How to use the image to PDF converter
Add your pictures and download the PDF: each picture becomes a page of A4, in the order of the list. JPGs go in without recompression. Change the paper size or its direction if you need to, or set a size limit in KB or MB if a form asks for one.
- Add your imagesUp to 20. Each one becomes a page, in the order of the list.
- Choose the paper and the qualityA4 by default. Keep the original quality, or set a size limit.
- Download the PDFOne file, made on your device.
About this tool
A PDF is how a photo becomes a document: a scanned certificate for a form, pages of notes photographed with a phone, receipts for an expense claim, a set of pictures to print. Add the pictures and each becomes a page. The list above the preview sets the order; the arrows on each picture move it, and more can be added at any time.
A PDF can hold a JPEG exactly as it is, and this page uses that. With "Original quality" selected, each JPG is copied into the PDF without being decoded and encoded again, so the page is the photo you added, down to the pixel. Only its EXIF block is left behind, which is where a camera records the time and often the place. PNG, WebP and other formats are stored as high-quality JPEGs, because that is what a page here holds.
When the file has to be small, choose "Smaller file" to set a quality and a maximum picture size yourself, or "Size limit" to name a size in KB or MB and let the page find the best quality that fits. The paper size, its direction and the margin are yours to set; by default each sheet is A4 and turns to suit its picture.
What you get
- One picture to a page, up to 20 pages
- JPGs copied in with no recompression
- A4, Letter, Legal, A5, A3, or pages shaped like the pictures
- Reorder with the arrows; add or remove at any time
- Optional size limit in KB or MB
- EXIF data left out, and nothing is uploaded
When to use the image to PDF converter
Documents for an online form
A certificate or an ID photographed with a phone becomes the PDF that an application portal asks for.
Notes and homework
Photographed pages of handwritten work, put in order and sent as one file instead of a string of pictures.
Receipts and bills
A month of receipts gathered into one PDF for an expense claim or for the accountant.
Photos to print or share
A set of pictures sent as one file that opens the same on any computer or phone and prints one to a sheet.
Which quality setting to use
| Setting | What happens to each picture | Size of the PDF | Use it when |
|---|---|---|---|
| Original quality | JPGs copied unchanged; other formats saved as JPG at quality 92 | About the size of your files added together | Quality matters and size does not |
| Smaller file | Saved as JPG at the quality and the maximum size you set | Smaller, by as much as you ask for | Emailing or storing many pages |
| Size limit | Quality, then pixel size, lowered until the file fits | At or just under the limit | A form or a portal sets a maximum |
| Page size: same shape as each picture | Nothing: this changes the page, not the picture | Unaffected | Photos, slides and artwork with no white margin |
How it works
The PDF is written directly by this page, object by object: a catalogue, a list of pages, and for each page an image, a one-line drawing instruction and the page itself, followed by the table that tells a reader where each object starts. A PDF stores photographs with the same compression a JPG uses, so a JPG's compressed data can be placed in the file as it stands. That is what happens in "Original quality": the data is copied, the EXIF block, comments and any extra data after the picture are dropped, and a colour profile, if the photo carried one, is attached to the image so that its colours are read the same way.
A phone often stores a photo sideways and records the turn in its EXIF data. A PDF reader ignores that record, so the turn is written into the page's drawing instruction instead: the picture appears upright and its data is still untouched. On paper sizes, a picture is fitted inside the margins, centred, and drawn no larger than one point per pixel, which is 72 dots per inch. In the size-limit mode, the room left after the PDF's own structure is shared between the pictures by pixel count, and each is encoded at the highest quality that fits its share, with its pixel size reduced only when quality alone cannot get there. A kilobyte is counted as 1000 bytes.
Common problems and how to fix them
- The PDF is much larger than I expected
- In "Original quality" the PDF is about as big as the pictures you added, and phone photos are several megabytes each. Choose "Smaller file", or "Size limit" if you have a number to meet.
- A picture is the wrong way round
- Pictures are shown the way your phone's gallery shows them. If one really is sideways, turn it first with the Image Rotator and add the turned copy.
- Text in the PDF cannot be selected or searched
- The PDF holds pictures of pages, not text. Nothing here reads the writing in a photo. Selectable text needs a program with text recognition (OCR), which this site does not have.
- A transparent PNG has a white background in the PDF
- A page here holds a JPEG, which has no transparency, so transparent areas are painted white. On white paper that is what you would see anyway.
- A HEIC photo from an iPhone was skipped
- Most browsers cannot open HEIC files. Share the photo from the phone in its "Most Compatible" (JPG) form, then add it.
Frequently asked questions
Does converting to PDF reduce the quality of my photos?
Not for JPGs in "Original quality": the JPEG data is placed in the PDF unchanged, so there is nothing to lose. Other formats are converted to JPEG at quality 92, which is hard to tell from the original. Quality is reduced only if you choose "Smaller file" or "Size limit", and then by as much as the setting requires.
How do I change the order of the pages?
Use the two arrows on each picture in the list above the preview. The numbers on the pictures are the page numbers.
Can I put more than one picture on a page?
Not here: each picture gets its own page. To put several on one page, combine them first with Join Images or the Collage Maker, then add the combined picture.
Why is my small picture not filling the page?
A picture is scaled down to fit the page but never enlarged past 72 dots per inch, because blowing up a small picture only makes it blurry. A 600 pixel wide image is therefore drawn about 21 cm wide at most. Choose "Same shape as each picture" as the page size if you want the picture to cover the whole page.
Is there a limit on the number of pages?
20 pictures, so 20 pages. For a longer document, make two PDFs and join them in a PDF program; this site cannot merge PDFs.
Are my pictures uploaded to make the PDF?
No. The PDF is assembled by your browser on your own device, and the pictures are not sent to a server. The file also carries no author name, creation date or program name.
Can I add a password, page numbers or a header?
No. The PDF contains your pictures on blank pages and nothing else.
