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 and .jpeg are the same JPEG format; JPG to JPEG changes the label by default and keeps the bytes.
Tick Re-encode to re-compress at a quality; otherwise the original bytes are preserved.
The result panel says whether bytes were preserved or the image was re-encoded.
In-browser only; nothing is uploaded.
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.
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.
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.
No. JPG to JPEG renames (or optionally re-encodes) the file in your browser, and it is never sent to imgtoolsbase or any server.
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.
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.
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.
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.
