About this tool
Large images are one of the most common reasons web pages load slowly. The compressor re-encodes each image with a lower quality setting and can also scale it down to a maximum width, which together often reduce the size by 50 to 90% with little visible change.
JPEG files stay JPEG. PNG images are converted to WEBP, because PNG compression is lossless and cannot be tuned with a quality setting. If compression would make a file larger, the original is kept.
Frequently Asked Questions
- What quality should I use?
- 70 to 80% is a good balance for photographs. Use 85 to 90% when fine detail matters.
- Is compression reversible?
- No. Lossy compression discards detail, so keep your originals.
- Is it safe for private photos?
- Yes. The images are processed locally and never uploaded.
