JPG to PDF
Convert JPG photos to PDF, combining up to 500 into one file with a page per photo. Ordinary JPEGs go in without re-encoding, and sideways photos are turned upright.

How do I convert JPG to PDF?
Select up to 500 JPEG files, each up to 64 MiB. One page is produced per image, in the order listed.
Choose whether each page takes the image's own physical size or fits a fixed sheet, and set the margin if you chose a sheet.
Select Create PDF and save the result before leaving the page.
How does JPG to PDF keep the original quality?
Convert JPG photos to PDF, combining up to 500 images, such as site photographs for a report, into one PDF with one page per photo. An ordinary JPEG is placed with its compressed data untouched, so nothing is re-encoded and no quality is lost.
An ordinary JPEG's compressed data is already in a form a PDF can hold, so it is copied across byte for byte and the PDF reader decodes it just as an image viewer would. Nothing is decoded while the PDF is made, which is why a large photograph costs no more to place than a small one. The orientation a camera recorded in the file is applied, so a portrait photograph does not arrive on its side, and mirrored orientations are handled too, which turning the page alone could not do. In a Xenmark review, a site photo can also be attached straight to the comment it belongs to.
How Xenmark makes it easy to turn JPG photos into a PDF
Your JPEG bytes, placed as they are
An ordinary baseline or progressive JPEG goes into the PDF with its compressed data untouched, so the photograph on the page is the file you selected.
Nothing leaves your machine
Nothing is uploaded. Files are read in this tab and processed in memory, with no account and no server for them to go to.
Sideways phone photos come out upright
The sideways or upside-down orientation a camera records is read and applied, including the four mirrored cases that a page rotation alone could not express.
Pages at the photograph's true size
A JPEG that records its own resolution gets a page of matching physical size. Otherwise the density you set is used, and the result says so.
Fit every photo to one sheet size
Choose A0 to A6, portrait or landscape, and a margin of up to 100 mm. Each photograph is centred and scaled to fit without changing its proportions.
Nothing to install
It runs in the browser you already have. There is no plug-in, no desktop application and no sign-up to get through first.
Limitations
What this tool does not do, stated up front.
CMYK, arithmetic-coded and 12-bit JPEGs cannot be placed untouched, so your browser decodes them and they are stored losslessly instead; lossless JPEG files are refused.
When pages take each photo’s own size, a photo that does not record its own resolution (a resolution stored only in the camera’s separate metadata is not used) is sized from the density you enter, and the result says which ones.
The JPEG goes in whole, including any camera data it carries, such as where it was taken, and an embedded colour profile is not applied. Remove location data first if the PDF will be shared.
Questions
Does converting JPG to PDF reduce quality?
Not for an ordinary JPEG: its compressed data goes into the PDF unchanged, so no quality is lost. The rare JPEGs that cannot be placed that way (CMYK, arithmetic-coded or 12-bit) are decoded by your browser and stored losslessly, and the list says which.
Why is my page a strange size?
Because each page takes the photo’s own size by default: its pixel count divided by the resolution the image format itself records — not a separate camera-metadata block — or by the density you enter (96 dpi unless you change it) when there is none, and many phone photos record 72 dpi there, which makes a very large page. Choose “Fit each image to a fixed sheet” to put every photo on A4 or another A-series sheet.
Will a photograph taken sideways come out sideways?
No. The orientation the camera recorded is read and applied, including the mirrored cases.
Why did Xenmark build a free JPG-to-PDF converter?
Xenmark AS is a Norwegian software company building browser-based drawing review tools for owners, consultants, operators and other teams that receive and review technical drawings. Those teams handle PDFs every day, and not every file should be sent to a website just to merge, split or check it — a tender document, a client’s drawing set, a revision that is not released yet. So these everyday tools are free and run entirely in your browser: no account, no upload step, and no server ever receives the file. You can check that yourself — open your browser’s network tab, convert a few photographs, and watch nothing leave. What this tool cannot do is listed under Limitations above.

Beyond the free tools
Reviewing the drawings, not just handling the files?
Xenmark is affordable PDF markup and structured drawing review in the browser. Invite reviewers, pin numbered comments on the sheet, track every one by author and status, and export a clean PDF and Excel when the review is done. Unlike these tools, a review is shared, so its drawings are uploaded to your Xenmark project.
Free forever plan. Reviewers you invite never pay.
