Features
The Image to PDF tool converts JPG, JPEG, PNG and WebP images to PDF (BMP, GIF and HEIC are not supported). Select up to 20 images at once, set their order, then generate a multi-page PDF with one image per page. Page size can be Fit to image, A4 or Letter (A4 by default); orientation can be Auto, Portrait or Landscape; margins can be None, Small (20pt) or Large (40pt). Photos are rotated according to their EXIF orientation, and small images are never upscaled. The entire process runs locally in your browser — your photos are never uploaded to a server. Common use cases: combining scanned receipts into one PDF for archiving, converting ID photos to PDF for online applications, assembling design screenshots into presentation documents.
