Stitching Tips

  • Horizontal stitching is suitable for making long screenshots or panoramic images
  • Vertical stitching is suitable for making long Weibo posts or chat records
  • Grid stitching is suitable for making photo walls or product displays
  • Can adjust spacing to change the gap between images
  • Choosing appropriate background color can make the stitching effect more natural

How to Stitch Images Together Online?

  1. Upload multiple images in the order you want them to appear. You can rearrange them afterwards at any time, or use "Sort" and "Clear" to start fresh.
  2. Pick a stitching direction: horizontal lines everything up in a row, vertical stacks it into a column, and grid mode lays images out in rows and columns automatically (column count adjustable, default 3).
  3. Drag the slider to set the spacing between images, then choose a background color for the combined canvas.
  4. Choose the output format and quality, click "Start Stitching", and a single combined image is generated instantly — just download and save it.

Frequently Asked Questions

Can I mix images of different sizes?

Yes. Each image keeps its original size: in horizontal stitching the total width equals the sum of all widths and the height matches the tallest image, with the background filling any gaps — nothing gets distorted or cropped.

When should I use horizontal, vertical or grid?

Vertical suits long screenshots, comparison strips and chat logs; horizontal fits wide panoramas and banners; grid is tidiest for many similarly sized images (like product collages) and lets you set the column count freely.

Should I output JPEG, PNG or WebP?

JPEG is the versatile default with moderate file sizes. PNG is fully lossless with crisp edges, ideal for stitched screenshots containing text. WebP gives the smallest files at comparable quality — great for the web. The quality slider fine-tunes size further.

Does stitching degrade quality?

No resampling means no loss — every image is placed at its original pixels. Only lossy outputs like JPEG are affected by the quality setting; choose PNG for absolutely lossless results.

Are my images uploaded to a server?

No. Stitching happens entirely locally in your browser, so your images never leave your device.

Does it work on mobile?

Yes. The page is optimized for mobile browsers — upload and stitch right from your phone.
