Frequently asked questions
No. Everything happens in your browser with pdf-lib. Image bytes never leave your device.
Yes. HEIC files are decoded with libheif WebAssembly and re-encoded as JPG before being embedded in the PDF.
Up to 100 per batch. Memory limits depend on your device — a phone will handle fewer large photos than a desktop.
JPEG images are embedded as-is (no re-encode). PNG and WebP are converted to JPEG at high quality to keep PDFs reasonably small.
No. EXIF is stripped during conversion. Use our EXIF Viewer first if you want to inspect what was on the original.
About image-to-PDF
Generating a PDF from images is a two-step process: decode each image to raw pixels, then embed it into a PDF page that’s sized correctly for print. pdf-lib handles the embedding side, and the browser’s Image + canvas APIs take care of decoding and any re-encoding required.
Page sizing
- A4 / Letter / Legal / A3 / A5 — fixed page sizes; each image is centered with the chosen margin.
- Fit to image — each page matches the image’s exact aspect ratio. Best for documents that should not be cropped.
Orientation
Auto picks portrait or landscape per image. Forced portrait or landscape rotates the page so the image fits without being cropped.
