JPG to PDF Converter
Convert one or more JPG/PNG images into a single PDF — in your browser.
Why convert images to PDF?
PDF is the universal document format for sharing and submitting files. Many portals, employers, and institutions accept only PDFs rather than raw image files. Converting photos to PDF is the most common way to bundle scanned documents — a scanned ID card, a utility bill, or a handwritten form — into a format that is expected across professional and government workflows.
You might need this tool when submitting KYC documents to a bank, attaching scanned certificates to a university application, creating a multi-page portfolio from photos, or sending a set of invoices as a single printable file.
How the conversion works
ToolJiffy uses the pdf-lib library to embed each image directly into a new PDF page. JPEG images are embedded using native JPEG encoding (lossless pass-through) and PNG images are embedded as-is. This means the PDF output quality exactly matches the input image quality. No additional compression is applied during embedding unless you explicitly compress before converting.
Best practices
For documents that need to meet size limits (email attachments under 10 MB, for example), compress images first with our Image Compressor before adding them here. To add HEIC photos from your iPhone, convert them to JPG first using theHEIC to JPG tool, then come back here to build your PDF.
Frequently Asked Questions
Can I add multiple images to one PDF?
Yes. Add as many JPG or PNG images as you want. Each image becomes one page in the output PDF. Use the arrows to reorder pages.Do my images get uploaded to a server?
No. The conversion uses pdf-lib entirely in your browser. Your images are never transmitted anywhere.What is the page size of the output PDF?
Each page is sized exactly to match the pixel dimensions of the corresponding image. There are no added margins or borders.Does the tool support PNG as well as JPG?
Yes. Both JPEG and PNG images are supported. For HEIC/HEIF images from iPhones, first convert them using our HEIC to JPG tool.Can I compress the PDF after creating it?
The generated PDF size depends on the source image sizes. For smaller output, compress your images first using our Image Compressor before converting to PDF.Is there a file size limit for input images?
There is no enforced limit, but very large images (30+ MB each) may be slow to embed depending on your device. For exam or portal submissions, compress images first.
