About the JPG to PDF
Most free JPG to PDF sites do two quiet things that should bother you more than they do. They upload your file to a company's server to run the conversion, and plenty of them recompress your images along the way, so the scan you get back looks a little softer than the one you handed over. This tool does neither of those things, and instead it combines your JPG and PNG images into a single PDF right in your browser. The files never leave your computer, and it drops your original image data into the PDF exactly as it is, so nothing changes on the way through.
The whole flow is three steps and takes a few seconds. Drop in your images, put them in the order you want with the arrows, and download the finished PDF. Each image becomes its own page, so five photos give you a five-page file, in the sequence you set, that looks the same on a phone as it does coming off a printer.
How to use
- Add your images. Drag your JPG and PNG files onto the drop zone, or click it to browse and grab several at once. Every new file lands at the bottom of the list, and you can keep adding as many as you want.
- Get the order right. Each image shows up in a numbered list with a thumbnail and its name. Use the up and down arrows to move one, or the ✕ to remove a file you added by mistake. The list is the PDF, top to bottom.
- Pick your page size. By default each page matches its image exactly, edge to edge, no margins. Tick Fit each image to an A4 page if you'd rather center every image on a standard A4 sheet instead.
- Create the PDF. Click Create PDF and it downloads right away as one file. Clear wipes the list so you can start over.
There's no progress bar to wait on, because there's no upload. The work happens on your machine, so even a big batch is quick.
Your images go in untouched
A lot of the popular online converters resize or re-encode your images as part of "optimizing" the PDF. For a holiday photo that might be fine. For a scanned contract, a receipt, or a page of small handwriting, honestly, it can drag readable down to borderline. This tool embeds your original file data straight into the PDF. It doesn't resize the pixels or re-encode anything, and it never touches the quality. A crisp scan stays crisp, and a grainy phone photo stays grainy, but the conversion itself makes neither one worse.
The practical move is to feed it the best originals you have. Scan or photograph at a decent resolution, add those files, and the PDF carries that quality all the way through. If the finished file ends up bigger than some upload form allows, shrink the images first or run the PDF through a compressor afterward, that's the right order to do it in. Don't count on the conversion to make anything smaller, because it deliberately doesn't. The A4 option only changes where the image sits on the page, it doesn't compress a single pixel, so it won't move the file size either.
JPG and PNG behave a little differently once they're inside the document, and you can mix both freely. JPG stays smaller and looks great for photos and natural detail. PNG keeps sharp edges, text, and flat color clean, which makes it the stronger pick for screenshots, diagrams, and scanned type. If you're combining photos, JPGs give you a lighter PDF. Screenshots and scanned text hold up better as PNGs.
It runs on your computer, not a server
The browser part matters for more than speed. When you combine a scanned ID, a stack of receipts, or medical paperwork on one of the big free sites, those images get sent off to a stranger's server, sat in a queue, and handled by machines you will never see. Maybe they delete them on schedule, maybe they don't. With this tool the question never comes up, because nothing is sent anywhere at all. Your images are read locally, assembled on your device, and the moment you close the tab they're gone.
That makes it a real fit for the paperwork people actually convert. Front and back of a license, a passport page, and the supporting documents for an application need to travel together and as a PDF, and none of it should tour the internet first. Students photographing worksheets can hand in one file the school portal will actually accept. Anyone putting together an expense report can snap receipts through the month and merge the pile at the end, instead of emailing forty tiny JPGs to accounting.
Order and page size
Two settings decide how the finished PDF looks, and order is the one to sort out before you click Create. If you're loading a numbered batch, naming the files in sequence first, like 01.jpg, 02.jpg, 03.jpg, imports them in the right order on their own. Anything out of place after that, nudge it with the arrows until the numbered list reads the way you want. The number beside each thumbnail is the page it becomes in the PDF, so a file sitting at 3 in the list comes out as page 3.
Page size is the other choice. The default sizes each page to its image, so the picture fills it with no white border, which is what you want for photos and design work where the image should look like the original. Fit to A4 instead scales each image onto one consistent, print-friendly sheet, which is the better call when the PDF is headed for a printer or getting submitted next to other documents that are all the same size. Each image keeps its own shape either way, so a wide screenshot stays wide and a tall scan stays tall. One tip if you use A4 with a mix of portrait and landscape images, sort them by shape first so the printout isn't flipping orientation every other page.
Frequently asked questions
What happens to files it can't use, like HEIC or WebP?
Only JPG and PNG can go into the PDF. If you drop in something else, an iPhone HEIC photo, a WebP, a GIF, those files get skipped and you'll see a short note saying so, while the supported ones still go through fine. Convert the odd ones to JPG or PNG first if you need them included.
Can I add more images after I've already made a PDF?
Yes. The list stays put until you hit Clear, so you can create a PDF, add a few more images, reorder, and create an updated one, because downloading does not lock anything. When you want a clean slate, Clear empties the list and resets everything back to the start.
Does reordering the pages change anything about the images?
No. Moving pages up and down only changes their sequence, not the pictures themselves. Quality is set entirely by the source files you add, and the arrows never alter those. So you can shuffle the order as many times as you like with zero effect on how anything looks.
Why do my images look centered with white space around them?
That's the Fit to A4 option at work. It puts each image on a full A4 sheet and centers it, so an image that isn't A4-shaped ends up with blank margins on the sides or top and bottom. Turn the option off and each page shrinks to the exact size of its image, and the white space disappears.
Is there a limit on how many I can combine?
No fixed cap. A handful or several dozen both work. Because it all runs in your browser's memory, a very large batch of high-resolution images will use more of it and take a moment longer, but for everyday scans and photos it's basically instant.
Will the PDF open on other devices?
Yes. It's a standard PDF with nothing proprietary baked in, so it opens in any browser, viewer, or phone app and prints normally. Once it's downloaded it's a plain file that doesn't need this tool, an account, or an internet connection to work.
