How to convert JPG to PDF

Five steps, all running locally in your browser.

01

Drop your JPG files

One file or a batch. Nothing is uploaded, everything stays on your device.

02

Reorder pages

Drag a row to a new position, or use the up and down arrow buttons.

03

Choose page size

Fit to image sizes each page to its own photo. A4 or Letter give uniform pages, with orientation and margin.

04

Set a filename, optional

Defaults to images.pdf if left blank.

05

Create and download

True JPEGs embed exactly as-is, with no re-encoding or quality loss.

Why convert JPG to PDF?

PDF is the standard format for sharing documents that need to look the same on every device and printer. When you send a JPG file, different apps and operating systems render it at different sizes. A PDF locks the layout. The recipient sees exactly what you intended.

Job applications and CVs

HR portals almost always accept PDF but frequently reject JPG for document submissions. Convert your scanned certificates, ID cards and transcripts to PDF before uploading.

Government and official forms

Visa applications, tax submissions, and permit portals typically require PDF. Convert your scanned photos to PDF to meet the format requirement.

Sharing multiple photos as one file

Instead of sending ten separate JPG attachments, merge them into one PDF. The recipient downloads a single file and sees all images in the correct order.

Receipts and invoices

Phone photos of receipts are JPG. Converting to PDF makes them easier to file, search and share with accountants or expense management systems.

Printing from a phone

PDF prints at the correct size every time. Printing a JPG directly often produces unexpected margins or scaling. Convert first for reliable results.

University and school submissions

Most online submission portals only accept PDF. Convert scanned assignment pages, certificates and photos to a single PDF before submitting.

Why browser-based conversion is better than upload tools

Most JPG to PDF tools work by uploading your file to a server, converting it there, and sending the PDF back. That means your photo passes through a third-party server. For photos of ID cards, receipts, medical documents or anything personal, that is a real privacy concern.

This tool runs entirely in your browser. Your JPG files never leave your device at any point. The PDF is built locally using pdf-lib, a well-maintained open source library, and downloaded directly to your computer. You can disconnect from the internet after the page loads and it still works.

Common JPG to PDF mistakes

Assuming only JPG files work on this page

PNG, WebP, GIF, HEIC and AVIF are all accepted too and can be mixed with JPGs freely. Just know the no-re-encoding guarantee is specific to JPEG and PNG, other formats get transcoded to JPEG at a fixed quality of 82.

Leaving page size on Fit to image for photos of different resolutions

Fit to image sizes each page from that specific photo's own dimensions, so a batch with mixed resolutions ends up with differently sized pages throughout the document. Switch to A4 or Letter for uniform pages.

Expecting the file size to shrink automatically

This tool combines images into a document, it doesn't compress them. If the finished PDF is too large for a portal's upload limit, compress your source images first, or compress the PDF separately.

Forgetting to reorder before clicking Create PDF

Pages are generated in whatever order the list shows at the moment you click Create PDF. Drag rows or use the arrow buttons to set the final order first.

Not realizing a non-JPEG file mixed in gets re-encoded

If you drop a WebP or HEIC photo alongside your JPGs, it's automatically transcoded to JPEG at quality 82 during embedding. Your true JPEGs in the same batch are unaffected and embed with zero quality loss.

Frequently asked questions

How do I convert JPG to PDF without uploading?

Drop your JPG files into the tool above. Everything runs locally in your browser using pdf-lib. Your images are never sent to any server. The PDF is generated entirely on your device and downloads directly to your computer.

Can I convert multiple JPG files into one PDF?

Yes. Drop as many JPG files as you need. They appear as individual pages in the list. Drag rows to reorder them, or use the up and down buttons. When you click Create PDF, all images are merged into a single PDF in the order you set.

Will the PDF have a watermark?

No. The output PDF has no watermarks, no branding, and no restrictions. It is a clean, standard PDF file. This is possible because all processing runs in your browser and there is no server or service to monetise.

Is there a file size limit?

There is no imposed file size limit. The practical limit is your device's available memory. Most modern phones and laptops handle dozens of high-resolution JPGs without any issue.

What page size options are available?

You can choose Fit to image (each page is exactly the size of its own source image, with no white borders), A4 (standard international paper size), or US Letter (standard North American paper size). Portrait and landscape orientation are available for A4 and Letter, and you can set a margin. One thing to know about Fit to image: since each page is sized independently from its own photo, a batch that mixes photos of different resolutions will produce differently sized pages throughout the finished PDF. Choose A4 or Letter instead if you need every page to be the same size.

Will the JPG quality be reduced in the PDF?

For actual JPEG files, no. The tool embeds true JPEG images directly into the PDF without re-encoding them, so the visual quality in the PDF is identical to the original file. This guarantee is specific to JPEG (and PNG) sources; see the next question if you're mixing in other formats.

Does this tool only accept JPG files?

No, even though this page is built around JPG, the tool underneath also accepts PNG, WebP, GIF, HEIC and AVIF, and you can mix them freely with your JPGs. The no-re-encoding guarantee only applies to native JPEG and PNG though. Every other format, WebP, GIF, HEIC and AVIF, is automatically transcoded to JPEG at a fixed quality of 82 before it's embedded, with no slider to adjust that setting on this page. If you need control over that quality, convert to JPEG first with a dedicated converter at your chosen quality, then combine the result here.

Can I set a custom filename for the PDF?

Yes. A filename field appears once you've added at least one image, defaulting to images.pdf if you leave it blank. Type whatever name you want before clicking Create PDF, the .pdf extension is added automatically.

Can I use this on my phone?

Yes. The tool works in any modern browser on iPhone, Android, and desktop. On mobile, tap the upload area to select photos from your camera roll or files app.

Are my photos private and secure?

Completely. Your images never leave your device. All PDF creation happens locally in your browser. You can verify this by disconnecting from the internet after the page loads. The conversion still works because nothing is sent to a server.
