How to Combine Images Online in 3 Easy Steps
No software, no registration just upload, choose, and download. Works on any device in under a minute.
Upload Your Photos
Click any slot to add your images. You need at least 2 photos to combine. Slots 3 and 4 are optional. Supports JPG, PNG, and WebP files up to 15 MB each. If your photos are too large, compress them first to keep things fast.
Choose Layout and Settings
Pick horizontal (side by side), vertical (stacked), or 2×2 grid. Adjust gap size, gap colour, output format (JPG or PNG), quality, and max width. For best alignment results, crop your photos to the same aspect ratio before uploading.
Combine and Download
Click Combine Images your merged photo appears instantly in the preview. Download it with one click. No watermarks, no hidden costs, no email required. The result is ready to share, upload or print straight away.
Which Layout Should You Choose?
Pro tip: If your images have different aspect ratios, the tool automatically scales them to fit the chosen layout. For pixel-perfect alignment, use the free Image Cropper first to unify dimensions. Set gap to 0px for a seamless join especially useful for stitching screenshots together.
Why This Free Image Combiner Stands Out
Clean, fast and 100% private everything you actually need in an image merging tool.
Merge 2 to 4 Photos
Combine 2, 3 or 4 images in one session. Only the slots you fill are used no need to pad with blank images.
3 Flexible Layouts
Side by side, vertical stack, or 2×2 grid. Each layout scales your images automatically to fit neatly.
Custom Gap Colour
Choose any colour for the gap between images white, black, your brand colour, or full transparency.
Adjustable Gap Size
From 0 px (seamless stitch) to 40 px (clearly separated). Ideal for both collages and technical side-by-side merges.
JPG or PNG Output
JPG gives smaller files for sharing and email. PNG preserves transparency useful for logos and design files. You can also convert AVIF to JPG first if your phone saved photos in AVIF format.
Quality and Resize Control
Set JPG quality from 60% to 100% and choose a max output width. Use our Image Compressor after combining for even smaller files.
100% Private No Uploads
Your images never leave your device. All processing happens inside your browser using the HTML5 Canvas API completely offline once the page has loaded.
Works on Any Device
iPhone, Android, iPad, Windows, Mac just open in Chrome, Safari, Firefox or Edge. No app to install, no account required.
Instant Live Preview
See your combined image immediately after clicking Combine no waiting, no page reloads, no surprises before downloading.
Popular Real-World Uses
Image Combiner vs Collage Maker Which One Do You Need?
Image Combiner (This Tool)
Pure grid merging with no decorations, no text overlays and no watermarks. Best when you need a clean, professional result:
- Before and after comparisons
- Product specification sheets
- Screenshot stitching for tutorials
- Invoice or document merging
- E-commerce multi-angle product images
Collage Maker (Alternative)
Adds frames, stickers, text overlays and artistic backgrounds. Slower to use, often adds watermarks, and not ideal for professional or technical work. Better suited for:
- Scrapbook-style memory pages
- Birthday and greeting cards
- Social media stories with effects
- Personal art and hobby projects
Why Use an Online Image Combiner Instead of Photoshop?
Photoshop is powerful but it is overkill for simple merging. It costs money, has a steep learning curve and requires installation. This free image combiner does the same job in under a minute no account, no watermark, no uploads needed.
Everything runs locally in your browser using the HTML5 Canvas API, which means your images never leave your device. You can even use it during internet outages once the page has loaded. For very large images, the Max Width setting keeps output files manageable 800px is great for web and social, while 1920px suits print and high-resolution archiving. If you need to enlarge small images before combining, try our free AI Image Upscaler first.
Preparing Your Photos for the Best Results
The image combiner works with any photos straight from your phone or computer, but a little preparation makes a big difference in the final result.
If your photos have different dimensions, the tool scales them automatically but for pixel-perfect alignment in side-by-side layouts, crop each photo to the same aspect ratio first. If you have photos saved in AVIF format (common on iPhone and newer Android phones), convert them to JPG using our free AVIF to JPG Converter before uploading. Similarly, if you have WebP files, convert WebP to JPG first. For oversized photos that slow down the preview, run them through the Image Compressor to reduce file size without visible quality loss.
Using the Image Combiner on iPhone and Android
Open this page in Safari on iPhone or Chrome on Android. Tap any slot to add images from your camera roll or Files app. Choose your layout and settings, then tap Combine. The merged image appears in the preview tap Download to save it directly to your Photos (iOS) or Gallery (Android). No app to install and no account required.
Troubleshooting: If a photo does not load, check that it is in JPG, PNG or WebP format and under 15 MB. For very large images, reduce Max Width to 800px before combining. If your photos are in AVIF format from your iPhone camera, use our AVIF to JPG Converter first. If images appear sideways, rotate them online before uploading to the combiner.
What Image Formats Can I Combine?
The image combiner accepts JPG, PNG and WebP files. If your photos are in a different format, use one of these free converters first: AVIF to JPG, WebP to JPG, JFIF to JPG, or JPG to PNG. All converters are free, instant and work entirely in your browser no uploads, no watermarks.
For the output, choose JPG when you need the smallest file size for sharing, emailing or uploading to social media. Choose PNG when your images contain transparency for example logos or cutouts produced by the Background Remover.

How do I stitch screenshots together seamlessly?

What is the maximum file size per image?
15 MB per image. If your photos are larger, use our free Image Compressor first to reduce file size without any visible quality loss then upload to the combiner.
Can I keep a transparent background when merging?
Yes choose PNG as your output format. PNG supports transparency, so the gap areas remain transparent if you set the gap colour to transparent. JPG does not support transparency and will fill gaps with white. If you need to remove a background from a photo before merging, use our AI Background Remover first.
What quality setting is best for Instagram?
Set Max Width to 1080px and quality to 92% that matches Instagram's native resolution and upload compression. For Stories (vertical format), use the Vertical Stack layout. For feed posts or carousels, use Side by Side or 2×2 Grid.
