Why use Change Image Quality?

  • Fine-grained quality slider gives you direct control over the trade-off between size and visual fidelity.
  • Real-time file size estimate helps you hit a specific target without trial and error.
  • Supports both JPEG and WebP output for maximum flexibility.
  • Runs entirely in your browser — no images are uploaded, no account needed.

Common use cases

  • Optimize a hero image for web by finding the lowest quality level that still looks sharp at full size.
  • Reduce a product photo to a specific file size target for an e-commerce platform with upload limits.
  • Experiment with quality levels to understand the size-vs-quality trade-off for a particular image.
  • Re-encode screenshots at lower quality for quick sharing where file size matters more than pixel perfection.

Limitations & things to know

  • PNG input is re-encoded to JPEG or WebP (lossy)
  • Quality below 20% may produce visible artifacts
  • Real-time size estimate may differ slightly from final output

About Change Image Quality

Controlling image quality is key to balancing visual fidelity and file size. Xevon Tools' Change Image Quality tool gives you a direct slider from 1 to 100 that re-encodes JPEG and WebP images at your chosen quality level. A real-time file size estimate updates as you drag, so you can find the exact balance without repeated downloads and checks. For web use, quality 70-85 typically delivers files that are dramatically smaller than the original with no visible loss. Below 50, compression artifacts may become noticeable, which can be acceptable for thumbnails or placeholder images. The tool also accepts PNG input, re-encoding it to JPEG or WebP for size savings. This granular control is what separates it from the Compress Image tool, which automates quality selection. Whether you are optimizing a hero image, preparing product photos for a platform with upload limits, or experimenting with encoding settings, this tool puts the quality decision in your hands. Everything runs in your browser with no uploads, no watermarks, and no account required.

Frequently asked questions

The tool outputs JPEG or WebP depending on your selection. PNG input is re-encoded to one of these lossy formats. If you need lossless output, consider keeping the original PNG.
For photos on the web, quality 70-85 is the sweet spot — files are significantly smaller than quality 100, but the difference is virtually invisible. Below 50 you may start to notice compression artifacts.
The estimate is very close but may differ by a small margin from the actual output because the final encoding step may produce slightly different byte counts. The difference is typically under 5%.
The Compress Image tool automatically picks a quality level to hit a target. This tool gives you manual control over the exact quality number, which is useful when you want to fine-tune the trade-off yourself.
