Frequently asked questions
How do I reduce JPEG file size?
Add the images, then choose a quality level or a target size in KB. Each file is re-encoded as JPEG at the best quality that fits.
Will the image look different?
At moderate settings the difference is hard to see. Lower quality or a very small KB target makes compression artefacts more visible.
Are my files uploaded?
No. Compression runs in your browser.
