How to Convert JPG to PDF
PDF (Portable Document Format) is the universal standard for sharing documents. Converting your photos or scanned images to PDF ensures they display identically on any device, without the recipient needing any specific software.
PhotoRule uses jsPDF — a client-side JavaScript library — to generate the PDF entirely in your browser. Each image is drawn onto an HTML Canvas, encoded as JPEG data, and embedded into a standard PDF document. The resulting file is immediately available to download.
Tips for best results
- Use high-resolution JPG images for crisp PDF output
- Choose Fit Image mode for photos to avoid white borders
- Use A4 for documents intended for international printing
- Use Letter for US standard documents
Frequently Asked Questions
How do I convert JPG to PDF for free with no watermark?
Upload your JPG images above, choose A4, Letter, or Fit Image page size, and click Convert. PhotoRule generates the PDF entirely in your browser using jsPDF — no watermark, no signup, no server upload.
Can I merge multiple JPG files into one PDF?
Yes. Upload multiple images — each becomes a separate page in a single PDF. You can remove individual images before converting and reorder them by adding them in the order you want.
Does converting JPG to PDF reduce image quality?
PhotoRule embeds images at 92% JPEG quality, which is visually lossless for most photos. For maximum quality, use high-resolution source images (at least 300 DPI for print-ready PDFs).
What page sizes are supported?
A4 (210×297mm — international standard), US Letter (215.9×279.4mm), and Fit Image (the PDF page matches each image's exact dimensions with no white borders).
Is there a limit on how many JPG files I can convert?
No. You can add as many images as you want. Since conversion happens in your browser, very large batches may take a few seconds but there is no server-side limit.
Does my file get uploaded to a server?
No. PhotoRule uses jsPDF, a client-side JavaScript library. Your images are processed entirely in your browser and never transmitted anywhere.
