How to convert JPG to PDF
- 1
Open your .jpg file
Drag it onto the viewer above, or click "Open a JPG File". Files up to 200 MB open directly; the parse runs in a worker so the page stays responsive.
- 2
Pick PDF in the Export menu
Click Export in the toolbar, then PDF (.pdf).
- 3
Download
The .pdf is written in the browser and saved straight to your downloads folder. No queue, no email, no watermark.
What survives the conversion
A file conversion is a translation, and formats do not carry the same things. Here is exactly what moves from JPG into PDF, and what does not.
| Geometry | Reduced | The vector PDF keeps the line work as editable paths with hidden lines removed. The snapshot PDF is a picture of the view. Neither is 3-D geometry once exported. |
|---|---|---|
| Colors and materials | Kept | PDF carries full color, which is at least what JPG stores, so the colors come across. |
| Resolution | Kept | The export dialog opens at the picture’s own pixel size, so a 1x export is the same resolution as the original. You can go higher or lower before saving. |
| Camera metadata | Dropped | EXIF is not carried across: no camera model, no exposure settings, no GPS coordinates, no capture date. Only the pixels are written. That is a privacy win if you are publishing the photo and a loss if you were relying on the metadata. |
What the PDF writer emits: Two buttons: a snapshot PDF of the current view with caption headers, and a true vector PDF. The vector one re-projects a 3-D model as editable line work with hidden lines removed, and writes a 2-D drawing straight through as native PDF vector objects with its text still selectable.
The source: JPEG Image (.jpg, .jpeg)
A JPEG photograph at full resolution.
The target: PDF (.pdf)
The format anyone can open. For submittals, RFIs, markups and email.
Opens in: Any PDF reader, Bluebeam, Acrobat, Illustrator (vector output).
Your file never leaves your computer
Both the JPG parser and the PDF writer are JavaScript and WebAssembly running in your own browser tab. There is no upload step, no server-side conversion queue, and no copy of your file anywhere but your machine. That matters for drawings under NDA, for client work, and for anything you would not email to a stranger.
Frequently asked questions
▶Is this JPG to PDF converter free?
Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.
▶Is my JPG file uploaded anywhere?
No. The file is read with the browser file API and converted in the same tab. Nothing is sent to a server unless you explicitly click Share, which is a separate, opt-in feature.
▶Will my colors and materials survive the PDF export?
PDF carries full color, which is at least what JPG stores, so the colors come across.
▶How large a JPG file can I convert?
Up to 200 MB, and the ceiling adapts to how much memory your device reports. The conversion runs on your own hardware, so a desktop with plenty of RAM will handle more than a phone.
▶Can I convert PDF back to JPG?
Yes, the other direction works too. Bear in mind that anything the first conversion dropped is not restored by converting back. PDF → JPG
▶Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
