Images to PDF
Turn JPG and PNG images into one PDF, with page size, orientation, margin and fit controls.
Images
Everything runs in the browser; files are never uploaded. Chinese page numbers and watermarks are embedded as bitmaps, so they soften when zoomed — Latin text and digits stay vector.
Technical notes and known limits
pdf-lib (MIT) rewrites documents; PDF.js (Apache-2.0) renders and extracts text. Both load only when you start. Icons plus runtime cmaps and standard fonts come from jsDelivr. Chinese page numbers and watermarks are drawn on a canvas because embedding a CJK font would mean a multi-megabyte download. Encrypted PDFs are opened with the restriction ignored; whether that works depends on the encryption.
