Choose files

Whatever you have, into one PDF

If your files are all JPGs, the dedicated page explains the trade-offs in more detail. If they are a mixture, which is what a folder of things photographed and downloaded over a week usually is, drop the lot here. Anything your browser can open becomes a page.

That covers JPG, PNG, WebP, AVIF, BMP, GIF and JFIF everywhere, and HEIC in Safari. A JPEG is carried into the PDF exactly as it is, with nothing decoded and nothing lost. Anything else is drawn and encoded once at a high quality, because those are the only pictures a PDF can hold.

Put the pages in the order you want, pick the paper size, and download a single file. None of it leaves your device.

Images in several formats being combined into one PDF document
How it works

Three steps, no upload

Your browser reads the images and writes the document. There is no queue and no waiting.

1

Add your images

Drop in as many image files as you like, or pick them from your device.

2

Put them in order

Each row is numbered and has arrows. The order you see is the order the pages will be in.

3

Build the PDF

Choose the page size and margin, then download one document. Nothing was uploaded to get it.

How an image becomes a page

A PDF carries a JPEG stream natively, under a filter called DCTDecode, and nothing else. So a JPG among your files is placed in the document exactly as it is, with no decoding and no loss at all.

Every other format has to become one. A PNG, WebP, AVIF, BMP or GIF is decoded by your browser, drawn onto a canvas over white, and encoded once at a high quality before it goes in.

The page itself is described in points, the unit a PDF measures in, at seventy two to the inch. An A4 page is 595 by 842 of them. Your image is scaled until one edge meets the margin, centred, and drawn. Its proportions are never changed, because a stretched photograph of a document is worse than a small one.

The last part of the file is a table of byte offsets, one for every object in it. That table is why so many hand written PDFs fail to open: if a single offset is wrong the reader gives up and shows nothing. Ours is checked against the finished file on every build.

Choosing the page size

SettingSizeWhen to use it
A4210 x 297 mmThe default nearly everywhere outside North America, and what almost every upload form expects.
Letter8.5 x 11 inThe standard in the United States and Canada. Slightly wider and shorter than A4.
Legal8.5 x 14 inLonger paper for contracts and legal filings in North America.
A5148 x 210 mmHalf of A4. Useful for booklets and for keeping a document small on screen.
Fit the page to the imageWhatever your picture isNo scaling and no white border at all. Right for screenshots that will only be read on a screen.

Orientation is set to match each image by default, so a landscape photograph gets a landscape page and a portrait one gets a portrait page, in the same document. Forcing one or the other is there for when the pages have to match, such as a form that will be printed.

The margin is white space between the picture and the edge of the paper. None fills the sheet completely, which suits scanned pages. Normal leaves a border that looks right when printed. If in doubt, leave it alone.

Why none of this leaves your device

Think about what people actually turn into PDFs. Passports and visas. Bank statements for a loan application. Degree certificates. Rental agreements with a signature on them. Medical letters. Almost every one of those is a document you would not hand to a stranger.

An online converter that works the ordinary way asks you to do exactly that. Your file goes to a server you know nothing about, in a country you were not told, and is processed and stored for some period described in a policy nobody reads. Most of those services are honest. You have no way of checking which ones.

This page removes the question. The conversion runs in your browser, using the image decoder your browser already has and a PDF writer that is part of the page. No file is transmitted, so there is nothing on our side to store, scan, sell or lose. You can disconnect from the internet after the page loads and it will still work, which is the simplest proof there is.

Before you build it

  • Order matters and is yours to set. Files arrive in the order you dropped them; the arrows move them.
  • Each image becomes one page. Nothing is tiled or combined, so ten images make a ten page document.
  • Transparency becomes white, because a PDF page is opaque.
  • The size of the PDF is the size of the pictures. Compress them first if there is a limit to meet.
  • An animated GIF contributes its first frame. A PDF page does not move.

Choosing the page size

A4 is right for anything that might be printed or submitted, and Letter for North America. The option worth knowing about is the last one: make the page exactly the size of the image. It means nothing is scaled and no white border appears, which is what you want for a set of screenshots that will only ever be read on a screen.

How this compares with the alternatives

An online converter that uploads

Faster to build and slower to use: your file has to travel to a server, wait its turn, be converted and travel back. On a phone connection a folder of photographs can take longer to upload than the whole job takes here. And the file is then somewhere you cannot see.

The print to PDF option on your computer

Both Windows and macOS can print an image to a PDF, and for a single file that is a perfectly good answer. It becomes awkward at more than one: you cannot easily control the order, each image tends to become its own document, and combining them afterwards needs another tool.

A phone scanner app

Genuinely better when the source is a physical page, because it will straighten the photograph, crop to the paper and lift the contrast. Use one for scanning. Come here when you already have the images and simply need them in a document.

A full editor such as Acrobat

The right tool when you need to edit, sign, redact, merge existing PDFs or fill a form. That is a different job from making one, and it is not what this page claims to do.

If something does not look right

The pages came out in the wrong order

Files are added in the order the browser hands them over, which for a multiple selection is not always the order you clicked. Every row is numbered and has arrows, so set the order before you build rather than after.

There is a white border I did not want

That is the margin. Set it to none, or choose to fit the page to the image, which makes the page exactly the size of the picture and leaves no border at all.

The image looks small on the page

A picture is scaled to fit inside the margins without changing its shape, so a very wide photograph on a portrait page leaves space above and below. Set the orientation to match each image, or fit the page to the image.

My iPhone photos will not open

iPhones save as HEIC, and only Safari can decode it. On an iPhone or a Mac this page will read them normally. In Chrome or Firefox on a desktop it cannot, because the browser has no HEIC decoder. Convert them with our HEIC to JPG page in Safari first, or set your iPhone to save as JPEG under Settings, Camera, Formats, Most Compatible.

The PDF is bigger than I expected

It will be about the size of the images that went into it, because they are not recompressed. Ten photographs of four megabytes make a forty megabyte PDF. Compress them first if there is a limit.

My scan is sideways

Some cameras record the rotation as metadata rather than rotating the pixels, and not every browser applies it. If a page comes out on its side, rotate the image in your photo app and drop it in again.

Free, with no account and no watermark

There is no sign-up, no daily limit and no watermark stamped across the corner. There is no paid tier holding back the page size or the number of files, because the conversion costs us nothing to provide: it runs on your computer, not ours.

The downloaded file keeps your own name. One image called passport-front.jpg becomes passport-front.pdf, and several files become converted.pdf. Nothing is added to the name and nothing is added to the document.

If you need the PDF smaller, compress the images before you build it. Our image compressor takes an exact target in kilobytes, and a PDF built from smaller pictures is a smaller PDF. That is the only lever there is, because nothing else in the file is large enough to matter.

FAQ

Image to PDF

The questions people ask most about this conversion.

JPG, PNG, WebP, AVIF, BMP, GIF and JFIF in every browser, plus HEIC in Safari. Anything your browser can display can become a page.

Yes. Drop JPGs, PNGs and anything else together and each becomes a page of the same document.

Yes. Each file has an up and a down arrow, and the numbering shows exactly what order the PDF will be built in.

No. Everything runs in your browser, so no file is sent anywhere and there is nothing on our side to store or delete.

Only your device's memory. Dozens of pages are ordinary; a few hundred large photographs will make a very large file.

Completely, with no limit on how many images you convert or how large they are. There is no account, no paid tier and no watermark, because the conversion runs on your device and costs us nothing to provide.

No. There is no app, no extension and no plugin. The page you are on is the whole program, and it works the same on Windows, macOS, Android and iPhone.

No. There is no watermark, no logo and no added page, however many images you convert.

Yes, on both iPhone and Android. Pick images straight from your gallery and the PDF is saved to your downloads like any other file.

No. This page makes a PDF out of images. Reading an existing one needs a full PDF renderer, which is a large program we would have to load from somewhere else, and that would break the promise that nothing leaves your device.
