FAQ
Reducing image size questions
Can I reduce image size without making it blurry?
Yes. Preview the image while changing quality, dimensions, and format so you can stop before compression becomes visually distracting.
What reduces image size the most?
Resizing oversized dimensions usually has the biggest effect, followed by choosing a better web format and tuning quality.
Is WebP best for reducing image file size?
Often, yes. WebP can produce smaller web images, but JPEG or PNG may still be better depending on the image and transparency needs.
Are images uploaded while optimizing?
No. Image Truth runs the optimization workflow locally in your browser.
