JPG to JPEG
Switch between .jpg and .jpeg (the same JPEG format) without re-compressing by default — your bytes and metadata are kept. Optional re-encode available.
JPG to JPEG is a browser-based image tool on ImgToolsBase. Switch between .jpg and .jpeg (the same JPEG format) without re-compressing by default — your bytes and metadata are kept. Optional re-encode available. To use it, upload or drop your image and view the result directly in your browser — no signup and nothing to install.
How this tool works
Rename, not convert
.jpg and .jpeg are the same JPEG format; JPG to JPEG changes the label by default and keeps the bytes.
Re-encode option
Tick Re-encode to re-compress at a quality; otherwise the original bytes are preserved.
Result details
The result panel says whether bytes were preserved or the image was re-encoded.
Privacy
In-browser only; nothing is uploaded.
JPG to JPEG in your browser
JPG to JPEG changes a file’s extension between .jpg and .jpeg. Both are exactly the same JPEG format — the extension is just a label — so by default JPG to JPEG keeps the original file bytes and only renames it, with no quality loss and metadata preserved.
If you actually want to re-compress the image, tick Re-encode and choose a quality; the result panel then reports that the file was re-encoded and that metadata was removed. Left off (the default), the downloaded file is byte-for-byte identical to your original.
JPG to JPEG runs entirely in your browser; the file is never uploaded to a server.
How to use JPG to JPEG
- Upload your .jpg file into JPG to JPEG.
- In JPG to JPEG, leave Re-encode off to rename only (recommended), or tick it and set a quality to re-compress.
- Click Process to produce the .jpeg file.
- Check JPG to JPEG’s result panel — it states whether the bytes were preserved or the image was re-encoded — then download.
Why use JPG to JPEG
JPG to JPEG keeps the exact JPEG bytes and only changes the extension, so there is no quality loss.
Because the rename does not re-encode, EXIF and other metadata are preserved unless you choose to re-encode.
Tick Re-encode if you specifically want to re-compress at a chosen quality; the result panel reports it.
Everything happens in your browser; the file is never uploaded.
Common uses for JPG to JPEG
Rename .jpg to .jpeg for software or an upload form that insists on one spelling.
Switch the extension without re-compressing, so the image is unchanged.
Turn on Re-encode to also reduce the file size at a chosen quality.
Rename from a phone, tablet, or computer browser with the file staying local.
Frequently asked questions
Are my files uploaded to a server by JPG to JPEG?
No. JPG to JPEG renames (or optionally re-encodes) the file in your browser, and it is never sent to imgtoolsbase or any server.
Is JPG to JPEG just an extension rename?
Yes, by default. .jpg and .jpeg are the same JPEG format, so JPG to JPEG keeps the original bytes and only changes the extension — no quality loss, metadata preserved.
Does JPG to JPEG reduce image quality?
Not by default. JPG to JPEG keeps the exact original JPEG data when renaming; quality is only affected if you tick Re-encode, which re-compresses at the quality you choose.
Will my EXIF/metadata survive in JPG to JPEG?
Yes in JPG to JPEG’s default rename mode, because the bytes are untouched. If you turn on Re-encode, the canvas re-encode removes EXIF and other metadata.
Why do .jpg and .jpeg both exist then?
They are interchangeable extensions for JPEG. Some software or workflows expect one spelling; JPG to JPEG lets you switch the label without altering the image.
