Practical PDF, image, developer, and everyday tools

Clearly labeled processing for everyday tasks.

Core processing runs in the browser for most tools. Server-backed and external-provider workflows are labeled separately. Basic tools are available without signup; individual limits vary by tool.

Image to PDF Converter

  • In-browser
  • No signup
  • Combine images

Build one ordered PDF from mixed supported image formats, with one ready image on each page.

Core processing runs in your browser and does not upload this file for the task.

What this tool does

Image to PDF builds one PDF from mixed supported still images. ImageToPdf.jsx is a re-export of JpgToPdf.jsx with slug image-to-pdf.

When to choose it instead of a similar DevToolKit tool

  • Use this for PNG screenshots, WebP, GIF, or BMP alongside JPEG.
  • Use JPG to PDF if you want the JPEG-only dropzone.
  • Photo Collage exports one raster image, not a multi-page PDF.

Typical jobs this page is built for

  • Combine mixed stills into one PDF in arrow-control order.
  • Keep PNG screenshots as PNG-in-PDF pages.
  • Use Fill when you want the image to cover the page and can accept cropping.

Supported inputs, limits, and output behavior

Formats
JPEG, PNG, WebP, GIF, BMP (type or extension).
Limits
40 files, 20 MB each, 100 MB total — same constants as JPG to PDF.
Pages
One ready image per page; failed items can be marked error at inspect.

How the transformation actually works

JPEG → embedJpg. PNG → embedPng of source bytes. Other types → canvas PNG → embedPng. Page geometry matches JPG to PDF: Auto 595.28 width, height 280–1200; A4 595.28×841.89; Letter 612×792; orientation can swap width/height.

Step-by-step workflow

  1. Click Choose images or drop mixed stills within the count and byte limits.
  2. Move items with Move earlier / Move later.
  3. Pick a layout preset, then override page size, fit, orientation, or margin if needed.
  4. Edit File name if you do not want the default.
  5. Click Create PDF.
  6. Open the downloaded PDF and inspect each page.

What can change in the output

Canvas-converted pages are PNG-in-PDF, which can be larger than the source WebP. Fill can crop. Metadata from the images is not copied as PDF document metadata beyond what pdf-lib writes by default.

Known limitations and failure cases

  • HEIC is not in IMAGE_ACCEPT.
  • A type the browser cannot draw fails with a canvas/read error.
  • No selectable text, no bookmarks.

Privacy / where data goes

Processing is local pdf-lib plus canvas for non-JPEG/PNG types. Images are not uploaded for this conversion. Identified analytics may include file counts and layout settings, not the image pixels.

Practical output-review checklist

  • Check mixed page sizes on Auto.
  • Look at GIF/WebP pages for the expected still frame.
  • Verify Fill did not clip needed edges.
  • Confirm the download has one page per ready image.

Frequently asked questions

What happens to WebP, GIF, or BMP pages?

fileToEmbedBytes draws them to a canvas and toBlob image/png, then embedPng. GIF/WebP animation is not preserved; the Image element supplies the frame it loads. Transparency can survive in the PNG embed when the canvas has alpha.

Is HEIC accepted here?

No. IMAGE_ACCEPT is JPEG, PNG, WebP, GIF, and BMP (type or extension). Convert HEIC on HEIC to JPG first, then add the JPEG here.

How many images can I add?

1–40 files, 20 MB each, 100 MB combined — the same constants as JPG to PDF. Failed items can be marked error at inspect. One ready image becomes one PDF page in list order.

Does JPEG stay JPEG inside the PDF?

Yes. JPEG uses embedJpg of the source bytes. PNG uses embedPng of the source bytes. Other types become canvas PNG, which can be larger than the source WebP.
