Convert JFIF to PDF online without losing quality
A .jfif file is a JPEG with a different extension. Some browsers save web images this way, and many apps, upload forms and email clients then refuse to open them.
Turning the picture into a PDF solves that. A PDF opens on every device and is accepted almost everywhere you need to send it.
How to convert JFIF to PDF
- Add your .jfif files or drop them on the page.
- Arrange the order and choose the page size and merge option.
- Convert and download your PDF.
What is a JFIF file?
JFIF stands for JPEG File Interchange Format. It is the standard container for JPEG images, the same format behind most .jpg files. Only the extension is different, which is why your photo viewer opens it while many websites refuse it.
Why does my browser save images as .jfif?
On Windows, a registry setting can map the JPEG type to the .jfif extension, so Chrome and Edge sometimes save JPEG images with that ending. Nothing is wrong with the image. The file just has a name some software does not expect.
Does converting JFIF to PDF reduce quality?
Not with the default settings. Images are stored in the PDF losslessly, so the picture is not re-compressed on the way in.
If you need a smaller file, switch on Compress images and choose a quality level. Leave it off when the picture matters more than the file size.
How do I put several JFIF files into one PDF?
Add all your files, drag them into the order you want and switch on Merge all images into one PDF. With merge off, each image becomes its own PDF, which helps when every picture goes to a different place.
Page size, orientation and margins
Keep each page the same size as its image, or choose A4, Letter, Legal, Tabloid, Executive, A3, A5 or B5. Orientation can be portrait, landscape or automatic.
The image can fit inside the page, fill it or stretch to it, and you can add a page margin. You can also rotate any image before converting.
What if one of the files is damaged?
Skip images that cannot be read is switched on by default. One broken file does not stop the rest of the batch from converting.
Should I just rename .jfif to .jpg?
Often that works, because the data inside is already JPEG. Renaming does not help when a form accepts only PDF, when you need several pictures in a single document, or when you want fixed page sizes for printing. In those cases converting is the better fix.
What you get
- JFIF images stored in the PDF losslessly by default
- Optional compression with a quality level you choose
- One merged PDF, or a separate PDF for each image
- Pages sized to the image, or standard paper sizes from A5 to A3
- Rotation, margins and fit options before you convert
- Damaged images skipped so the rest still convert

Need the picture as an image file instead? JFIF to PNG and JFIF to JPG convert it directly. If the finished PDF is heavier than you need, Compress PDF will trim it.
