How to Convert JPG to PDF

You have JPG photos that need to become a PDF — for a job application, an insurance claim, a homework submission, or a property inspection report. The process should be dead simple, and with KuroPDF, it is.

Unlike cloud converters that impose file limits, add watermarks, or require accounts, KuroPDF runs entirely in your browser. Your photos stay on your device. There is no upload queue, no processing delay, and no daily cap. Convert one image or a hundred — same tool, same speed.

Frequently asked questions

Can I combine multiple JPGs into one PDF?

Yes — that is the primary use case. Add as many images as you need, arrange them in order, and export as a single multi-page PDF.

Is there any quality loss?

No. Your original JPEG data is embedded directly into the PDF without re-encoding. The images are bit-for-bit identical.

What page sizes are available?

Fit to image (variable page sizes), A4, US Letter, Legal, or custom dimensions with adjustable margins.

Does this work on iPhone and Android?

Yes. The tool works in Safari, Chrome, and Firefox on mobile devices. Same functionality as desktop.

Are my images uploaded anywhere?

Everything runs locally in your browser using WebAssembly. Because no data is uploaded to a cloud server, your files remain strictly private, and the entire process generates zero server carbon emissions, making it highly eco-friendly.

Can I convert other formats (PNG, HEIC, WebP) too?

Yes — the Image to PDF tool accepts JPG, PNG, WebP, HEIC, GIF, BMP, TIFF, and SVG. All formats work in the same interface.

The real difference

Why KuroPDF exists

Every other PDF tool uploads your files to their servers. We think that is broken. Here is what we do differently - and what the alternatives actually cost you.

Nothing leaves your device

Files are processed in your browser using WebAssembly. Open DevTools → Network tab and verify: zero upload requests. Ever.

What competitors do instead:

Smallpdf, iLovePDF, and Adobe Acrobat all upload your files to their servers - your contracts, bank statements, and medical records pass through third-party infrastructure.

No file size limits, no daily caps

Process a 500-page PDF or batch-convert 200 photos. No cap, no throttle, no upgrade wall. Your device is the only limit.

What competitors do instead:

Smallpdf limits free users to 2 tasks per day. iLovePDF caps file sizes at 100MB. Adobe requires a $19.99/mo subscription for basic features.

Works completely offline

Install KuroPDF as a progressive web app. After the first visit, every tool works with zero internet - on a plane, in a bunker, wherever.

What competitors do instead:

Every cloud-based PDF tool stops working the moment your Wi-Fi drops. No connection = no work.

Real encryption, not security theatre

Password protection uses AES-256 encryption via a WebAssembly build of qpdf. The password never leaves your machine - there is no server to intercept it.

What competitors do instead:

When you 'protect' a PDF on Smallpdf or iLovePDF, your unencrypted file and password travel to their server, get processed, then get sent back. That is not security.

Free forever, no account needed

No login wall, no email harvesting, no 'continue with Google' popup. Open the site, use the tool, close the tab. Done.

What competitors do instead:

Adobe charges $239/yr. Smallpdf charges $108/yr. iLovePDF charges $84/yr. All require account creation to use basic tools.

Professional-grade codecs

MozJPEG for JPEG, OxiPNG for PNG, AVIF and WebP encoders - the same codecs used by Google and Mozilla. Not generic re-encoding.

What competitors do instead:

Most cloud tools use basic server-side encoders with less optimization control. You get worse compression at lower quality.
