Convert JPG to PDF without uploading
Combine your JPG or PNG images into one clean PDF — one image per page — without sending a single photo to a server. Free, no watermark, and it happens entirely in your browser.
No sign-up. No upload. Nothing to install.
How to convert images to a PDF
- Open PDFLight. Go to the home page. Nothing to install, no account.
- Drop your images. Drag your JPG or PNG files onto the page. They are converted into a PDF automatically — one image becomes one page.
- Order the pages. Rearrange, rotate or delete pages in the editor until the document reads the way you want.
- Save. Click Save. The PDF is written straight to your disk — the images never left your device.
Why turn images into a PDF locally
A batch of photos is awkward to send and easy to lose track of; one PDF is tidy, prints predictably and keeps the pages in order. That is why scans of an ID, receipts, or photographed paperwork are so often bundled into a single PDF before being emailed.
Those are also exactly the images you would rather not upload. A photographed ID or a receipt carries more than its contents: phone photos travel with EXIF metadata that can include the exact time the picture was taken and, if location services were on, the coordinates where you stood. Handing that to a converter you know nothing about gives away considerably more than the document itself.
Converting locally sidesteps the transfer entirely: the images are read into your browser, embedded into a new PDF and written back to your disk without a single byte crossing the network. It does not sanitise the images, though — embedding a JPEG keeps its original data, EXIF included — so if the photos are going to a stranger, strip their metadata before converting.
One practical note: JPEG data is embedded as-is rather than re-encoded, so the conversion adds no generation loss. A photo that was 4 MB going in is roughly 4 MB inside the PDF, which is why a batch of phone photos produces a large document. Resizing the images first is the fix.
PDFLight converts the other way too: open a PDF and use Convert → "To images" to export each page back out as a picture.
Frequently asked questions
Which image formats are supported?
JPG and PNG. Each image becomes one page, sized to the image itself.
Are my images uploaded?
No. The conversion runs in your browser with pdf-lib. Your photos never leave your device.
Can I combine several images into one PDF?
Yes. Drop them all at once and they are merged into a single document, in the order you can then rearrange.
Is there a watermark or a limit?
Neither. No watermark, no image count limit, no paid tier.
Can I reorder the pages afterwards?
Yes. Once converted, drag pages into any order, rotate or delete them, then save.
