JPG → PDF
JPG to PDF converter
Drop your JPGs and get a single PDF back, one photo per page, in the order you added them. The pages are assembled in this tab, so a folder of scans never leaves your machine.
Each JPG becomes one page and its bytes are copied in unchanged, so quality is untouched — but a PDF has no text layer, and each photo is placed inside the page box you choose.
How to convert JPG to PDF
Add the JPGs
Drop one or more JPG or JPEG files on the box above, paste them from the clipboard or pick them from disk. Every file becomes a page, in the order it was added.
Set the page
Pick A4, US Letter or fit-to-image and set the margin in points — 72 points make one inch. Fit gives each page the frame of its own photo; A4 and Letter give the document one frame throughout.
Download the PDF
Convert and save the single PDF. The JPEG streams go in as they are, so the pages keep exactly the detail the files had.
What a PDF does with a JPEG
A PDF is a container of pages: each page has a fixed box and a short list of instructions saying what to draw inside it. A JPEG fits that model unusually well, because it is already a compressed stream that every PDF reader decodes natively. This tool therefore copies the JPEG's bytes straight into the page and never touches a pixel — nothing is re-encoded, nothing is upscaled, and whatever the photo's own compression did to it stays exactly as it was.
The consequences run in both directions. The finished PDF is close in size to the sum of your JPEGs plus a few kilobytes of page structure, which is why an album or a scanned chapter converts in seconds. But a PDF page is a picture, not an editable document: no text layer is created, the JPEG's own header and metadata travel untouched inside the stream, and the page size you pick decides the frame rather than the pixel count — a 4000-pixel photo placed on A4 is scaled by the viewer to fit that box when it is displayed or printed.
JPG to PDF questions
Do I have to upload the JPGs?
No. The files are read from your disk, laid out as PDF pages in this tab and written straight back to your disk, so nothing is sent to a server. That also means the converter keeps working with the network off once the page has loaded.
Is the image compressed again when it becomes a PDF?
No. The JPEG stream is embedded as it stands, which is why there is no quality slider on this page — any slider would have to re-encode the photo, and that is the one thing this conversion avoids. The trade is that the result is a picture page: no text layer, no reflow, no editing inside the PDF.
Which page size and margin should I use?
A4 is 595 by 842 points and US Letter is 612 by 792, so the choice matters mainly when the PDF will be printed. A margin of 36 points is half an inch, enough to keep content clear of the paper edge; 0 points fills the sheet, which is the usual pick for pages meant to be read on a screen.
How many JPGs can go into one PDF?
The tool sets no page count, but each input file must be under 64 MB and the whole document is assembled in your browser's memory. Fifty phone photos are unproblematic; several hundred scans are where a desktop browser is the sensible place to do the work.
