Questions
Everything you need to know about compressing images with untinyJPG.
At 80% quality (our recommended default), compression is virtually invisible to the human eye — even on screens. You save 50–70% of the file size with no perceptible loss. Dropping to 60% is still excellent for web use. Only at very low settings (below 40%) do compression artifacts become noticeable.
You can upload JPG, PNG, and WebP images. The output format always matches your input — so a JPG in gives a JPG out, and so on.
No. Your images are automatically deleted within 2 hours of compression, and immediately upon download. We never store, share, or use your images for any purpose.
