What is JPEG (JPG)?
JPEG is the most widely used photo format, trading some detail for very small files.
JPEG compresses smooth color gradients extremely well, which is why almost every camera saves photos this way. Sharp edges, such as screenshots with text, show visible artifacts at low quality.

Frequently asked questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device, and there is no upload.
Is there a file size limit?
There is no limit on our side, but your browser memory is. Images work for very large files; for videos, files above a few hundred megabytes can fail on devices with little memory.
Will the quality suffer?
That depends on the target format and settings. Use the quality option to balance size and detail; lossless targets keep everything the source contained.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. Fast hardware paths are used where available, with a compatible fallback otherwise.
