A .jfif file is a JPEG — put it into a PDF without re-compressing it.
On your device. No watermark. No sign-up.
This tool is processed locally with JavaScript inside your browser tab. The document is not uploaded, stored or seen by a server, which makes it suitable for contracts, invoices, CVs and medical or financial records.
JFIF stands for JPEG File Interchange Format. It is the standard wrapper that declares “this file is a JPEG”, and the picture inside it is an ordinary baseline JPEG.
The same bytes are handed to you as .jpg on most websites and as .jfif when a CDN, Windows Photos or an older Android gallery writes the file. Converting JFIF to PDF is therefore not a picture conversion at all: the JPEG stream goes into the PDF and only the container around it changes.
The JPEG is embedded as it is, with no decode and no re-encode. The picture inside the PDF is bit-for-bit the picture you added.
This matters because re-saving a JPEG as a JPEG is what causes visible damage, and doing it a few times leaves a soft, blocky image. This tool never does that. The PDF is about as heavy as the JFIF files added together.
Some sites serve images with the MIME type image/jfif and name the file .jfif. Windows Photos, some Android galleries and older editors do the same, and so do a few scanners and cameras.
If a form or an upload box rejects .jfif, the file is still a normal JPEG. Renaming it to .jpg works in most places, and converting it to a PDF here works everywhere a PDF is accepted.
JPEG is the compression. JFIF and EXIF are two ways of wrapping a JPEG with a small block of information at the start of the file. JFIF is the older, simpler wrapper; EXIF is what cameras write, and it can hold the date, the camera model and the GPS location.
Because the file goes in untouched, that block goes in with it. If the JPEG carries GPS coordinates, they are inside the PDF. To leave them behind, re-save the picture as a new JPG first — Resize Image to KB redraws the pixels and drops the old metadata — and convert that file instead.
Fit to each image makes every page exactly as large as its picture, one pixel to one point. A4 and Letter give every page the same size, with the image scaled to fit and centred and never stretched.
Set the order with the arrows; one image per page; one PDF per run. For printing, choose A4. For a quick look on screen, Fit to each image is fine.
The PDF is built inside this browser tab. Your files are read from your disk and never sent to a server, so it is safe for ID photos, certificates and scanned documents. After your first visit the tool also works offline.
Yes. There is no account, no daily limit and no watermark on the PDF.
No. The PDF is built in your browser and the files never leave your device.
Yes, in practice. Both hold a JPEG picture; JFIF is the name of the container format that .jpg files normally use. Renaming .jfif to .jpg usually works.
No. The JPEG is embedded as it is, without being decoded or re-encoded, so the picture is unchanged.
Yes. Add them all, set the order with the arrows, and press Convert. Each image becomes one page.
Both wrap a JPEG with a small block of information. JFIF declares the file is a JPEG and gives its basic geometry; EXIF carries camera details such as date, model and GPS location.
If the original JPEG had GPS in its EXIF block, yes — the file goes in untouched. Re-save the picture as a new JPG first (Resize Image to KB drops the old metadata) if you want it gone.
Most galleries open them because the content is a JPEG, but some apps go by the extension. Convert the file to PDF here, or rename it to .jpg.
A4 for printing, portals and merging with other documents. Fit to each image keeps each photo at its own proportions for reading on screen.
PDF to JPG gives you .jpeg files, which are JPEGs. Rename one to .jfif if a form insists on that extension.
Yes. Pick the files from your gallery or Files app; large photos can take a few seconds on an older phone.
