FAQ
- Will compression ruin quality?
- Lower quality means smaller files and more artifacts. Start high and lower until the size fits your limit.
- Is PNG lossless?
- PNG compression here targets smaller delivery size; for photos, JPG/WebP often shrinks more effectively.
- Are my images uploaded?
- No. Compression uses local browser APIs only.
- Can I hit a exact KB target?
- You can aim with quality and max size controls. Exact byte targets depend on the image content.
- Does it work offline after load?
- Once the page is loaded, processing does not need a server round-trip for your file.
