Image to PDF Converter

How to use this tool

1. Add images. Drag and drop images onto the drop zone, or click Browse files to select them. JPEG, PNG, WebP, and GIF are supported.
2. Reorder (optional). Drag the image thumbnails or use the Move earlier and Move later buttons. Use Rotate left or Rotate right to correct an image before conversion. The numbered badge shows the page position.
3. Set options. Choose page size (A4, Letter, or Auto), orientation (including Auto to match each image), margin, and output filename.
4. Generate and download. Click Generate PDF. When ready, click Download PDF to save the file to your device.

PDF image compression

This tool embeds your images at their current resolution and format. For smaller PDF output:

• Compress images with the Image Compressor before adding them here
• Convert PNGs to JPEG or WebP (smaller file sizes for photographs) using the Image Format Converter
• Resize images to your target page DPI before combining - a 6000×4000 photo embedded in an A4 page adds significant file size with no visible quality benefit at print scale

Accessible PDF note

A PDF containing only embedded images is not text-searchable and cannot be read by screen readers, making it inaccessible to visually impaired users and search engines. If your PDF needs to be:

• Searchable: run the PDF through OCR (Optical Character Recognition) software such as Adobe Acrobat, Tesseract, or an online OCR service after creation
• Screen-reader accessible: use a proper document authoring tool (Word, InDesign, LaTeX) rather than an image-based PDF for text-heavy documents

How to combine images into a PDF

Drop your images onto the drop zone or click Browse files to select them. Drag the thumbnails to reorder, choose your page settings, then click Generate PDF. Everything runs in your browser using pdf-lib: your images are never uploaded to any server.

Supported image formats

JPEG and PNG are embedded natively into the PDF, preserving full quality. WebP and GIF are converted to PNG first using an HTML canvas before embedding. Animated GIFs contribute only their first frame. HEIC and HEIF photos are not supported yet; convert them to JPEG with the Image Format Converter before adding them.

Choosing a page size

A4 (210 × 297 mm) is the international standard used throughout Europe and most of the world. Letter (8.5 × 11 in) is the North American standard. Auto resizes each page to fit its image exactly at 96 DPI: useful when you want the PDF dimensions to match the original image dimensions.

Rotate images and match page orientation

Rotate a thumbnail clockwise or counterclockwise when a phone photo or scanned receipt appears sideways. Rotation is applied while drawing the image into the PDF, so JPEG files keep their original embedded image data. With A4 or Letter selected, choose Auto orientation to give each page a portrait or landscape layout that matches that image after rotation. Choose Portrait or Landscape when you need every page to use the same direction.

Setting a margin

A margin adds white space around the image on the page. Images are centered within the available area while preserving their aspect ratio. Select None to fill the page edge-to-edge.

Reordering pages

Drag any thumbnail card or use its Move earlier and Move later buttons to change the page order. The numbered badge in the top-left corner of each card shows the current page number in the output PDF.
