The Images to PDF tool combines multiple images (JPG, PNG, WebP, GIF, BMP) into a single PDF document with each image as its own page. Perfect for creating photo albums, compiling scanned documents, building portfolios, or making photo books. Unlike the Image to PDF tool that may handle one image, this is optimized for multi-image workflows with reordering, page-size control, and margin adjustment.

Upload multiple images at once, drag to reorder, configure page size (A4, Letter, custom) and layout options (fit, fill, actual size), and download the combined PDF. Each image becomes one page by default. All processing runs in your browser so images and resulting PDFs stay local. Great for home and professional use where you need to bundle photos or scanned pages into a distributable document.

Technical details

This tool is functionally similar to Image to PDF but optimized for batch workflows with visual reordering.

Generation process using jsPDF or pdf-lib:
1. Collect all uploaded images
2. Let user reorder via drag-and-drop thumbnails
3. For each image: create PDF page at chosen size, embed image with selected layout mode
4. Save PDF

Page sizes in points (1 point = 1/72 inch):
- A4: 595 × 842 (portrait) / 842 × 595 (landscape)
- Letter: 612 × 792 (portrait) / 792 × 612 (landscape)
- Legal: 612 × 1008
- A5: 420 × 595
- Custom: any dimensions in pixels or points

Layout modes:
- Fit: image scaled to fit within page with margins
- Fill: image fills whole page, cropping any excess beyond page bounds
- Actual size: image at native size, can exceed page or appear tiny
- Stretch: image stretched to fill exactly (usually not recommended)

Margins: configurable white space around each image on the page.

Orientation: auto (match image aspect ratio), portrait, or landscape.

Ordering: drag-and-drop interface for rearranging images before PDF generation. Alphabetical sort by filename as default.

Image format handling:
- JPEG: embedded directly (PDF supports JPEG natively, efficient)
- PNG: embedded with lossless compression
- WebP, GIF, BMP: converted to JPEG or PNG internally for embedding

File size: approximately the sum of input image sizes plus small PDF overhead. Very large photos produce very large PDFs; consider resizing images first if size matters.

Batch processing: all images processed in one operation, then assembled into single PDF output.

Performance: combining 10-50 images takes a few seconds; 100+ images takes longer. Memory scales with total image data — very high-resolution photo albums may strain browser memory.

Common problems and solutions

Large output size

Many high-resolution photos make large PDFs. A 20-photo album with 8 MP photos can be 100+ MB. Pre-resize images for smaller PDF.

Ordering confusion

Some tools sort alphabetically; others by upload order. Use the drag-to-reorder feature to verify sequence matches your intent.

Aspect mismatch

Mixed portrait and landscape images produce awkward whitespace with fit mode. Use auto orientation to match page to image aspect.

Memory issues

100+ high-res images can exhaust browser memory during combination. Split into smaller batches (30-50 images) and merge resulting PDFs if needed.

Quality degradation

Some tools re-compress images during PDF embedding. This tool embeds JPEGs as-is (no loss) and PNGs with PDF-compatible lossless compression.

Transparency lost

PDF doesn’t handle transparency perfectly in all viewers. If PNG transparency matters, test output in target viewer; otherwise flatten to white background.

Filename order

Drag-and-drop lets you customize order regardless of filename. If order matters, verify before generating.

Image to PDF — comparisons and alternatives

Compared to desktop PDF tools (Acrobat, Preview), this tool is free and browser-based. Desktop tools offer more features; this tool handles the common case.

Compared to print-to-PDF from image viewers, this tool offers drag-and-drop reordering and layout control. Print-to-PDF works but is less flexible.

Compared to online conversion services, this tool doesn\u2019t upload images. Many services upload to servers; this tool runs entirely in your browser.

Frequently asked questions about the Image to PDF

How do I combine images into a PDF?

Upload multiple images, reorder via drag-and-drop if needed, configure page size and layout, then download the combined PDF. Each image becomes a separate page.

What image formats can I combine?

JPG, PNG, WebP, GIF, BMP. Mixed formats work — all combined into one PDF regardless of source format.

Can I reorder before generating?

Yes. Drag thumbnails to any position. The sequence in the interface matches the sequence in the PDF.

What page size should I use?

A4 for international documents. Letter for US documents. For photos, match the aspect ratio to your images to avoid white space. Custom sizes work for specific purposes.

How many images can I combine?

Up to several hundred depending on image size and browser memory. 20-50 images work smoothly; 100+ high-resolution images may be slow.

Will image quality be preserved?

JPEG images embed without re-compression (quality preserved). PNG images embed with lossless compression. No quality loss from the PDF combination itself.

Is my data private?

Yes. All processing runs in your browser. Images and generated PDF stay local — safe for personal photos, private documents, or confidential scans.

What’s the difference from Image to PDF?

Both do similar things. This tool is optimized for batch workflows with emphasis on reordering and multi-image handling. Use whichever feels more intuitive for your use case.
