Image to PDF Converter

These days documents get photographed with a phone rather than run through a scanner. Hardly anyone owns a scanner, and a photo taken square-on in good light reads perfectly well. The trouble starts afterwards. Snap both sides of an ID, a bank statement and a four-page contract and you're holding seven photos — while the upload form wants exactly one file, or caps attachments at three. Bank applications, expense reports, school paperwork and visa forms hit this wall constantly.

Even where multiple files are accepted, the order rarely survives. The recipient's screen usually sorts by file name, so pages you carefully uploaded as 1 through 4 arrive shuffled. For anything that has to read in sequence — a contract, most obviously — that alone can get a submission bounced. Combine everything into one PDF and the page order is locked inside the file: it opens the same way for everyone, everywhere.

Email is easier too. Seven photos mean seven downloads and seven clicks for whoever receives them; a PDF is one click and a scroll. Same for printing — image files go through the print dialog one at a time, while a PDF prints end to end in one pass.

Match image size uses each image's pixel dimensions as the page size — a 1200-pixel-wide photo becomes a 1200 pt-wide page. Nothing is cropped and no white space appears, so for documents that will only ever be viewed on screen, this is the cleaner choice. The trade-off: every page can be a different size, and a modern 3000×4000-pixel phone photo produces a nominal page over a metre tall. Viewers scale it to fit so you'd never notice on screen, but when printing you must pick "Fit to page" in the print dialog to land it on a single sheet.

Choose A4 or Letter and every page comes out the same size — the safe option for anything meant to be printed or filed. Just don't expect photo and paper proportions to match: A4 is roughly 1:1.414 while phone photos are usually 3:4, so a 3:4 photo on a portrait A4 page leaves white bands top and bottom. This tool never crops the image to fill that space. In a document photo, cropping means losing content, so a fill-the-page mode was deliberately left out.

With orientation set to Auto, wide photos land on landscape pages and tall ones on portrait pages — the least wasted space when portrait documents and landscape receipts are mixed together. If the PDF is headed for a printer and a binder, though, alternating orientations are a nuisance; lock it to portrait or landscape instead.

Margins are converted precisely. PDF measures in points, and 1mm = 72/25.4pt, so a 10mm margin goes in as 28.3465 pt. That said, what lands on paper is decided by your printer settings. If "Fit to page" or "Fit to printable area" is on, the printer shrinks the whole page a few percent to dodge its unprintable edge, and your 10mm margin prints closer to 12mm. When physical size matters, choose "Actual size" or 100% scale in the print dialog. This tool only guarantees the coordinates inside the PDF — the rest is up to the printer. It also doesn't follow archival profiles like PDF/A, so if a recipient mandates a specific standard, use the method they prescribe.

This is misunderstood remarkably often. PDF is not a compression format — it's a container. Your photos aren't recompressed; the original JPEG data is dropped in whole, with an instruction attached saying "draw this picture here, at this size". Five 4MB photos therefore make a PDF of roughly 20MB — slightly more, in fact, once the PDF scaffolding is added. That's a feature, not a flaw: recompressing would have smeared the text.

PNG behaves a little differently. PNGs are re-encoded losslessly, and the result can end up larger than the original file — especially when the PNG holds a photograph. Photos were never a good fit for PNG to begin with, and putting them in a PDF makes them bigger still. For anything that's a photo rather than text or line art, JPG beats PNG on every count.

If you're bumping into an upload size limit, flip the order of operations. There's no good way to shrink a PDF after the fact. Run the photos through the image compressor first, then combine the results here. Five pages against a 10MB cap means about 1.5MB per photo with room to spare — document photos stay perfectly legible even at fairly aggressive compression.

Camera angle matters most. Shoot from directly above with the camera parallel to the paper and the sheet comes out as a proper rectangle. Shoot at an angle and it skews into a trapezoid — and this tool does not straighten perspective for you. The photo goes onto the page exactly as taken, so reshooting is the quickest fix. Put the paper on a desk rather than the floor, keep a window to your side so your body doesn't cast a shadow, and it will usually come out square.

Margins make a surprising difference too. A PDF filled edge to edge looks bold on screen but loses its borders on most home printers, which physically can't print the outer 3–5mm of the sheet. Even Narrow (10mm) eliminates the problem — and makes the result look much more like a flatbed scan, which always leaves white space around the original.

Tidy the background as well. Wood grain or a stray fingertip in frame gives the photo away no matter how straight it is. White paper on a plain dark surface gives crisp edges — better looking, and easier to crop later.

When you pick several files in the file dialog, the order the browser hands them over is usually file-name order, not the order you clicked them. Click 1, 3, 2 and they still arrive as 1, 2, 3 — and if the order you want doesn't match the names, there's nothing you can do about it at that stage. The exact behaviour even varies by operating system and browser.

Worse, plain file-name sorting doesn't match how people count. It compares character by character, so IMG_10 comes before IMG_2, and 1.jpg is followed by 10.jpg and only then 2.jpg. This tool's "Sort by file name" compares the numbers inside names as numbers, giving you 1, 2, 10. If you're still on the camera's default file names, that one button usually fixes everything.

If anything is still out of place, use the up/down arrows in the list. Drag-and-drop was left out on purpose: on a phone, dragging list items fights with page scrolling, and photographing a document and submitting it on the spot almost always happens on a phone. So: buttons.

It says my WebP will lose a little quality

The PDF specification has no slot for WebP. JPEG and PNG can be embedded byte-for-byte, but WebP can't, so WebP files — and only those — are converted once to JPEG at quality 92 on the way in. For a document photo the difference won't be visible, but it isn't strictly lossless. If you have the original JPG, use that instead. WebP transparency is filled with white.

My iPhone HEIC photos won't load

Chrome and Firefox can't decode HEIC. On the iPhone, switch Settings → Camera → Formats → Most Compatible and new photos are saved as JPG; photos you've already taken are often converted to JPG automatically when shared. In Safari on a Mac or iPhone, HEIC opens on this page too.

I shot it upright but it comes in sideways

Photos carry a hidden note saying "rotate me 90° for viewing", and some programs honour it while others ignore it — PDF viewers don't read it at all. When this tool finds a photo with that rotation flag, it bakes the rotation in and re-saves the image, so it displays upright in every viewer. The one side effect: that photo has to be re-encoded as JPEG, so it alone is recompressed.

The pages in my PDF are all different sizes

Paper size is set to Match image size, so pages follow each photo's resolution. Pick A4 or Letter and every page comes out identical.

Are my files uploaded anywhere?

No. Reading the images and building the PDF happens entirely inside your browser — it works exactly the same with the internet disconnected. That matters here, because this tool routinely handles IDs, bank details and contracts. Your files aren't kept in browser storage either, so close the tab and nothing remains. The flip side: reload the page and you start from scratch.

The download is always called images.pdf

That's deliberate. Some browsers mangle or discard download names containing non-ASCII characters, so the file uses one fixed, safe name — just rename it after downloading. If it's headed for a submission portal, you'd likely be renaming it to their required name anyway.
