Image to JPEG Converter
Convert any browser-readable image to a proper .jpeg file.
Most tools that produce a JPEG file save it with a .jpg extension by default, but a few older systems, some Windows-specific software, and certain government or academic upload portals are written to expect the full four-letter .jpeg extension instead — and will reject a perfectly valid image simply because of that one-letter difference in the filename. This tool solves that specific mismatch: it decodes whatever image you give it and re-encodes it as a standard JPEG, then saves the result with a .jpeg extension rather than .jpg. The image data produced is identical either way — .jpg and .jpeg are just two spellings of the same format — so this is purely about satisfying a picky filename check, not a different kind of file. Conversion happens entirely in your browser via Canvas; nothing is uploaded anywhere.
How it works
- 1
Drop or select any image — PNG, WebP, BMP, TIFF, or anything your browser can open.
- 2
We decode it and redraw it onto a canvas as a JPEG automatically.
- 3
Download the result — it's saved with a .jpeg extension, for systems that specifically require it.
Frequently asked questions
What's the difference between .jpg and .jpeg?
None, as far as the image data goes — both are the same JPEG format. The split exists because early Windows filesystems limited extensions to three characters, forcing '.jpeg' to be shortened to '.jpg'. Some newer or non-Windows systems still expect the full spelling.
Why would a form require .jpeg specifically?
Some validation scripts check the file extension literally rather than the actual file content, and a few were written expecting exactly four characters. If you hit that wall, this tool gives you the same image under the extension it asks for.
Does converting to JPEG lose quality?
JPEG uses lossy compression, so converting from a lossless format like PNG can reduce quality slightly, especially on images with sharp text or flat colors. For ordinary photos, the difference is usually invisible.
