100% Private — No Upload to Any Server

Merge Unlimited Files — JPG, PNG, WebP, HEIC

Guides & Tips

How to Merge JPG Files Into One Image (Step by Step)

Merging JPG files is the most common image combining task — combining photos, creating before/after comparisons, or stitching screenshots into one long JPG. Here is the fastest way to do it without installing software:

  1. Open this page on any browser — desktop or mobile. No account or app download needed.
  2. Upload your JPG files — drag them onto the upload area or click to browse. Upload order sets the left-to-right or top-to-bottom sequence.
  3. Choose a layout: Horizontal for side-by-side (great for comparisons), Vertical for stacking into a long image (great for screenshots), Grid for photo collages.
  4. Click Merge & Download — get a single JPG, PNG, or WebP file in seconds.

JPG vs PNG output when merging JPGs: If your source files are JPG photos and you want the smallest output file, export as JPG. If you are stitching screenshots end-to-end and want to avoid compression artifacts at the join line, export as PNG instead — it is lossless and keeps the seam invisible.

You can also merge a mix of JPG and PNG files in one operation — no pre-conversion required. The tool handles format differences automatically.

How to Put Two Pictures Side by Side (or Combine More Than Two)

Putting two pictures side by side is the most common merge use case — for before/after comparisons, product shots, or sharing two moments in one image. Here is how to do it:

  1. Upload both images — drag them onto the upload area. Order matters: the left image goes first.
  2. Select Horizontal layout — this places images next to each other left-to-right in a single row.
  3. Download — click Merge & Download to save the combined image as JPG, PNG, or WebP.

If your two photos have different heights, the tool automatically scales both to the same height so they align cleanly. You can also add a gap using the Spacing control — useful for a visible white or black dividing line between the two images.

Need to put more than two pictures together? Upload all of them and drag thumbnails to set the sequence. For four or more images, try Grid mode — it arranges them automatically in balanced rows and columns.

Merge JPG, JPEG, PNG — Format Guide for Combining Images

When merging images, the input format and output format are independent choices. Here is what to pick for common scenarios:

ScenarioInputRecommended OutputReason
Photo collage / comparisonJPG or JPEGJPGSmallest file size, good enough quality for photos
Screenshot stitchingPNG or JPG screenshotsPNGLossless — no compression artifact at the seam
Web use / social sharingAnyWebPBest quality-to-size ratio for web platforms
Mixing JPG + PNGBothPNG or JPGTool handles mixed formats automatically — pick output based on use case
HEIC (iPhone photos)HEICJPG or PNGHEIC is supported as input; output converts to standard format

JPEG vs JPG: These are the same format — .jpg and .jpeg are interchangeable file extensions. A JPEG merger and a JPG merger do the same thing.

PNG merger note: PNG files can have transparent backgrounds. When merging PNGs with transparency, set your background color to white (or any solid color) to fill transparent areas, or keep it transparent and export as PNG to preserve it.

What Is Image Stitching? (And When to Use Vertical Merge)

Image stitching means joining multiple images together — usually vertically — to form one long continuous image. The most common real-world use cases:

  • Screenshot stitching: Take 3–5 screenshots scrolling through a webpage or chat conversation. Stitch them top-to-bottom into one tall image so the recipient can read everything without receiving multiple files.
  • Step-by-step instruction strips: Each step in a tutorial is one photo; stacking them vertically creates a readable how-to strip for social media or documentation.
  • Product detail strips: E-commerce sellers combine multiple angle shots into a single tall image for platforms that favor one-image previews.

To stitch images vertically: upload all images, select Vertical layout, set spacing to 0 for seamless join, then download as PNG for a clean seam. Images are automatically scaled to the same width.

Looking for a PineTools Merge Image Alternative?

If you found this page while looking for PineTools merge image or a PineTools alternative, here is a quick comparison of what is different:

PineTools is a well-known image utility that supports merging two images side by side or vertically. It works for simple one-off tasks. The main functional differences with BulkPicTools:

  • File count: PineTools supports exactly 2 images per merge. BulkPicTools has no limit — merge 2, 10, or 50+ images in a single operation.
  • Privacy: PineTools uploads your files to their server for processing. BulkPicTools runs entirely inside your browser — files never leave your device, and the tool works offline.
  • Output formats: PineTools outputs JPG or PNG. BulkPicTools adds WebP output and lets you control quality, spacing, and background color independently.

If you only need to combine two images quickly, PineTools does the job. If you need batch merging, local processing, or more output control, BulkPicTools is built for that use case.

Also worth noting: if you use PineTools for rounding image corners, BulkPicTools has a dedicated Round Corners tool that runs the same way — locally in your browser, no upload, no limit.

How to Combine Photos on iPhone or Android (Without Downloading an App)

iPhone's built-in Photos app does not have a native merge or side-by-side feature. The browser method requires no app download:

  1. Open Safari on iPhone (or Chrome on Android) and go to BulkPicTools.com
  2. Tap the upload area and select photos from your Camera Roll — you can select multiple at once

  4. Tap Merge & Download — the combined image saves to your Downloads folder

Works on any iPhone with iOS 15+ and any Android with Chrome. No account, no app download, no watermark.
