How to convert JPG to PDF
Add one or more JPG, JPEG, or PNG images. Review the page order, rotate any sideways image, and remove anything you do not want in the PDF.
Choose Same as image, A4, or US Letter, set the orientation and margins, then select Create PDF. The generated file is reopened and checked in your browser before the download button appears.
Combine multiple JPG images into one PDF
Each selected image becomes one PDF page, and the order shown in the workspace is the order written to the document. Drag page cards to reorder them or use Move earlier and Move later when drag-and-drop is inconvenient.
You can mix supported JPG, JPEG, and PNG files in the same document, rotate individual pages in 90-degree steps, add more images, or remove pages before creating the PDF.
Choose page size, orientation, and margins
Same as image makes each PDF page follow the effective dimensions of its source image. A4 and US Letter place the complete image inside a standard paper size without stretching or cropping it.
Auto orientation chooses portrait or landscape separately for each image. You can also force Portrait or Landscape for every page. Margins are None (0 pt), Small (24 pt), or Large (48 pt).
Does converting JPG to PDF reduce image quality?
Ordinary JPG images are embedded from their existing compressed bytes when the selected operation allows it, so the converter avoids an unnecessary JPG-to-canvas-to-JPG re-encode. Page placement handles scaling and normal rotation inside the PDF.
PNG input is embedded as PNG and can keep alpha transparency. Phone-photo EXIF orientation is respected; mirrored EXIF cases are normalized once to PNG so the finished page displays in the expected orientation.
The converter creates a PDF rather than compressing the source images. A PDF can therefore be larger than one JPG because it adds document structure and, for multi-page files, contains every selected image stream.
Convert images to PDF without uploading them
Image inspection, thumbnail preparation, PDF creation, and output verification run in the browser. Source images and generated PDF bytes are not uploaded to Olivez or a third-party conversion service.
The documented limits are safeguards rather than a promise that every maximum-size batch will fit every device: up to 40 images, 50 MiB per image, 250 MiB combined, and 80 million pixels per image. Available browser memory can impose a lower practical limit.
JPG to PDF page-size options
Portrait dimensions are shown below; Landscape swaps the width and height.
| Page size | Dimensions | What happens |
|---|---|---|
| Same as image | Source pixels × 0.75 pt | Page follows each image's effective dimensions |
| A4 | 595.28 × 841.89 pt | Image is fitted proportionally inside A4 |
| US Letter | 612 × 792 pt | Image is fitted proportionally inside US Letter |
JPG to PDF FAQ
Can I combine multiple JPG images into one PDF?
Yes. Add multiple supported images and they are written to one PDF in the order shown in the workspace.
Can I reorder or rotate pages before creating the PDF?
Yes. Drag page cards or use Move earlier and Move later to change the order, and rotate individual images in 90-degree steps before creating the PDF.
Can I choose A4, US Letter, orientation, and margins?
Yes. Choose Same as image, A4, or US Letter; use Auto, Portrait, or Landscape orientation; and select None, Small, or Large margins.
Does converting JPG to PDF reduce image quality?
Ordinary JPG streams are embedded directly when orientation allows it, avoiding an unnecessary JPEG re-encode. Mirrored EXIF cases are normalized to lossless PNG so they display correctly.
Can I convert PNG to PDF too?
Yes. Static PNG files are supported and PNG alpha transparency is preserved by the PDF embedding path.
Are my images uploaded to a server?
No. Image inspection, PDF generation, verification, and download preparation happen in the current browser.
What are the JPG to PDF limits?
The tool accepts up to 40 images, with a 50 MiB per-image limit, 250 MiB combined source limit, and 80-million-pixel limit per image. Device memory can impose a lower practical limit.
Why can the PDF be larger than the original JPG?
A PDF adds document structure around the image data, and a multi-page PDF contains every selected image stream. This converter focuses on document creation rather than image compression.
