FAQ
Does compressing an image reduce its visual quality?
At moderate compression levels (70–85%), the quality loss is invisible to the human eye in most use cases. PdfPixels' 1–100 slider lets you find the sweet spot between file size and quality for your specific image, whereas iLovePDF's preset system applies fixed reductions. For critical images, always compare the original and compressed versions before publishing.
Which tool is better for bulk image compression?
Both tools process one image at a time in their free tiers. For bulk compression of many images, consider a desktop tool like ImageOptim (Mac) or FileOptimizer (Windows). For web developers, build-time tools like imagemin or Squoosh CLI are better suited to automating compression across hundreds of images.
