Choose photos or scans, put them in the order you want, and download one PDF. Pages can be A4 with a margin of your choosing or exactly the size of each image. Everything happens in this page: the files are never uploaded, which is the difference that matters when the images are an ID document, a contract or a medical report.
JPG, PNG or WebP. Add as many as you need — each becomes one page.
Add images to build the PDF.
Images are read and the PDF is assembled in this page — nothing is uploaded. The JPEG data goes straight into the PDF, so the file is about as large as the images you added.
How it works
PDF has a filter called DCTDecode, and DCTDecode is JPEG. That means a JPEG can be dropped into a PDF as-is, with the file describing where to place it on the page. This tool does exactly that — it writes the PDF structure around your images without re-compressing them a second time, so the result is roughly the size of the pictures that went in and there is no extra quality loss.
Anything the browser can decode is accepted, including PNG and WebP, and those are converted to JPEG first because that is the format a PDF can carry directly. Transparent areas are filled with white rather than turning black, and the image is drawn as the browser displays it, which also settles any EXIF rotation.
On A4 pages the page follows the orientation of each image, so a portrait photo gets a portrait page and a landscape one gets a landscape page, and the image is scaled to fit the margins and centred. Choose the original-size option instead and each page is exactly the pixel dimensions of its image at 72 dpi — the right choice when the images are already page-shaped scans and you do not want any white border.
Practical examples
A passport or ID copy
Photograph both sides, add them in order and export a two-page A4 PDF. Nothing is uploaded, which is the whole point when the document identifies you.
Phone photos of a signed contract
Six pages photographed on a desk become a six-page PDF at A4 with an 18 pt margin, in the order you arranged them with the arrows.
Receipts for an expense claim
Small receipt photos on A4 with no margin fill the page, which makes them easier to read on screen than a thumbnail in an email.
A scanned form that is already page-shaped
Choose the original-size option and the PDF page matches the scan exactly — no border, no scaling, no second guess about what got cropped.
Frequently asked questions
Are my images uploaded to a server?
No. The conversion runs in your browser using its own image decoder, and the PDF is assembled locally. That is worth checking on any converter you use for documents — most popular ones upload the file, process it on a server and email you a link.
Does converting reduce image quality?
JPEG input is embedded without re-compression only after the browser normalises it, which involves one re-encode at high quality (92%). PNG and WebP are encoded to JPEG once. In practice the difference is invisible at document scale; if you need pixel-exact archival copies, keep the originals too.
What formats can I add?
JPEG, PNG and WebP — anything the browser can decode. HEIC photos from an iPhone usually need converting first, since most desktop browsers cannot decode them.
How do I change the page order?
Use the up and down arrows next to each image. The order in the list is the order of pages in the PDF, top to bottom.
Should I choose A4 or original size?
A4 for anything that will be printed or emailed to an office — everyone can print it without scaling surprises. Original size when the images are already the right shape and you want no white border at all.
What does the margin do?
It keeps a border of empty space around the image on A4 pages. 18 pt is about 6 mm and stays clear of most printers’ unprintable edge; zero fills the page completely.
Is there a limit on how many images I can add?
No fixed limit, but everything is held in memory, so a few dozen phone photos is comfortable while several hundred large images may exhaust a tab. Split very large jobs into two PDFs.
Why is my PDF about the same size as the photos?
Because the images are the PDF — the structure around them is a couple of kilobytes. If the result is too large for an email, compress the images first and then convert.
Can it make a PDF where the text is searchable?
No. The pages are pictures, so there is no text layer. Making a photo searchable needs OCR, which is a different kind of tool entirely.
Will the PDF open everywhere?
Yes — it is a standard PDF 1.4 file with a normal cross-reference table, which every reader from Acrobat to a phone’s built-in viewer handles.
Can I convert a PDF back to images?
Not with this tool; it only goes one way. Extracting pages as images needs PDF rendering, which is a separate job.
Does it work offline?
After the page has loaded, yes. There are no network requests during conversion, so you can even disconnect first and watch it still work.
