Private target-size image compression
Compress images to your chosen size limit.
Set a maximum file size, then create a new JPEG, PNG, or WebP at or below that target. HEIC and HEIF inputs use JPEG unless you choose another output.
Target size stays private too

Compression flow
A bounded search, followed by verification
For JPEG and WebP, MetaRinse searches a limited number of quality levels. It reduces resolution only when the lowest allowed quality is still too large and you explicitly permit resizing. PNG uses no quality slider: only optional resolution reduction can lower its encoded size.
Search quality and size
JPEG and WebP try quality first, then resize only with permission. PNG can use resolution reduction only.
Verify the output
MetaRinse checks the real byte size, format, dimensions, and removable metadata before enabling download.
Local by design
Images and targets never leave your device.
Every image, filename, preview, target size, and result stays inside this browser. MetaRinse does not send image-related data to a server or external service.
Honest result status
The target is a maximum, not an exact size
Encoding size varies by image content and browser. MetaRinse offers a result only when the generated file is at or below the selected target and its removable metadata check passes. Otherwise it reports that the target could not be reached.
