JPG to PDF
Convert JPG to PDF — Free Online Tool
Combine one or more JPG photos into a single PDF, with the bytes embedded untouched.
About JPG to PDF
JPG is the format cameras, phones, and scanners produce, and PDF is the format forms, portals, and offices expect — this tool bridges the two without touching your pixels. Each JPG is embedded into the PDF byte-for-byte using pdf-lib's native JPEG path: the file is never decoded or re-encoded, so there is zero quality loss and the PDF weighs roughly what the photos weigh. Drop in one photo or a whole set, drag the cards to set page order, and choose a page size — A4 or US Letter, where each image is centered inside a 40-point margin and scaled down (never up) to fit, or fit-to-image, where every page matches its photo's exact dimensions. Everything runs in your browser; no file leaves your device. Common uses include submitting receipts as one document, packaging scanned pages for a portal that only accepts PDF, and turning photo sets into a single shareable attachment. A misnamed file is no problem either — the tool routes on the actual bytes, not the extension.
Questions
Does converting JPG to PDF lose quality?
No. Your JPG bytes are embedded into the PDF exactly as they are — pdf-lib's JPEG path never decodes or re-encodes them, so the pixels in the PDF are the pixels in your file.
Can I combine multiple JPGs into one PDF?
Yes. Each JPG becomes one page. Drag the thumbnail cards to set the page order, and use the Add image slot to append more photos before creating the PDF.
What happens if my file is really a PNG renamed to .jpg?
It still works. The tool routes on the file's actual bytes, not its name, so a misnamed PNG is embedded through the PNG path instead of corrupting the document.
How big will the PDF be?
Roughly the size of your JPG files combined, plus a small structural overhead — nothing is re-encoded, so nothing grows or shrinks. A 5 MB photo contributes about 5 MB to the PDF.
Is my file uploaded to a server?
No. Transmute processes everything locally in your browser using JavaScript and WebAssembly. Your files never leave your device — there is no server, no upload, no cloud processing.
