JPG to PDF
Turn a set of images into a single PDF. JPG, PNG, WebP, and iPhone HEIC all work. Reorder the pages, pick a page size, and download — all inside this browser tab, with no upload. Part of the Switch Labs PDF toolkit.

JPG, PNG, WebP, and HEIC from an iPhone. Everything runs in this tab; nothing is uploaded.
The photographed-document problem
Most people converting images to PDF are not making a photo album. They photographed a document because they do not own a scanner, and something on the other end will only accept a PDF: a landlord, a bank, a school, an insurer, a government portal.
Which means the images being converted are, very often, an ID, a bank statement, a signed lease, or a medical form. Uploading those to a free converter to save four seconds is a bad trade, and it is the default way this job gets done. Everything here runs in the page instead, so the question of what a server does with your file never comes up.
Three things worth doing for that use case:
- Choose A4 or Letter rather than fit-to-image, so the output prints and files predictably.
- Keep the quality slider high. Small print on a photographed document is the first thing to go, and an unreadable submission gets rejected.
- Check the page order before downloading. Phones sort by capture time, which is not always the order the document goes in.
Frequently asked questions
Are my photos uploaded?
No. Images are decoded by the browser, drawn to a canvas, and assembled into a PDF by pdf-lib, all inside this tab. Nothing is transmitted. That matters here more than it sounds: the most common reason to turn photos into a PDF is a document you photographed, which is usually an ID, a receipt, a form, or a signed page.
Can I use iPhone photos?
Yes. HEIC and HEIF files are converted in the browser before they are embedded, so you can drop photos straight from an iPhone without exporting them as JPEG first. Many converters simply reject HEIC.
Should I pick A4, Letter, or fit-to-image?
Fit-to-image gives each page the exact dimensions of its photo, so there are no borders and nothing is scaled. That is what you want for a photo album or a screenshot bundle. Choose A4 or US Letter when the PDF is going to be printed or filed, because a mixed-size PDF prints unpredictably.
Why did my PDF come out bigger than the images?
It usually has not, but a PDF adds a small structural overhead and each image is re-encoded as JPEG, which can slightly grow an image that was already heavily compressed. If the total is larger than you want, lower the image quality slider, which affects photographs strongly and flat screenshots barely at all.
What happens to transparency?
Images are embedded as JPEG, which has no alpha channel, so transparent areas are flattened onto white. For a PNG screenshot with a transparent background, that is almost always what you wanted anyway on a printed page.
