Common questions

What is a JFIF file?

JFIF stands for JPEG File Interchange Format. It is the small wrapper that most JPEG pictures are stored in. A file ending in .jfif holds a normal JPEG picture, and any program that opens JPEG can open it once the name is changed to .jpg.

Why did Windows save my picture as .jfif?

Some Windows setups link the .jfif name to JPEG pictures, so a picture saved from a browser or an email can arrive as .jfif instead of .jpg. The picture inside is the same either way. Only the name differs, and this page ignores the name.

Can I just rename a .jfif file to .jpg?

Yes. Renaming a .jfif to .jpg works because the contents are already a JPEG. It is only needed when a site or app refuses the .jfif name. Here you do not need to rename anything, because the file is checked by its contents.

Does converting JFIF to PDF lose quality?

No. The JPEG inside your .jfif is placed in the PDF as it is, without being compressed again, so it looks the same. Only the page around it is new. Your original .jfif file is not changed in any way.

Can I put several JFIF files in one PDF?

Yes. Add as many pictures as you like and put them in order. Each one becomes its own page. You can mix .jfif files with JPG, PNG, WebP and other pictures in the same PDF.

Is my file uploaded when I use JFIF to PDF?

No. Your pictures are read and placed into the PDF in your browser. The file is not sent to our servers.

Is JFIF to PDF free, and are there limits?

You can use it free. You get 2 free uses in total, no account needed. Free files can be up to 50 MB. Pro has no limit on uses and allows files up to 500 MB. We check the limits before a use starts, so a finished file is never held back.

Can I use JFIF to PDF on a Windows PC?

Yes. Open this page in Chrome or Edge on your PC, add your file and download the result. Nothing to install, and your file stays on your device.

How do I convert JFIF to PDF?

Add your pictures to JFIF to PDF, drag them into the order you want, choose a page size and download one PDF. Each picture becomes a page. The files are read in your browser and are not sent to our servers, and you do not need to rename them first.

What is the difference between JFIF and JPG?

There is no difference in the picture. JFIF is the container format most JPEG files use, and .jfif is simply a different name for the same kind of file. A .jfif opens wherever a .jpg opens, once it is renamed. Only some older programs look at the name and refuse .jfif.

Why won't my computer open a .jfif file?

Some programs only know the .jpg and .jpeg names and have no app set for .jfif. The picture inside is fine. Rename the file to .jpg, or skip the problem by adding it to JFIF to PDF, which reads the contents and makes a PDF that opens everywhere.

How do I stop Windows saving pictures as .jfif?

Pictures saved from a browser take the name that Windows links to JPEG, and on some PCs that is .jfif. Saving through another browser or choosing the .jpg name in the save box often avoids it. Pictures you already have can be turned into a PDF with this page.

Is it safe to convert JFIF to PDF online?

With JFIF to PDF, your pictures are read and placed into the PDF inside your browser and are not sent to our servers. That makes it a good fit for photos of IDs, receipts, signed pages and other private papers. You can check this in your browser's network tab.

Can I convert JFIF to PDF for free?

Yes. You get 2 free uses in total with no account, and one conversion counts as one use. Free files can be up to 50 MB each. Pro has no limit on uses and allows files up to 500 MB. The limit is checked before the conversion starts.

Can I mix JFIF and JPG files in one PDF?

Yes. Add .jfif, .jpg, .jpeg, PNG and other pictures in any order, and each becomes one page. The page tells the type by the contents, so the names do not matter. A mixed set is handy when some pictures came from a phone and others were saved on a PC.

Does JFIF to PDF work on a phone?

Yes. Open JFIF to PDF in your phone's browser, choose the pictures from your files or camera roll, and download the PDF. It all runs on the phone, so nothing is uploaded. Take a photo also opens the camera for a new picture.

How do I make a JFIF to PDF file smaller?

Run the finished PDF through Compress PDF, which shrinks photo-heavy files the most. Fewer or smaller pictures also give a smaller PDF. Compressing makes a new copy, so your first PDF stays as it was, and your pictures never leave your device.

Can I turn a JFIF into a PNG or JPG instead?

This page makes PDFs. To get a JPG, rename the .jfif to .jpg, since the contents are already a JPEG. To get a PNG, make the PDF here and then use PDF to PNG. Each step runs in your browser and your pictures stay on your device.
