Free JPG to PDF Converter - Browser-Based, No Upload Required
Combine JPEG and PNG images into one PDF directly in your browser. Multi-page output, page size control, margins, no upload, no account.
By Sunny Kumar · Editor
Combine JPEG and PNG images into one PDF directly in your browser. Choose fit-to-image, A4, Letter, or Legal page size, set a margin, and download a multi-page PDF. Nothing is uploaded.
TL;DR: Use this when a form, client, school, bank, or workflow wants one PDF instead of separate images. Each selected image becomes one page. This tool packages images into a PDF; it is not a deep PDF compressor.
Processed locally, never uploaded
PDF generation runs in your browser via pdf-lib. No server, no tracking, no uploads.
How to Use This Converter
- Click "Choose Files" and select JPEG or PNG images
- Pick a page size: fit, A4, Letter, or Legal
- Set the margin in points
- Click "Build PDF"
- Download the generated PDF
Files combine in the order your browser provides them from the file picker. If order matters, rename files before selecting them, for example 01-front.jpg, 02-back.jpg, 03-receipt.jpg.
What This Converter Actually Does
This tool uses pdf-lib in your browser to create a new PDF and embed each selected image as a page.
| Need | What happens here |
|---|---|
| One PDF from many images | Each image becomes one page |
| Standard paper output | A4, Letter, and Legal are available |
| Native image size | Fit-to-image keeps the page close to the image dimensions |
| Privacy | Files stay in your browser; no server receives them |
| Compression | Images are embedded; they are not aggressively recompressed |
JPEG inputs are embedded as JPEG. PNG inputs are embedded as PNG. That keeps the workflow predictable, but it also means the output PDF size mostly depends on the size of the source images.
When JPG to PDF Makes Sense
Use this converter when one PDF is easier to submit, share, print, or archive than many image files.
Common use cases:
- Receipts for expense reports
- ID scans or passport pages
- Homework, notes, and worksheets
- Screenshots for support tickets
- Proof-of-work or portfolio handoff
- Signed pages photographed separately
- Simple document archives
For website delivery, PDF is usually the wrong format. Use optimized images and an image CDN instead.
Which Page Size Should You Pick?
| Page size | Use for |
|---|---|
| Fit to image | Screenshots, receipts, scans, and images that should keep their natural dimensions |
| A4 | European business, school, and government workflows |
| US Letter | US business, school, and everyday printing |
| US Legal | Legal filings and long-form document workflows |
Margins are in PDF points. There are 72 points in one inch. A margin around 24 points is a practical default; 0 points places the image at the page edge.
With fixed page sizes, oversized images are scaled down to fit inside the page and margin. The tool does not crop images.
Will the PDF Be Smaller Than the Images?
Usually no. This tool packages images into a PDF. It does not heavily recompress them.
If you want a smaller PDF, compress the images first with the bulk image compressor, then build the PDF from those smaller images. If you already have a finished PDF, use the PDF compressor and analyzer to see whether a lossless rewrite can help.
Why Browser-Based Conversion Matters
PDFs often contain sensitive material: IDs, receipts, medical paperwork, contracts, school documents, or client work. A browser-based converter avoids uploading those files to a third-party server.
This tool gives you:
- Privacy: files stay on your device
- Speed: no upload queue
- No accounts: no signup or watermark
- Control: page size and margins are visible before building
Frequently Asked Questions
How do I convert multiple JPGs into one PDF?
Select multiple JPEG files in the tool above, choose page size and margin, then click Build PDF. Each image becomes one page.
Does this upload my images?
No. PDF creation runs locally in your browser using pdf-lib.
Can I use PNG files too?
Yes. The tool accepts JPEG and PNG input.
Can I rearrange pages after selecting files?
Not inside this tool. Files are added in the order supplied by the browser. Rename files with numeric prefixes before selecting them if order matters.
Will this compress my images?
No meaningful compression is applied. The tool embeds images into a PDF. Compress images first if output size matters.
Is there a file-size limit?
There is no server-side limit because the tool runs locally. Very large images and big batches can still hit browser memory or device performance limits.
Summing Up!
This JPG to PDF converter is best for packaging images into one private, shareable PDF. It runs locally, supports JPEG and PNG, and gives you page size and margin control.
For smaller PDFs, compress source images first. For web performance, skip PDF and serve optimized images through an image CDN.
