per picture" layout to put each picture on its own page.
