ConvertWarp

Image to PDF

Put JPEG, PNG, or WebP images on PDF pages. JPEG and PNG stay as they are. WebP uses the first frame.

PDF tools use pdf-lib (MIT).

About this tool

This binder puts JPEG, PNG, or WebP stills onto PDF pages — one image per page — in the order you add them. Use it for a packet of scans when you do not already have PDFs to merge.

JPEG and PNG are embedded. WebP is not a native PDF image, so the first frame is placed as a raster the PDF can hold. Mixed sizes keep their own page dimensions.

Each file is sniffed locally and written into one PDF with pdf-lib. 50 MB per file and 32 megapixels per still. Password-protected inputs are not a feature here.

How to convert images to PDF

  1. Add JPEG, PNG, or WebP files in the order you want the pages. They stay on your device.
  2. Convert. Each still becomes one page.
  3. Download the multi-page PDF in the order you added files.

50 MB per image, 32 MP each. HEIC must be converted first. This is not OCR and not a merge of existing PDFs.

FAQ

Are the pictures uploaded?
No. The PDF is built in the tab.
What happens to WebP animation?
The first frame is used. Motion is dropped.
Can I reorder pages after?
Yes — Reorder PDF pages once you have a PDF. Or add the stills in the right order now.
JPEG vs PNG in the same PDF?
Allowed. Each page keeps its own encoding.
How is this different from Merge PDF?
Merge PDF joins PDF files. This page starts from pictures.
