Convert JPEG to PDF
We turn JPEG into PDF right in your browser — the file never goes to a server.
What you will lose
Nothing important: the target format does everything the source does.

JPEG
Good at
- Compresses photos tightly, and the loss is hard to notice
- Opens literally everywhere, including old devices and printers
- Fast to encode and open, easy on the device
Awkward about
- Lossy: every re-save degrades the image a little more
- No transparency — it turns white or black
- Visible halos appear around text and sharp edges
Use it when
- Photos that will not be edited further
- When the file has to open for absolutely anyone
Good at
- Looks the same everywhere: fonts, margins and line breaks are fixed
- The one format any office will accept without argument
- Holds text, vectors and photographs in a single file
Awkward about
- Hard to edit: it is a format for reading, not for changing
- Weight depends on what is inside — a scanned page can weigh as much as a book
- Text inside a scan stays a picture until something recognises it
Use it when
- The document is being sent, printed or filed somewhere official
- The layout must not shift on someone else’s device
- Loose pages need to become one file
Common questions
- Does the file get uploaded to a server?
- No. JPEG → PDF runs right in your browser and the file never leaves your device. It only goes to a server if the browser cannot cope — and then we delete it within a couple of hours.
- Will transparency survive?
- Yes, PDF supports transparency, so semi-transparent edges stay as they were.
- Can I get the original quality back afterwards?
- Yes, PDF supports lossless compression, so you can go back to the original.
- How many files, and how large?
- Up to 50 files at a time, 50 MB each. No sign-up, no watermarks.
