Wraps a JPEG in a PDF. The image data is embedded exactly as it is — PDF stores JPEG natively, so there is no decode and no re-encode, and the picture in the PDF is bit-for-bit the picture you started with.
No quality is lost, and that is not true of every converter
The wrong implementation — and it is common — decodes the JPEG to pixels and re-encodes it, adding a second generation of lossy compression for no reason at all. If a converter offers you a "quality" slider for JPG to PDF, that is what it is doing.
Nothing here is re-encoded. The file size of the PDF is the size of your JPEG plus about a kilobyte of structure.
Two ways to lay out the page
Standard page, scaled to fit puts the image on A4 or Letter with a margin, scaled down to fit and centred. The whole image is on the page — nothing is cropped — and the orientation matches the image by default. This is what you want if the PDF will be printed or submitted to a form.
Page exactly the size of the image makes the page dimensions match the pixels, with no margin. This is what you want for a scan, a screenshot or a photo book, where a paper-sized page with white borders would be wrong.
Multiple images
Why people need this
Nothing here is uploaded, which is the whole argument for this page over the incumbents.

Questions
- Does converting lose any quality?
- None. PDF stores JPEG natively, so the image data is copied in without being decoded or re-encoded.
- Can I put several photos into one PDF?
- Each image becomes its own PDF, then Merge PDF joins them into one in the order you choose. Both steps happen in this tab.
- Is there a watermark or a daily limit?
- Neither. There is nothing to meter, because the conversion costs us nothing.
- My image is sideways in the PDF.
- The JPEG carries an EXIF orientation flag that PDF has no equivalent for. Run it through the JPG to PNG tool first, which bakes the rotation into the pixels, then convert that.
- Is my file uploaded?
- No. The PDF is built in this tab and handed to you as a download. That matters here more than most places: the documents people convert to PDF are contracts, CVs, medical letters and manuscripts.
- Can I convert several files at once?
- Yes. Drop as many as you like, or a whole folder. Each becomes its own PDF keeping its original name.
