Convert JPG to PDF

You have a stack of JPG photos — scanned receipts, signed forms, whiteboard snapshots from a meeting — and someone needs them as "one PDF." Sound familiar?

Most online converters make you upload every image to their server, wait for processing, then pray they do not slap a watermark on the output. KuroPDF skips all of that. Drop your JPGs in, drag them into order, and export a clean PDF. The entire conversion happens in your browser using WebAssembly, so a 200-page photo album converts just as fast as a single image — and nothing ever leaves your device.

There is no file-count limit, no resolution cap, and no daily quota. Whether you are digitizing a shoebox of family photos or assembling a property inspection report, the tool handles it without complaint.

The output is a standards-compliant PDF where each image becomes a full page. You choose between fitting images to the page or using the image dimensions as the page size. Either way, zero quality is lost — the original JPEG data is embedded directly.

How to convert jpg to pdf

  1. 1
    Drop your JPGs

    Drag and drop your JPEG images into the browser dropzone — or click to browse. You can add dozens or even hundreds at once. Nothing is uploaded to any server.

  2. 2
    Arrange the page order

    Click and drag the thumbnails to put pages in the exact sequence you need. Sort alphabetically with one click if your files are already named in order.

  3. 3
    Choose page settings

    Pick "fit to image" for photo books, or select A4/Letter with margins for printable documents. Auto-orient ensures landscape photos get landscape pages.

  4. 4
    Export and download

    Hit "Save PDF." The WebAssembly engine compiles your images into a single PDF instantly. For large batches, a progress bar shows exactly where things stand.

Frequently asked questions

Is there a file size or count limit?

No. Conversion runs locally on your device, so the only limit is your available memory. Users regularly convert 100+ images in one session.

Do my images get 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 reorder the pages after adding images?

Yes — drag thumbnails into any order, or use the A-Z sort button for alphabetical/numeric sorting. The final PDF follows your arrangement exactly.

Will converting to PDF reduce my image quality?

No. KuroPDF embeds the original JPEG data directly into the PDF without re-encoding. Your images remain bit-for-bit identical.

What page sizes are available?

You can match the page size to each image (variable pages), or set a fixed size like A4, US Letter, or Legal with custom margins. Landscape images automatically get landscape pages when auto-orient is enabled.

Can I convert iPhone photos (HEIC) to PDF too?

Yes — the Image to PDF tool accepts HEIC, PNG, WebP, GIF, BMP, TIFF, and SVG in addition to JPG. 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.
