Short answer
Start with moderate compression, inspect the image at its final display size, and only push quality lower when upload limits or page speed targets require it.
Image Compression Quality Settings: A Practical Guide
Start with moderate compression, inspect the image at its final display size, and only push quality lower when upload limits or page speed targets require it.
Why it matters
- Use lighter compression for screenshots and documents
- Check faces, text, gradients, and product edges after export
- Keep one source copy before creating delivery versions
What to know
Compression should be judged in the context where the image will actually be used, not only by file size.
Photos tolerate more lossy compression than screenshots, text-heavy images, and product UI captures.
A saved original gives you room to re-export if a CMS, marketplace, or client asks for a different size.
