Compress an image as WebP or JPEG with an adjustable browser-local quality setting.
Re-encode a JPEG, PNG, or WebP image as WebP or JPEG with adjustable quality while keeping its current pixel dimensions.
Re-encode an image at a chosen quality to compare output size with the original. The tool reports whether the result is smaller, the same size, or larger instead of promising compression will always help.
The selected image is decoded and processed in the browser. Keep the original until the downloaded output has been opened and checked on the target device.
Last reviewed for accuracy:
Scenario: A 3 MB JPEG photo is re-encoded as JPEG at a moderate quality setting.
Result: The browser reports the generated size and percentage difference before download.
Lossy encoding discards some visual information and may reduce bytes, but an already optimized source can produce little savings or even a larger file.
The image is decoded to pixels and encoded again through the browser's supported codec. Quality settings are codec hints rather than a universal percentage of original quality or size.
No. A source that is already highly compressed can occasionally produce a larger result, so Fieldlet shows the actual generated size before download.
The original may already be efficiently encoded, or the selected format and quality may require more bytes. The result comparison tells you when keeping the original is better.
