Need to turn three screenshots into one tall image, or put two photos side by side? You don't need Photoshop, and you don't need to create an account on some upload service. Waripixel's free Image Stitch tool does it in your browser in about thirty seconds.
The 30-second version
Open waripixel.com/stitch, drop in two or more images, pick Horizontal (side by side) or Vertical (stacked), and click Download stitched image. That's genuinely all of it — no signup, no watermark, no file limit games.
Why "match sizes" matters
The most common problem when combining images is mismatched dimensions: a 4000-pixel photo next to a 1200-pixel screenshot looks broken. Image Stitch's Match sizes mode scales every image to a common height (for horizontal strips) or width (for vertical stacks). It only ever scales down, never up, so nothing gets blurry. If you want a scrapbook look instead, switch to Keep original and choose start, center, or end alignment.
Spacing, backgrounds, and formats
A spacing slider adds a clean gap between images (0–200 px), and the background behind those gaps can be any color — or fully transparent if you export PNG or WebP. JPEG exports get the background color automatically, since JPEG doesn't support transparency. A live preview shows the exact output, including its final pixel dimensions.
Your images never leave your device
Unlike most "merge images online" sites, Image Stitch is fully client-side: the stitching happens in your browser's canvas, and nothing is uploaded anywhere. That makes it safe for unreleased product shots, client work, or anything under NDA — and it's why it stays fast even with large photos.
