Photos are for looking at; the places that ask for them usually want one document.
Scanned documents and receipts
A flatbed scanner and most phone scanning apps save a JPEG per sheet, so a ten-page lease,
a stack of receipts or a signed contract arrives as ten separate files. A PDF puts them
back into a document: pages in order, nothing to rename, and a single file that still reads
properly when it is forwarded to an accountant or a landlord.
Homework, forms and portals that allow one file
School portals, job applications and insurance claims routinely accept exactly one upload
and cap its size. Six photographs of a form, a drawing and a page of workings will not fit
that model; one PDF will. It is also the format a teacher or an office worker can annotate
and print without installing anything.
Sending several photos as one file
A buyer asking for more pictures of an item, a client reviewing progress on a site, a
family member who wants the holiday shots in one go: a PDF keeps the pictures in the order
you decided and cannot be reshuffled by the mail client or the messaging app on the way.
One attachment, one download, the same sequence on the other end.
How the pages get their order
Order is the one thing a PDF cannot repair later, so the list in front of you is the document.
First in the list, first page
Add the title page, the receipt or the front of the form first and it becomes page 1. Each
row shows what it is — a thumbnail for a photo, the name and the size — so the list can be
read as the finished sequence before you convert anything.
Arrows, not dragging
Use the ↑ and ↓ buttons at the end of a row to move it one
place, and × to take it out. Rows cannot be dragged: a drag over the page
is read as "add these files" and appends them, which would silently reorder the document.
The buttons are deliberate, work with a keyboard and behave the same on a phone.
Batches append, they do not replace
Drop ten photos, then drag in five more from another folder: the second batch lands after
the first, keeping its own order. Add more does the same from the picker,
and pasted screenshots join at the end. The list stops at 30 images, which is where the
intake starts refusing.
Page size, orientation and margin
Pick paper for something that will be printed, a fit-to-image page for something that will be
placed inside another document.
A4
210 × 297 mm and the default, because it is what offices, portals and print shops expect.
A photo is scaled down until it fits, keeps its proportions and is centred, so a portrait
shot of a receipt lands in the middle of a portrait page with a clean border.
US Letter
216 × 279 mm, the paper used in the United States and Canada. Same layout as A4: the photo
is fitted inside the printable area, centred, never cropped. Choose it when the PDF is
going to be printed on that side of the Atlantic.
Fit to image
The page is the photo. No paper, no white bands — useful for a picture that has to keep its
exact proportions, such as a plan or a wide panorama, and for a page that will be pasted
into another layout. Set the margin to 0 to remove the border as well.
Orientation and the margin field
Automatic turns each page to follow its photo: a landscape shot of a garden gets a
landscape page, the portrait receipt after it stays portrait, in the same PDF. Portrait or
landscape forces one shape throughout. The margin is in millimetres and defaults to 10 mm
on A4 and Letter — the border most printers need — and 0 is allowed.
The limits, and what happens to the JPEG
Enough room for a full document, with a cap that keeps one request from hogging the server.
30 images, 25 MB each, 100 MB in total
That is roughly thirty 12 megapixel phone photos, or a scanned document of thirty sheets.
The check runs while you add files: one over 25 MB is named and skipped while the rest stay
in the list, and going past 30 images or 100 MB together stops the intake with a message
saying which limit was reached.
No upscaling
A 1200 px photo stays 1200 px wide — nothing is resampled to a larger size and no soft
pixels are invented. On an A4 or Letter page a small picture is drawn at up to 1.5× its
natural size so it does not look abandoned in the middle of the sheet, and past that it is
left alone.
Capped at 4000 px on the longest side
A 48 megapixel photo is scaled down to at most 4000 px before it goes in. Across the
printable width of an A4 page that is still over 500 dpi, so the print is sharp, while the
PDF stays a size that can be mailed instead of one that has to be sent through a file
transfer service.
Upright pages, one encode
Phones often record a photo sideways and store a rotation flag instead of turning the
pixels; that flag is applied, so the page arrives the right way up with the width and
height to match. The photo is then written into the PDF once, at high quality — there is no
visible difference at that setting, only a file that is far smaller than the sum of the
originals.
How to convert JPG to PDF
Three steps, no account and nothing to install.
Add the JPGs
Drop them onto the box, click it to browse, or paste with Ctrl+V (Cmd+V on a Mac). A .jpeg
named the long way works just as well. Add the first page first — the list is the document
— and every file is checked against the limits as it lands.
Fix the order and pick the paper
Move rows with ↑ and ↓, remove one with
×, then choose A4, US Letter or fit to image. Leave orientation on
automatic unless the whole document has to share one shape, and set the margin in
millimetres — 10 mm is the default, 0 fills the sheet.
Create and download the PDF
The result card shows the page count, the combined input size and the finished PDF, so an
unexpectedly heavy file is visible before you save it. One click downloads the document,
ready for an email, a portal or a printer.
Three tips for a cleaner PDF
A minute of care before the upload saves a re-scan afterwards.
Shoot documents straight and evenly lit
Lay the sheet on a dark, flat surface, hold the phone parallel to it and let the light come
from the side instead of from behind you. The converter cannot straighten perspective or
lift a shadow — it places the photo you give it — so the page is only as readable as the
shot.
Compress the heavy ones first
A camera JPEG can exceed the 25 MB per-image limit, and a document of thirty of them is
slow to send. Run the big files through the JPG compressor
before adding them: quality 70–80 is invisible on a document page and usually halves the
weight.
Start from the right format
Photos taken on an iPhone may be HEIC rather than JPG — HEIC to
PDF takes them straight in, and HEIC to JPG turns them into
a JPEG first if some other tool insists. Screenshots and diagrams belong on the
PNG to PDF page, where transparency and thin lines survive.
Frequently asked questions
Is this JPG to PDF converter free?
Yes. There is no account, no payment, no watermark on the document and no limit on how many PDFs you build. Only a short rate limit applies, so one visitor cannot keep the server busy for everyone else.
How many photos can go into one PDF?
Up to 30 images, at most 25 MB each and 100 MB together for the whole request. The list is checked as you build it: a file that is too large is named and skipped while the others stay, and reaching 30 images or 100 MB stops the intake with a message naming the limit. Everything is held in memory, which is why the numbers are what they are.
Will the photos lose quality in the PDF?
Very little, and never on purpose. Nothing is upscaled, so a photo keeps the pixels it had, and a picture longer than 4000 px on its longest side is scaled down to that — still well over 500 dpi across an A4 page. Each photo is written into the PDF once at high quality, and the original file on your disk is untouched.
Is the text in the PDF searchable?
No. Each page is the photo you supplied placed on a page, so the PDF contains images and no text layer: a scanned receipt or a photographed form cannot be selected with the cursor, copied out or found with the search box. Recognising the words would need optical character recognition, and this converter does not do that.
What happens to my files?
Files are processed on our server and not stored. The JPEGs are decoded, laid out as pages and returned as one PDF; no account is involved and the download is the only copy that leaves the conversion.
