JPG to PDF Converter

Turn JPG files into PDF in a couple of clicks. JPG is the universal lossy photo format; PDF is a fixed-layout document format that looks identical everywhere. The conversion is lossless — every pixel, sample or byte in the source is preserved.

How to use it

  1. 1

    Add your JPG files

    Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.

  2. 2

    Adjust the settings if you want to

    The defaults suit most people. Open Advanced to control page size and margins.

  3. 3

    Convert and download

    Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your JPG file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your JPG file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

PDF is the format people use for exactly the documents they would not hand to a stranger. It matters more than it sounds, because of what PDFs usually are:

Passport and visa scans

the single most useful document for identity theft

Medical letters and results

a diagnosis is not something to leave on a server

Payslips

salary, employer, and usually your home address

Bank statements

account numbers, balances, every payee you have

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

JPG and PDF explained

JPEG is a lossy image format designed for photographs. It works by discarding detail the human eye is least likely to notice, particularly in colour and in smooth gradients, which is why it compresses photos far better than it compresses text or line art.

PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.

Where JPG files come from
Digital cameras, phone screenshots on Android, and essentially every photo on the pre-2015 web.
Where PDF is used
Contracts, invoices, reports, forms, academic papers and scanned documents.

JPG vs PDF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

Why convert JPG to PDF?

Converting JPG images to PDF packages them into a single paginated document. That matters when you are submitting scans, assembling receipts, or sending several images to someone who should receive one file rather than an inbox full of attachments.

JPG limitations that prompt the switch
No transparency — there is no alpha channel at all. Visible artefacts around sharp edges and text. Every re-save degrades the image further (generation loss).
What you give up
Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run.

Does converting JPG to PDF reduce quality?

Going from JPG to PDF moves already-compressed data into a format that stores it exactly. Nothing is lost from this point on, but nothing is recovered either — the detail JPG discarded when the file was first created is gone permanently. Expect a noticeably larger file for identical visual quality.

Saving a JPEG at 100% quality is still lossy — it is a large file that has been through the same discarding process, not a lossless copy.

Measured, not estimated

What converting JPG to PDF actually costs

It depends entirely on the content: across the samples the PDF ranged from about the same size to 8% larger, with a middle case 4% larger.

Produced by this site's own converter. The same code that runs in your browser, at the same default settings, so these are the bytes you would download.

Samples are generated from a fixed seed rather than taken from real photographs or documents, so the corpus is reproducible and carries no licensing question — and so the numbers predict the shape of your result rather than its exact size.

Good to know

JPG to PDF Converter — questions

How do I convert JPG to PDF?

Drop your JPG file onto the area above, then press Convert. The PDF file saves straight to your device. You do not need an account, and there is no watermark.

Is it safe to convert JPG files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your JPG file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential JPG files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

What should I know before converting JPG to PDF?

Every image becomes a page. Turn off “Combine all files” to get one PDF per image instead.

Does converting to PDF reduce quality?

No. PDF is a lossless format, so the conversion preserves exactly what is in your JPG file. Note that it cannot recover detail that was already discarded when the JPG was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android. Pick the file through your phone's file picker — Files on iOS, or Downloads on Android — including files stored in iCloud or Google Drive.
