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 to lose, and nothing to gain: {to} keeps exactly what {from} hands over, and the file grows several times over.

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?
- Nothing is lost, but nothing is gained either. PDF stores exactly what JPEG hands over, including the gaps JPEG left behind when it compressed. No tool can bring those back, and the file grows several times over. This conversion makes sense for editing, not for quality.
- How many files, and how large?
- Up to 50 files at a time, 50 MB each. No sign-up, no watermarks.
