Frequently asked questions
Does converting JPG to PDF reduce image quality?
No. The JPG data is embedded into the PDF without recompression — what goes in is exactly what comes out.
Can I combine multiple JPGs into one PDF?
Yes — that's the main use. Drop them all, order them, and you get a single PDF with one photo per page.
What's the difference from Image to PDF?
Same engine, different front door. JPG to PDF is tuned for JPEG files; Image to PDF also accepts PNG, WebP, GIF, and BMP.
Can I set the page to A4 for printing?
Yes. Choose A4 (portrait or landscape) and your photos are laid out for a standard printer, with adjustable margins.
Is there a watermark on the output?
No. The PDF you download contains your photos and nothing else — free, no signup, no branding.
Do my photos get uploaded?
Never. The conversion runs locally in your browser.
