How to Combine Images into a PDF Online (Free, 2026)

Got a folder full of photos, screenshots, or scanned pages you need to send as a single document? Combining images into one PDF makes them easier to share, print, and archive. Here is how to do it for free in under a minute, no software install required.

Why combine images into a PDF?

There are a surprising number of everyday situations where you need this:

• Receipt management — photograph receipts with your phone, combine them by month for your accountant
• Passport and ID applications — combine photos of your documents into one PDF for visa or government applications
• School assignments — students combine handwritten homework photos into a single PDF to submit via LMS
• Property listings — real estate agents combine property photos into a presentable PDF brochure
• Medical records — combine photographed lab results, prescriptions, or reports
• Portfolio presentations — artists and designers combine work samples into a portfolio PDF
• Insurance claims — combine damage photos and supporting documents for easy submission
• Legal documentation — combine scanned evidence or exhibits for court filings

Method 1: Online converter (fastest)

The quickest way. Works on any device with a browser — phone, tablet, Mac, PC, or Chromebook. No account required.

1. Go to konomic.io/image-to-pdf
2. Upload your images by dragging them onto the page, or clicking "Browse" to select multiple files at once
3. Arrange the order — drag thumbnails to reorder pages
4. Click Convert to PDF
5. Download the combined PDF

Tip: you can upload up to 50 images at once on the free tier (up to 50 MB total). Each image becomes a page in the resulting PDF, in the order you arranged them.

Supported image formats

Konomic supports all common image formats:

• JPG / JPEG — the most common format, ideal for photos
• PNG — for screenshots and images with transparency
• HEIC / HEIF — iPhone default format (since iOS 11)
• WebP — modern web format, smaller than JPG
• BMP, TIFF, GIF — older formats, fully supported

You can mix formats in a single upload — Konomic will convert everything to a unified PDF automatically.

Method 2: Using your phone (iPhone)

iPhone has a built-in feature that combines photos into a PDF without any app install:

1. Open the Photos app and select the images you want
2. Tap the Share button (square with arrow)
3. Scroll down and tap Print
4. On the print preview, pinch outward with two fingers on one of the thumbnails
5. The print preview becomes a PDF — tap Share to save it

This works but has limitations: no ability to reorder pages, no compression, and the file size tends to be large. For anything more than a few images, Konomic is faster.

Method 3: Using your phone (Android)

Android has several ways, depending on your phone manufacturer:

1. Samsung Gallery: select photos → More → Create movie or PDF → Save as PDF
2. Google Photos: no built-in PDF export, but you can share to a third-party app
3. Files app: select images → Share → Print → Save as PDF

All of these work but are clunkier than using Konomic in a browser.

Method 4: Mac Preview

If you have a Mac, you can use Preview (no third-party install):

1. Select the images in Finder
2. Right-click → Open With → Preview
3. In Preview, show the sidebar (View → Thumbnails)
4. Drag to reorder if needed
5. Go to File → Print
6. In the print dialog, click the PDF dropdown → Save as PDF

Simple but limited — no compression, no orientation correction, no batch upload.

Method 5: Windows 10/11

Windows has a built-in "Microsoft Print to PDF" that works with images:

1. Select your images in File Explorer
2. Right-click → Print
3. Printer: Microsoft Print to PDF
4. Choose layout (full page, contact sheet, etc.)
5. Click Print → save as PDF

Works for basic needs but no reordering, no cropping, limited output quality options.

Tips for better results

• Rotate photos first — if your phone photos are sideways, fix the orientation before converting. Most gallery apps have a rotate option.
• Compress large images — if your images are huge (10+ MB each from a modern iPhone), the resulting PDF will be large too. Consider using Compress PDF afterwards or selecting "medium" quality during conversion.
• Add page numbers — for multi-page PDFs, use Page Numbers so recipients can reference specific pages.
• Watermark if needed — for copyright protection (portfolios, marketing materials), add a watermark with Add Watermark.
• Name the file clearly — "receipts_january_2026.pdf" is better than "document.pdf" for future retrieval.

What to do with the PDF after

Common follow-up tasks:

• Make it smaller for email: Compress PDF
• Password protect sensitive content: Protect PDF
• Make it searchable if it contains text: OCR
• Merge with existing PDFs: Merge PDF
• Reorder pages later: Reorder Pages

Frequently asked questions

How many images can I combine?

Free tier: up to 50 images per operation, 50 MB total. Pro: up to 200 images, 100 MB. Business: up to 500 images, 500 MB.

Will the image quality be preserved?

Yes. Konomic embeds images at their original quality by default. If you want smaller files, you can choose the medium or low quality option during conversion.

Can I reorder images before converting?

Yes. After upload, you can drag thumbnails to reorder before clicking Convert. The final PDF uses the order you set.

Can I add multiple images per page?

Not currently — each image becomes its own page. If you want a grid of images on one page, first combine them into a single image using a photo collage tool, then convert that to PDF.

Is it safe to upload my photos online?

With Konomic, yes. Files are encrypted in transit via SSL/TLS and automatically deleted from servers within 1 hour. We never use your files for AI training or share them with third parties.

Can I do this offline?

Konomic is browser-based and requires internet. For offline conversion, use your OS built-in tools (macOS Preview, Windows Print to PDF) or a desktop PDF editor.
