About This Tool
How Image Compression Works
JPG and WebP use lossy compression – they discard information the human eye is least likely to notice. Lower quality settings discard more, producing smaller files.
What Quality Setting Should I Use?
- 90-100% – Visually identical to original; small size savings
- 75-85% – Sweet spot for most photos; ~50-70% smaller
- 50-70% – Web-friendly; ~80% smaller, slight artifacts
- Below 50% – Visible blockiness; only for thumbnails
Format Recommendations
- Photos: JPG or WebP
- Graphics, logos, screenshots: PNG (lossless) or WebP
- Modern web: WebP delivers 25-35% smaller files than JPG
Frequently Asked Questions
Why does PNG compression not reduce the size much?
PNG is a lossless format - no pixel data is discarded. The quality slider only affects JPG and WebP. To shrink PNGs significantly, either resize them smaller or convert to JPG/WebP if the image is photographic.
Should I use WebP everywhere?
WebP is supported by all modern browsers (since 2020) and gives 25-35% smaller files than JPG at the same visual quality. Use it for the web. For email or older systems, stick with JPG. PNG is still best when you need transparency in non-photo content.
Why does my compressed file seem identical in size to the original?
If you are compressing an already-compressed file (e.g., a JPG saved at 70% quality), recompressing at 80% may produce a similar or even larger file because of the format overhead. Always start with the original/highest-quality source.
