How to convert JPG to PDF

  1. 1

    Drop your JPG files

    Add up to 200 photos at once. They are read by your own browser, so nothing is uploaded and nothing waits in a queue.

  2. 2

    Set page size and order

    Choose a page that fits each photo exactly, or A4 and Letter for printing. Set margins, then drag the thumbnails into the order you want.

  3. 3

    Download the PDF

    One document comes back with a page per photo. Turn off merging to get a separate PDF for every image inside a ZIP.

Why the photos keep their original quality

A JPG is already a compressed stream, and a PDF page can carry that stream untouched. This converter copies the bytes of every photo straight into the document instead of decoding and re-compressing them, which is what a screenshot-and-save workflow or an image editor would do. The practical result is that the PDF weighs roughly as much as the photos it contains, and a picture pulled back out of it is identical to the file you started with. It also means conversion is fast: ten three-megabyte photos take about two seconds, because nothing has to be decoded on the way in.

Page size, margins and orientation

Fit gives every page the exact size of its photo, so nothing is cropped and no white border appears. A4 and Letter place each photo on a fixed sheet, scaled to fill the space inside the margins and centred both ways. Orientation is picked from the photo itself unless you force portrait or landscape. Margins run from 0 to 50 millimetres and are applied on all four sides, which matters for printing: home printers cannot print to the edge of the paper and will crop a borderless page.

Your photos never leave this device

Everything happens inside the browser tab: the files are read from disk, assembled into a PDF and handed back as a download. Nothing is sent to a server, nothing is stored for us to delete later, and no account is needed. Passport scans, receipts and family pictures are safe to convert here, and once your first photos are in, the page keeps working with the connection switched off.

Frequently asked questions

Does converting JPG to PDF lose quality?

No. The photo is embedded as the same JPEG stream it already was, so it is never decoded and never compressed a second time. Extract the image from the finished PDF and you get back the file you put in, byte for byte.

Why is the PDF about as large as my photos?

Because it contains them unchanged. A PDF is a container, not a compressor, so the document weighs the sum of the photos plus a few kilobytes of structure. If you need a smaller file, compress the finished PDF or resize the photos first.

How do I change the order of the pages?

Drag the photo thumbnails into place, or use the arrows next to each name in the file list. The pages of the PDF follow that order, and the preview is rebuilt as you go. The names of the files do not matter, so photos numbered out of sequence can still be arranged the way you want.

What does the fit page size do?

It makes every page exactly as large as the photo on it, measured at 72 points per inch. No scaling, no white borders and no cropping. Choose A4 or Letter instead when the document will be printed on real paper.

Why are my phone photos no longer sideways?

Phones save the picture as the sensor read it and note the rotation in an EXIF tag. This tool reads that tag and turns the page accordingly, so images that look rotated in simpler converters come out upright here.

Can I get a separate PDF for every photo?

Yes. Turn off the merge switch and each image becomes its own one-page PDF, named after the original file. When there is more than one, they arrive together in a single ZIP archive.

Is there a limit on how many photos I can add?

Up to 200 files at a time, 100 megabytes each and 500 megabytes in total. For a larger set, convert it in batches and join the resulting documents with the merge tool, which keeps the order you give it.

Which margin should I use for printing?

Ten millimetres is a safe start for most home printers, which cannot print to the very edge of the sheet. Pair it with A4 or Letter rather than fit, so every page has the same size and the printer does not rescale them.
