Image to PDF Converter
Combine JPG and PNG images into one PDF — reorder, page-fit or A4/Letter, all in your browser
Add images to build a PDF — HEIC/HEIF is not supported.
Examples
Receipt bundle
5 phone photos → A4, 24 pt margin, auto-rotatereceipts.pdf — one receipt per page, oriented for paperLandscape shots rotate the page, not the image — no sideways pixels.
About this tool
Combines JPG and PNG images into one PDF with pdf-lib, embedding the original bytes — no re-compression, no decode/re-encode step. Page geometry is your choice: fit-to-image (each page exactly the image's pixel size) or A4/Letter with a margin and optional auto-rotate for landscape shots.
HEIC/HEIF is rejected with a clear message up front, because browser Canvas and pdf-lib lack a free HEIC codec — an honest refusal beats a silently blank page.
How to use

Photograph receipts, order them, hand in one PDF.

Common mistakes
Mistake:Adding HEIC photos directly from an iPhone
Fix:Convert to JPG first — the tool rejects HEIC explicitly rather than emitting blank pages.
Mistake:Expecting compression
Fix:Output size ≈ sum of inputs; images are embedded at original quality.
