Convert images to PDF

Runs on your device — nothing is uploaded

Turn a folder of photos or scans into a single tidy PDF. Each image becomes one page, sized to match the image itself.

How it works

1. Add your imagesDrop JPG, PNG or WEBP files. They are added in the order you pick them.
2. Check the orderPages follow the list order. Remove anything you added by mistake.
3. Create the PDFOne page per image is created, sized to the image dimensions in points.

How page size is decided

Each image becomes its own page, sized to the image's own proportions and scaled from pixels to PDF points at 72 points per inch. Nothing is cropped, nothing is letterboxed onto an A4 sheet, and no white margin is added. That keeps receipts, tickets, screenshots and phone photos at their natural aspect ratio.

The practical consequence is that a mixed set produces mixed page sizes within one document. Most viewers and printers handle that without complaint, but if you need every page to be A4 — for example when submitting to a portal that enforces a paper size — convert the images to A4 in an image editor first, since this tool deliberately does not invent margins or padding.

Making a document out of photos

The far and away most common use is turning phone photos of paperwork into a single PDF: a stack of receipts for expenses, pages of a signed form, a passport, a handwritten inventory, or a whiteboard after a workshop. Photograph each item straight-on with even lighting, crop any desk visible around the edges, then add them here in the order you want.

Because WEBP, GIF and BMP cannot be embedded into a PDF directly, those formats are drawn onto a canvas and re-encoded as JPEG automatically. That is lossless for nothing, but it is the only way to get a format the PDF specification actually supports.

Keeping the file small

A PDF made from photos is as large as the photos themselves. A modern phone camera produces 3 to 6 MB per shot, so forty photos make a 150 MB PDF that no email service will accept. Either choose a smaller export size in your phone's camera settings, resize the images before adding them, or run the finished PDF through the Compress tool and pick the Strong level.

Questions

Which formats are supported?

JPG, PNG and WEBP natively. Other formats the browser can decode, such as GIF and BMP, are converted to JPEG automatically.

Can I change the page size or add margins?

Pages are created at the exact pixel dimensions of each image, with no added margins or padding. That keeps scans and receipts predictable when printing.

Is there a limit on the number of images?

No fixed limit. Large photo sets depend on your device memory, so a few hundred images at phone resolution is a reasonable ceiling.

Will my iPhone HEIC photos work?

Safari can decode HEIC, so the automatic JPEG conversion handles them there. If your browser cannot decode HEIC, export the photos as JPG first.

Does the image quality change?

JPG and PNG images are embedded as-is with no re-encoding. Only formats the PDF format cannot hold — WEBP, GIF, BMP — are converted, and those go through a canvas as high-quality JPEG.

Can I rotate an image before adding it?

Rotate it in your phone's or computer's photo viewer first. The tool deliberately does not re-encode the images it embeds, so rotation is not offered here — use the Rotate PDF tool afterwards instead if the finished document needs it.
