How to Convert Images to PDF for Free - JPG, PNG, WebP to PDF

Need to submit photos as a single document? Converting images to PDF is one of the most common tasks - whether you're sending receipts, assembling a portfolio, or submitting scanned documents. You can do it for free without installing any software.

Why Convert Images to PDF?

• Document submission - many organizations require PDF, not individual images
• Multiple files into one - combine 10 receipt photos into a single PDF
• Print consistency - PDFs print the same on every device
• File organization - one file is easier to manage than a folder of images
• Email attachments - one PDF instead of 15 separate JPGs

Supported Image Formats

SnapSum Image to PDF converts all common formats:

• JPG / JPEG - the most common photo format
• PNG - supports transparency, great for screenshots and logos
• WebP - Google's modern format, increasingly common
• BMP - uncompressed bitmap images
• GIF - first frame only (for animated GIFs, use GIF Maker)

Step-by-Step: Convert Images to PDF

1. Open Image to PDF.
2. Upload your images (drag & drop or click to browse - multiple files allowed).
3. Reorder images by dragging if needed.
4. Choose page size and orientation.
5. Click "Convert to PDF" and download.

Done in seconds. Your images never leave your device.

Page Size Options

• Fit to Image - each page matches the image dimensions exactly. Best for photos.
• A4 (210 × 297 mm) - standard document size. Best for forms and printouts.
• US Letter (8.5 × 11 in) - standard in North America.

For best results with A4/Letter, use Image Resizer to adjust your images to the right dimensions first.

Image Quality Tips

• Use high-resolution source images - the PDF will only be as sharp as the input.
• For scanned documents, 300 DPI is ideal for PDF conversion.
• Compress large photos first with Image Compressor to keep the final PDF size manageable.
