What this is for
The usual reason: someone has asked for “one PDF” and you have a folder of photographs. A phone photo of every page of a contract, a passport and a utility bill for an application form, receipts for an expense claim, a set of product shots that has to arrive as one document.
The pictures are almost always exactly the thing you would rather not upload. That is the point of doing it here: your browser builds the PDF, so the photographs are never transmitted, and there is no server-side copy to worry about afterwards.
Order, page size and orientation
Three things decide whether the result looks like a document or like a pile of pictures, and all three are set below before you convert:
- Order. Files are added in the order you dropped them and can be dragged into place. Phone cameras name files by timestamp, which is often — but not always — the order you want.
- Page size. A4 or Letter to match what will be printed, or a page fitted to the image when the PDF is only ever going to be read on screen.
- Orientation. Portrait or landscape, applied to the pages. A photo taken sideways is a rotated photo, not a landscape page.
Why not just “print to PDF”?
You can, and for a single image it is fine. It falls apart on the ordinary case: printing a multi-selection from a file manager gives you the order the file manager felt like using, wide margins you did not ask for, and a page break wherever the print driver decided. Building the PDF directly puts the order and the page geometry back in your hands.
On quality and file size
JPEGs are placed into the PDF as JPEG data. A twelve-megapixel photo is a large photo whether it sits in a folder or in a PDF, so twenty of them make a large PDF. If it has to be emailed, compress the images first and then build the document — compressing the photographs is far more effective than anything that can be done to the PDF afterwards.
How to convert JPG to PDF
Step 1: Add your JPG files
Drag them onto the box above, or click to select several at once.
Step 2: Put them in order
Drag the thumbnails until the sequence is right. This is the page order of the finished PDF.
Step 3: Choose page size and orientation
A4 or Letter for something that will be printed; fit-to-image for a document that will only be read on screen.
Step 4: Build and download
Press the button. The PDF is assembled in your browser and downloads straight away.
Frequently Asked Questions
How many JPGs can I put into one PDF?
There is no limit set by us. The practical ceiling is your browser’s memory — dozens of phone photos are routine; several hundred large ones on an older phone may not be.
Is there a watermark or a page limit?
No watermark, no page limit, no account, no daily counter. The output is the document itself.
Are my photos uploaded to a server?
No. The PDF is assembled by this page in your browser. The project has no API route that accepts a file, so there is nowhere for a photo to be sent.
Can I mix JPG and PNG in the same PDF?
Yes — add both and order them together. If your files are mostly PNG, the PNG to PDF page explains the one difference that matters, which is transparency.
Can I get the images back out of the PDF later?
Yes, with PDF to PNG, though what comes back is a render of the page rather than the original file byte for byte. Keep the originals if they matter.
