How to convert Images to PDF

  1. 1

    Add images in any mix of formats.

  2. 2

    Arrange them into page order.

  3. 3

    Combine into one PDF.

Use this when your images are not all the same format. A real folder tends to be a jumble — a couple of phone photos, a screenshot, something saved from a website that turned out to be WebP — and the JPG and PNG pages each expect one format. This page takes whatever you have.

Two paths through the converter

JPEG and PNG are embedded directly. PDF supports both natively, so their compressed bytes go into the document untouched, with no re-encoding and no quality loss whatsoever.

WebP, AVIF, GIF and BMP cannot be embedded, because PDF has no idea what they are. Those are decoded and re-encoded as PNG first. That step is lossless — nothing is degraded — but PNG is an inefficient way to store a photograph, so a WebP photo can become several times larger inside the PDF than it was on disk.

If document size matters and your images are photographic WebP or AVIF, convert them to JPG before assembling the PDF. You will get a far smaller file, and you get to choose the quality rather than accepting PNG's bulk.

Ordering is the part people get wrong

  • The list is the page order. Arrows move images up and down.
  • File pickers return files alphabetically, so IMG_10 lands before IMG_2.
  • Images added later append to the end rather than disturbing what you arranged.
  • For a photographed document, check the order before combining — pages out of sequence are the most common reason a submission gets rejected.

Page size

By default each page is exactly the size of its image, so nothing is scaled or padded and mixed orientations look natural. Choose a paper size when the result will be printed, and every image is centred on that page with a margin, scaled to fit while keeping its proportions.

One thing this cannot do

The text in your images stays an image. A photographed or screenshotted page goes into the PDF as a picture of text — not selectable, not searchable, and not readable by a screen reader. Making it real text requires optical character recognition, which is a different operation from format conversion and is not what any image-to-PDF tool does, whatever it implies.

Everything runs in this tab. No file count limit, no size cap, nothing uploaded.

Photos of documents are still photos

A phone photograph of a page is rarely as good as a scan, whatever the megapixel count. Uneven lighting, a slight angle and the shadow of your own hand all survive into the PDF. If the document matters, photograph it flat in even light, or use a scanner app that corrects the perspective before you bring the images here.

Questions about Images to PDF

Which image formats can I mix?

JPG, PNG, WebP, AVIF, GIF and BMP, all in the same document. JPEG and PNG are embedded directly; the others are converted to PNG first, losslessly.

Why did my WebP images make the PDF so large?

PDF cannot embed WebP, so those images are converted to PNG — lossless, but inefficient for photographs. Converting photographic WebP to JPG before assembling gives a much smaller document.

Is any quality lost?

None. JPEG and PNG go in untouched, and the other formats are converted losslessly to PNG. Nothing is re-compressed at any point.

How do I get the pages in the right order?

Use the arrows in the list, which shows the exact page order. Alphabetical file ordering puts IMG_10 before IMG_2, so it is worth checking before combining.

Will the text in my screenshots be searchable?

No. Images of text stay images. Making it searchable requires optical character recognition, which is a separate operation from converting formats.

Should I set a page size?

Set one if the PDF will be printed. Leave it unset and each page matches its image exactly, which suits screenshots and anything staying on screen.
