SnapPDF — JPG to PDF Converter, Free, Online, No Upload

Turn a folder of images into one PDF, on your own device

SnapPDF is the image-to-PDF converter on this page. Choose your images, drag them into the order you want, and export them as a single PDF — one image per page. JPG and PNG both work, and you can mix them in the same document.

That covers the usual jobs under their usual names: convert JPG to PDF online free, turn multiple JPG images into one PDF, or use it as a free image to PDF converter when the source is PNG rather than JPG. Convert images to PDF in a particular order by dragging them into place before exporting — the page order in the finished document is the order shown on screen — and to combine images into a PDF as a single file, add them all before you export rather than exporting one at a time.

The conversion runs entirely in your browser. Your images are never sent to a server, which matters more here than it does for most tools: the things people convert to PDF are usually scanned documents, ID photographs, receipts and contracts. None of that leaves your device, and there is nothing on our side to leak.

A note on size: a PDF built from photographs inherits their resolution, so a dozen phone pictures can produce a file of several megabytes. If you are attaching the result to an email, resize the images before converting rather than after — a PDF cannot be made smaller without re-encoding what is already inside it.

Crop, rotate and straighten before you export

A photograph of a document is rarely square to the page. Crop away the desk and the shadow around the edges, rotate in ninety-degree steps when the picture came out sideways, or nudge the fine rotation a degree or two to straighten a scan that sits crooked. You can also flip an image horizontally or vertically. Every one of these is applied to the exported PDF, not just to the preview.

Fix contrast, brightness and colour on a scanned document

This is the part most image-to-PDF converters leave out. A page photographed under a room light comes out grey and flat; raising the contrast and dropping the brightness turns it back into black text on white paper. There are controls for brightness, contrast, saturation, hue and invert, white balance for a photo that came out too warm or too blue, and vibrance, highlights, shadows, clarity and sharpness for finer work. Adjust until the text is readable, then export — the PDF carries the corrected image, not the original.

Sign a scanned document, or add text and shapes

Draw a signature or your initials and place it where it belongs, stamp today's date, tick a checkbox, highlight a line, or type text anywhere on the page with a choice of font, size, weight, colour and alignment. Shapes — rectangle, circle, arrow, triangle, star, heart and hexagon — can be dropped on top to point at something or box it off. All of it is drawn into the finished PDF, so the person who opens it sees one flattened document rather than an image with notes floating over it.

Page size, orientation and margins

Export to A4 or US Letter, portrait or landscape, or let the page fit the image so there is no white border at all. The margin width is yours to set: wide for something that will be printed and punched, none for a photograph that should fill the sheet. Images are centred inside the margin and scaled to fit without distorting their proportions.

Nothing is uploaded

SnapPDF runs entirely in your browser. There is no upload step, no queue, and no copy of your file on a server afterwards — which is the point, because the things people convert to PDF are ID cards, bank statements, contracts and medical letters. It also means there is no file-size limit imposed by a server and no wait: the work happens on your own machine, at the speed of your own machine.

Questions

Is SnapPDF free?

Yes — free, with no account, no watermark on the PDF and no limit on how many times you use it.

Can I put several images into one PDF?

Yes. Add them all before exporting, drag them into the order you want, and you get one PDF with one image per page in that order.

Does it work with PNG as well as JPG?

Yes, and you can mix JPG and PNG in the same document.

Are my images uploaded anywhere?

No. The conversion runs in your browser and the images never leave your device.

Can I add a signature to a scanned document?

Yes. Draw a signature or initials, place them on the page, and they are drawn into the exported PDF.

Does SnapPDF do OCR, or merge and compress existing PDFs?

Not yet. Today it converts and edits images on their way into a PDF; it does not read text out of them or open a PDF you already have. Those tools are listed as coming in the menu, and they are not pretending otherwise.
