Merge images online
Join several pictures into one, see the result before you save it, and download it as PNG, JPEG or WebP. It all runs in your browser.
- Three ways to arrange. Put pictures side by side, stacked in a column, or in a grid with the number of columns you pick. The preview updates as you change anything.
- Set the order. Tap a thumbnail, then use Move earlier and Move later to change its place. Remove one with the bin button.
- Match or keep sizes. Match sizes scales every picture to line up evenly without stretching it. Keep sizes leaves each one as it is and centers it.
- Gap and background. Add a gap from 0 to 200 pixels between pictures and choose the background color, or leave it transparent for PNG and WebP.
- PNG, JPEG or WebP. Save the result in the format you need, and set the quality for JPEG and WebP. PNG keeps every pixel.
- Up to 50 images. Drop or paste a whole set at once. Everything runs in your browser, so your pictures are never uploaded.
Uses of merging images
- Before and after. Put two versions of a photo or a design next to each other to show a change clearly.
- Collages. Build a quick grid of photos for a post, a card or a family message without opening a design app.
- Long screenshots. Stack several screenshots into one tall picture so a whole page or chat fits in a single file.
- Product comparisons. Line up product photos with a small gap and a white background to compare them at a glance.
- Scanned pages. Join the front and back of a document, or several scanned pages, into one image to send or archive.
Merge images questions
How do I merge images online?
Add two or more pictures, choose side by side, stacked or grid, set the order, then choose Download. The merge happens in your browser, so nothing is uploaded.
Can I change the order of the images?
Yes. Tap a thumbnail to select it, then use Move earlier or Move later. The preview and the saved picture follow that order.
What is the difference between Match sizes and Keep sizes?
Match sizes scales the pictures to the same height (side by side), width (stacked) or cell size (grid), without stretching. Keep sizes leaves every picture at its own size and centers it, so there may be empty space around smaller ones.
Will merging lower the quality?
PNG keeps every pixel. Match sizes can shrink larger pictures to the size of the smallest one, so for the sharpest result use pictures of similar size or choose Keep sizes.
Can I keep a transparent background?
Yes, choose Transparent and save as PNG or WebP. JPEG has no transparency, so it fills the background with white.
Is there a size limit?
Browsers stop at 16384 pixels on a side and about 120 million pixels in total. If the result would be bigger, the tool tells you and you can use fewer images or a smaller gap.
Is my image uploaded anywhere?
No. Everything runs in your browser on your own device. Your images are never sent to a server.
