Add your images

Drop your .jpg or .jpeg files into the box above.

Step 2

Pick the extension you need

Choose .jpeg or .jpg — whichever the form is demanding.

Step 3

Convert and download

One file downloads directly; several arrive as a single ZIP.

Built for private image conversion

Private by design

Conversion runs entirely in your browser — files are never uploaded.

Batch with ZIP

Convert one file or dozens; multiple outputs download together as a ZIP.

Portal-ready output

JPG and JPEG are the same format

Here is the part nobody explains when your form gets rejected: .jpg and .jpeg are identical. The format is JPEG; the three-letter .jpg extension exists only because early Windows versions limited extensions to three characters. Both files contain exactly the same kind of data.

So why does the portal reject one?

Because many upload validators check the filename extension as plain text rather than inspecting the file itself. If the form’s rule says “accepts .jpeg” and your file ends in .jpg, it is refused — even though the file is perfectly valid. It is a paperwork problem, not an image problem.

What this tool actually does

It renames the extension and re-encodes the image cleanly, which matters more than it sounds: some strict validators also inspect the file header, and files exported by phones or editors occasionally carry metadata that trips them up. A clean re-encode with the correct extension satisfies both the filename check and the header check.

Private by architecture

Everything happens in your browser. Zero bytes are uploaded — which matters, because the documents people are forced to re-extension are usually ID photos and certificates.

Frequently asked questions

Is there any difference between JPG and JPEG?
No — they are the same image format. The .jpg extension exists only because older Windows systems allowed just three characters. The file contents are identical.
Why does the upload form reject my .jpg file then?
Many portals check the filename extension as text rather than examining the file. If their rule expects .jpeg and your file ends in .jpg, it's refused despite being a valid image. This tool fixes that.
Can I just rename the file myself?
Often that works, but not always — some validators also inspect the file header or reject unusual metadata from phone cameras. This tool re-encodes the image cleanly with the right extension, which passes both checks.
Can I convert JPEG back to JPG?
Yes — pick .jpg from the extension menu. The tool works in both directions.
Does this reduce image quality?
The image is re-encoded at high quality, so any change is imperceptible in normal viewing. If a portal also enforces a KB limit, use our Compress Image tool afterwards.
Can I convert several files at once?
Yes. Add as many as you like — they convert together and download as a single ZIP, free and without limits.
