Use cases
- Reducing image file sizes for faster website load times
- Shrinking a photo library before uploading to cloud storage
- Optimizing product images for an ecommerce platform
- Compressing images before sending via email or Slack

Compress 500 product photos to 80% JPEG quality
Frequently asked questions
How much file size reduction can I expect?
Typical JPEG compression at 80% quality achieves 60–80% file size reduction with no visible quality difference. WebP compression is even more efficient — often 30% smaller than equivalent JPEG at the same perceived quality.
What quality setting should I use?
For web use, 75–85% is the sweet spot. Below 60% artifacts become visible. For print or archival, use 90%+. WebP can achieve web-quality results at 70–80%.
Does compressing PNG files reduce quality?
PNG compression in PixelForge is lossless — it only removes unnecessary metadata and optimizes the file structure. If you want lossy PNG compression, convert to WebP or JPEG first.
Can I compress and convert at the same time?
Yes. Add both a Convert and Compress operation in the workspace. Operations are applied in order, so convert first, then compress for best results.
