Images to PDF
Combine JPG or PNG images into a single PDF, in the order you choose. The pictures never leave your device.
Processed on your device — no upload
How to use it
- Choose the JPG or PNG images you want in the document.
- Put them in order with the arrows, then pick a page size.
- Press create. The finished PDF downloads to your device.
How it works
A PDF page is a canvas with drawing instructions on it, and an image is one of the things it can be told to draw. Building a PDF from pictures means creating a page for each image, embedding the image bytes into the document, and issuing a single instruction to paint it at a given position and size.
JPG and PNG are embedded directly, without being decoded and re-encoded. That matters: your photos go into the PDF at exactly the quality they left your camera or scanner, and the file size of the result is roughly the sum of the inputs. Nothing is recompressed behind your back.
The page size choice is the one that matters. Match each image makes every page exactly the pixel dimensions of its picture — no borders, no letterboxing, and no distortion, which is what you want for screenshots or artwork. Fit onto A4 places each image centred on a standard sheet with a margin, choosing portrait or landscape per image, which is what you want when the document will be printed or filed.
All of this happens inside the browser tab. The images are read from your disk into memory, assembled by JavaScript on your own processor, and handed back as a download. Nothing is transmitted — which for photographs is worth more than it sounds, because images often carry GPS coordinates and device identifiers in their metadata.
A worked example
You photographed four pages of a signed contract with your phone: IMG_4471.jpg through IMG_4474.jpg. The other party wants one PDF, not four photos in an email.
Choose all four at once. They arrive in the order the picker returned them, which for sequential camera filenames is usually correct — but check, because a phone that rolled over from IMG_4499 to IMG_4500 can sort oddly. Use the arrows to fix anything out of place.
Set the page size to Fit onto A4, since this document is going to be printed and signed. Press create, and images.pdf arrives with four A4 pages, each photo centred with a small margin. Phone photos are landscape-shaped when taken sideways, so the tool gives those pages a landscape sheet automatically rather than shrinking the image to fit a portrait one.
A number worth knowing: four 12-megapixel phone photos are typically 3–5 MB each, so the PDF lands around 16 MB. That is large for email. If size matters more than fidelity, reduce the images before building the PDF — the tool embeds what you give it rather than silently degrading it.
Going the other way — a PDF you want as pictures rather than pictures you want as a PDF — is the PDF to images tool.
Questions
How do I convert JPG to PDF?
Choose your JPG files and each becomes a page, in the order shown. PNG to PDF works identically, and the two can be mixed in one document.
Which image formats can I use?
JPG and PNG. These are the two formats the PDF specification supports embedding directly, which is why they go in without any quality loss. HEIC from an iPhone, WebP and AVIF are not supported — convert those to JPG or PNG first.
Are my photos uploaded anywhere?
No. The document is assembled in your browser on your own device. There is no backend to this site, so nothing is transmitted. That matters more for photos than for most files, because images frequently carry GPS location and camera serial numbers in their metadata.
Which page size should I choose?
Choose "match each image" for screenshots, artwork or anything that will only be viewed on screen — it avoids borders and never distorts the picture. Choose "fit onto A4" when the document will be printed, filed or sent somewhere that expects standard paper.
Will the images lose quality?
No. JPG and PNG data is embedded as-is rather than decoded and re-encoded, so the pictures in the PDF are pixel-identical to the files you selected.
How do I change the order of the pages?
The list order is the page order. Use the up and down arrows to move an image, or the ✕ to drop one. The file picker usually returns images alphabetically, which is not always the order you took them in.
Why is my PDF so large?
Because the images are embedded at full quality. A modern phone photo is several megabytes, so a handful of them makes a file of tens of megabytes. Shrink the images first if you need a smaller result.
Does the PDF keep the photo metadata?
The embedded image data is carried over as it was. If you are concerned about location data travelling with the document, strip it from the images before building the PDF, and run the result through the metadata tool afterwards.
Is there a limit on how many images I can add?
No fixed limit. The practical ceiling is your device memory, since every image is held in RAM while the document is built. Dozens of photos are fine on a laptop; a phone will struggle sooner.
Which picture formats can go in?
JPG, JPEG and PNG. Image to PDF, JPEG to PDF and picture to PDF all describe the same job, and you can mix formats in one document — some pages from photographs, others from PNG screenshots.
Can I turn photos or pictures into one PDF?
Yes — photos to PDF and pictures to PDF describe this exactly. Drop in as many images as you like, put them in order, and they become images to PDF files in a single document, one picture per page.
