Image to PDF

How it works — and why it's private

Drop in your images, put them in order with the Move buttons, pick a page size, and click Create PDF. The PDF is assembled by JavaScript running on your device: the jsPDF library loads from this site — never a third-party CDN — the moment you click Create, and your images are never uploaded anywhere. No account, no watermark, no page limit. You can load this page, disconnect from the internet, and it still works.

The full source code is public on GitHub (AGPL-3.0), and the privacy panel in the footer lists everything this page loads.

Page sizes, explained

Fit to image (the default) makes each PDF page exactly the size of its image — edge to edge, no borders, no scaling. A4 and Letter make every page a standard paper size: the page turns sideways to match each image (a landscape photo gets a landscape page), and the image sits centered inside a half-inch (36 point) margin. Images are scaled down to fit the page when needed, but never enlarged past their natural size — so nothing gets blurry.

Quality: what changes, what doesn't

JPEG files are embedded byte-for-byte — the PDF carries your original JPEG data with no re-compression, so there is zero quality loss. PNG files are embedded as PNG, also lossless; transparent areas simply show the white page behind them. Two exceptions, each labeled on the file's row: WebP images are converted to high-quality JPEG (92%) because PDFs can't hold WebP, and JPEGs carrying an EXIF rotation flag are rotated and re-encoded (92%) — PDF viewers ignore that flag, so embedding those untouched would leave the page sideways.

One honest side effect of embedding JPEGs unmodified: any metadata inside them — camera model, GPS location — travels into the PDF too. If you'd rather it didn't, run the photos through our Remove EXIF data tool first, then build the PDF.

Questions

Are my images uploaded to a server?

No. The PDF is built in your browser using JavaScript this page loads from its own site. You can verify: open your browser's DevTools Network tab while using the tool — no image data leaves your device.

Which page sizes can I choose?

Fit to image (each page matches its image exactly), A4, or Letter. On A4 and Letter, page orientation follows each image, and images are centered inside a 36-point margin without ever being upscaled.

Does the PDF reduce my image quality?

Not for most files — JPEGs are embedded without re-compression, byte for byte, and PNGs stay lossless. Re-encoding (once, to JPEG at 92% quality) happens only for WebP, which PDFs can't contain, and for JPEGs whose EXIF rotation flag would otherwise leave them sideways — the row tells you when.

Can I change the page order?

Yes. Every image row has Move up and Move down buttons; the PDF pages follow the list order exactly. There's a Remove button on each row, too.

What about HEIC photos from iPhones?

PDFs (and this tool) can't read HEIC directly. Convert them with our free HEIC to JPG tool first, then add the JPGs here.
