How can I verify the images aren't uploaded?

Open your browser's DevTools (F12) and go to the Network tab, then use the tool. The only requests to a server you may see are for this site's own pdf-lib script files, which load the first time you convert; none of them carries your images. All processing happens in your browser tab using pdf-lib.

Which image formats are supported?

JPEG, PNG, and WebP images are supported. GIF files are also accepted. WebP and GIF images are converted to JPEG before embedding, with transparent areas filled white.

Which files are skipped?

Anything that is not JPEG, PNG, WebP, or GIF, including SVG and HEIC files. The tool tells you how many files it skipped and adds the rest to the list.

Will the image quality be preserved in the PDF?

JPEG images are embedded with their original image data and no re-compression, minus the camera metadata (EXIF including GPS, XMP, IPTC, comments, C2PA, and thumbnails), and PNG images are embedded losslessly. WebP and GIF images, mirrored JPEGs, and JPEGs or PNGs that cannot be read directly are converted to high-quality JPEG before embedding. Each page is sized to match the image dimensions exactly, and the PDF carries no producer, creator, or date properties.

Images to PDF Without Uploading

Convert your images to a PDF entirely in your browser. Our servers are not involved at any point. Drop your JPEG, PNG, or WebP images, arrange them in order, and download the PDF.

How it works

The tool uses pdf-lib, a JavaScript PDF library, to create a new PDF document in your browser. Each image is read from disk, converted to the appropriate format if needed, and embedded into the PDF. JPEG images are embedded without re-encoding after their metadata (EXIF including GPS, XMP, IPTC, comments, C2PA, and thumbnails) is removed. PNG images use pdf-lib's PNG embedding, which keeps only the pixels. A rotated EXIF orientation in a JPEG or PNG is applied by rotating the page, and a mirrored, animated, or incomplete PNG is redrawn as PNG on an HTML canvas. WebP, GIF, mirrored JPEGs, and JPEGs or PNGs that cannot be read directly are drawn onto an HTML canvas and exported as JPEG first, with transparent areas filled white. Each page is sized to match its image exactly.

Processing runs in your browser

All processing happens locally in your browser tab. pdf-lib builds the PDF in memory, and our servers are not involved at any point.
