Converting photos to PDF is a daily task for many people — scanning documents, creating portfolios, archiving receipts, or combining multiple screenshots for review. This guide shows you how to do it instantly, for free, without uploading to a server.

How to convert images to PDF for free

Use Picovert's Image to PDF converter. It uses jsPDF running entirely in your browser — no server upload, no account, no file size limits beyond your device memory.

Open the Image to PDF converter.
Drop your images (JPG, PNG, WebP, AVIF supported). You can add up to 20 at once.
Drag to reorder pages if needed.
Click "Convert to PDF" and download the result.

Page orientation and size

Each image is placed on a separate page. The tool automatically detects portrait vs landscape orientation and adjusts the page accordingly. All pages use A4 dimensions by default, with the image scaled to fit while maintaining aspect ratio.

Tips for better PDF quality

Start with high-resolution images — JPEG quality 80+ or PNG lossless. Low-quality source images will look blurry in print.
Compress first if file size matters — Use Picovert's compressor before converting if the PDF will be emailed or shared.
Straighten images first — Use Picovert's rotate tool if scanned documents are tilted.

Alternative methods

Windows — Open images in Paint, print to "Microsoft Print to PDF" printer.
macOS — Open images in Preview, select all, File → Print → Save as PDF.
iPhone — Open photos in Files app → Share → Print → pinch-zoom the preview → Share → Save to Files as PDF.

All these native methods require multiple steps. Picovert's browser tool does it in one, and also handles multiple images simultaneously.
