Merge Images
Combine multiple images with preset layouts in your browser. Preview side-by-side and stacked compositions instantly, set an optional colored gap, pick PNG, JPG, or WebP, then download—without uploading photos to a collage server for the basic merge path.
Merge Images Features
100% Client-Side Processing
All merging happens locally in your browser. Your images never leave your device, so privacy and security stay intact.
Horizontal and vertical layouts
Merge images side-by-side (horizontal) or stacked (vertical), reorder selections, and preview the collage before you download.
Live Preview
See the merged result in real time before downloading. Adjust layout and export settings to fit your needs.
PNG/JPG/WebP Output
Export your merged image as PNG or JPG, or choose WebP for modern compression with excellent quality-to-size ratio.
Fast and Lightweight
Powered by the Canvas API with optimized drawing. Instant merges without server roundtrips.
Cross-Platform
Works on Windows, Mac, Linux, iOS, and Android. Use it directly in any modern web browser.
How to Use Merge Images
Select Images
Click "Choose Images" to select one or more image files from your device. All processing happens locally in your browser for maximum privacy.
Choose a Layout
Pick side-by-side (horizontal) for comparisons that read left-to-right, or stacked (vertical) for step sequences. Reorder thumbnails until the story order feels right; the preview updates as you change layout and gap.
Select Output Format
Choose PNG/JPG/WebP. Optionally set the export size and add a colored gap between images. Then click download to save your merged image.
Why merge in the browser instead of a full editor
A collage tool for small jobs, not a replacement for Photoshop
Merge Images is for the moments when you already have two or three finished frames and only need them in one file: a before/after strip for a contractor, a vertical stack of UI screenshots for a bug ticket, or a marketplace listing that accepts a single hero upload. You choose files, pick horizontal or vertical layout, optionally add a gap, and export. There is no account wall for the core flow.
Because drawing happens with the Canvas API on your device, you can keep sensitive screenshots off third-party upload converters. If you later need freeform layers, blend modes, or typography-heavy posters, move the PNG into a full editor—this page stays intentionally narrow so the merge stays fast.
Reordering thumbnails before export matters more than people expect: put the “after” photo on the right for western reading order, or stack steps top-to-bottom for procedural docs. Lock aspect ratio when resizing exports so a tall phone screenshot does not squash beside a wide desktop capture.
Choosing PNG, JPG, or WebP for the destination
PNG keeps sharp UI edges and transparency when you need a clean composite for documentation. JPG usually shrinks photographic merges for chat or email. WebP often wins when the destination supports it and you want a modern size/quality tradeoff. Preview first at 100% zoom on at least one source so you notice clipping before you send the file.
Very large camera originals can stress mobile browsers. If the preview stalls, downscale sources once, then merge. Desktop Chrome or Firefox typically handles multi-megapixel strips more comfortably than a low-memory phone tab.
Layouts people actually ship
Before/after comparisons
Place two photos side by side for renovations, design revisions, or progress shots you can share as one file.
Screenshot collages
Stack UI captures vertically to document a multi-step flow in a bug report or tutorial.
Social and marketplace listings
Combine product angles into a single image when a platform accepts one hero upload.
Quick moodboards
Assemble reference images without opening a full desktop editor for a simple strip layout.
Support tickets with two states
Attach one horizontal strip showing the broken UI next to the expected state so agents do not hunt through a zip of screenshots.
Classroom or workshop handouts
Stack three process photos vertically for a one-page PDF insert without opening a layout program.
Where your collage files stay
Collage bytes stay on the device for the core export
Merge Images reads the files you select and draws them with the Canvas API in your browser. The merged PNG, JPG, or WebP download is generated locally for the standard layout path.
That makes the tool suitable for screenshots or photos you are not ready to upload to a cloud collage service. Clear the selection when you finish on a shared computer, the same way you would close any private image tab.
Site-level advertising scripts on tool pages (when enabled) are separate from this canvas pipeline; they do not receive your image bytes as part of the merge.
What this merger deliberately skips
Preset layouts only
Current layouts focus on side-by-side and stacked compositions. Freeform layers, masks, and blend modes belong in a full editor.
Memory limits on phones
Very large camera originals may strain mobile browsers. Resize huge sources first if preview stalls.
No cloud project files
There is no multi-device project sync. Re-select images if you move to another computer.
Merge Images FAQ
It combines multiple images into one downloadable file using preset layouts such as side-by-side or stacked. Processing runs in your browser with a live preview.
Yes. You can select images, preview layouts, and download PNG, JPG, or WebP without paying for the basic merge workflow.
No. Selection, preview, and export use client-side canvas drawing. Files stay on your device for this tool's core flow.
PNG for maximum fidelity, JPG for smaller photos, and WebP for modern compression. Pick based on where you will upload the result.
Yes. You can set a gap width and gap color so stacked or side-by-side merges read more clearly.
Side-by-side (horizontal) and stacked (vertical) presets. You can reorder images, set a gap and gap color, choose PNG/JPG/WebP, and optionally resize the export while keeping aspect ratio.
Desktop and mobile browsers that support the Canvas API. Desktop usually handles large merges more comfortably.
Yes. Add as many files as your browser can comfortably draw, then reorder thumbnails before choosing side-by-side or stacked layout.
The merger aligns images in the chosen orientation and can resize the final export while optionally locking aspect ratio. Extreme mismatches may leave uneven edges—crop sources first if you need a perfect rectangle.
