How to use this JPG to PDF converter

Each image is decoded, redrawn on a canvas and placed on its own page by jsPDF, all inside your browser.

Updated for 2026: build progress with Cancel, and a preview before you download
  1. 1

    Add in any order

    Drop images in one go or a few at a time. Each one is numbered with its page number.

  2. 2

    Fix the order

    Use the up and down arrows on each card. Page 1 is the top-left card.

  3. 3

    Rotate sideways scans

    Tap rotate to turn an image 90° at a time. The page follows the new shape.

  4. 4

    Pick the layout last

    A4, Letter or Legal for printing, or fit to image for pages the size of each photo.

Guide

Getting a clean PDF every time

Four habits that make the PDF look right the first time.

Source

Start with sharp photos

The PDF keeps the pixels you give it. A blurry phone photo stays blurry on the page.

  • Good light, flat page
  • Fill the frame
  • Avoid zoomed screenshots
Rotation

Check the thumbnails

Phone rotation tags are applied for you. Rotate by hand only what still looks sideways.

  • Look at every card
  • Rotate in 90° steps
  • The page turns too
Layout

Match the paper

If someone will print it, use the paper size they print on. A4 in most countries, Letter in the US.

  • A4 for most of the world
  • Letter or Legal for the US
  • Fit to image for screens
Check

Preview before saving

The PDF opens in the studio first, so you can page through it before you download.

  • Page through it
  • Edit and rebuild
  • Then download
Options

Page sizes, orientation and margins

What each setting does to the pages in your PDF.

A4

210 x 297 mm, the ISO 216 paper size used across most of the world.

Letter

8.5 x 11 inches, the usual paper size in the US and Canada.

Legal

8.5 x 14 inches, a taller US size used for some forms and contracts.

Fit to image

Each page takes its image's shape, sized at 150 DPI and capped at 1189 mm, the long side of A0.

Auto orientation

Wide images get a landscape page and tall ones a portrait page, page by page.

Margins

None, or 5 mm, 10 mm, 20 mm of white space around each image. The image is centred.

Guide

How different people use it

One studio, very different documents.

Typical setting: A4 · small margins · check the portal's size limit

Students

Handwritten work

Photograph each page of an assignment and hand it in as one PDF.

Typical setting: A4 · portrait · medium margins

Expense claims

Receipts in one place

Snap every receipt from a trip and send one PDF to accounts.

Typical setting: auto orientation · small margins

Photographers and designers

Simple portfolios

A clean PDF of selected shots, each page shaped like its photo.

Typical setting: fit to image · no margins

Guide

Keeping your scanned documents tidy

A few habits that save you from rebuilding the same PDF.

  1. 1

    Keep the originals

    Save the photos as well as the PDF. The Originals (ZIP) button bundles them in one file.

  2. 2

    Rename on save

    The PDF is named images-to-pdf with the date and time. Rename it to say what is inside.

  3. 3

    One PDF per purpose

    A separate PDF for each form or claim is easier to find and to re-send.

  4. 4

    Rebuild, don't patch

    Missed a page? Add it, move it into place and convert again. It takes seconds.

Pro tips

Pro tips for image PDFs

Small checks that make the PDF look right first time.

Mixed shapes? Use Auto

Auto gives each wide photo a landscape page, so it isn't shrunk onto a tall page.

Edge to edge

Pick fit to image with no margin for pages that are exactly the photo.

Phone photos

Rotation tags are applied, so most phone photos come out upright without help.

Logos and screenshots

PNGs go in losslessly, so text and sharp edges stay crisp.

Back up the originals

Originals (ZIP) saves the images you added, not the PDF.

Use the preview

Page through the preview before downloading. Changing a setting clears it, so build again.

Private scans

ID cards and statements are never uploaded. The PDF is built on this page.

Need it smaller?

Run the PDF through Compress PDF for a size limit.

Pro tip: order first, layout second

Get the page order right before you choose a page size. The order is the hard part to spot in a finished PDF; the layout you can see at a glance in the preview.

Which one

Fit to image, or a fixed paper size?

Fit suits screens. A fixed size suits printers and forms.

Forms · printing · sharing
A4fixed size

A4, Letter or Legal

Every page is the same paper size, and each image is scaled to fit inside the margins and centred.

When it may be printed

Portfolios · screens · slides
Fitimage shape

Fit to image

Every page is the shape of its photo, so there is no extra white space beyond the margin you pick.

When it stays on screen

Verdict: pick A4 (or Letter in the US) for anything that may be printed or uploaded to a form, and fit to image for photo sets people will only look at on a screen.

FAQ

Frequently asked questions

Quick answers about formats, page sizes, order and privacy.

Does PNG to PDF preserve transparency?
PNG transparency is kept in the PDF (jsPDF writes it as a soft mask), so transparent areas show the white page behind them. Colours are kept.
