📋 How to Use
- Upload an image.
- Choose JPEG or WEBP and set the quality slider (1–100).
- Download the compressed file.
JPEG has no transparency. Processing happens in your browser.
Image Compress
Drag the quality slider and watch the file size drop in real-time. Export as JPEG or WEBP. The compression runs entirely in your browser — your image is never uploaded.

💡 Example
📝 Blog and article images
Large images slow down page loading, which hurts both user experience and SEO rankings. Compress blog images to under 200 KB each before uploading. At quality 75–80%, most photos look identical to the originals but load noticeably faster.
🛍️ Product photos for e-commerce
Online stores with many product images benefit most from compression. A product gallery that loads in 1 second rather than 5 seconds keeps shoppers engaged. Use WEBP format at quality 80 for the best balance of size and visual quality.
📤 Sharing through messaging apps
KakaoTalk and other messaging apps often compress photos automatically, which can reduce quality. Compress the image yourself first at a quality you're happy with, then share — you control the output quality rather than leaving it to the app.
✨ About lossy compression
Lower quality means smaller files and more artifacts—preview when possible.
JPEG cannot store alpha. Transparent PNGs may get a solid background—keep PNG or use WEBP if you need transparency.
Highlights
- JPEG or WEBP output with a 1–100 quality slider.
- WEBP often beats JPEG at the same quality for size.
- No server upload.
Web performance, email attachments, and CMS upload limits.
Good use cases
- Phone photos for the web
- WEBP for smaller files at similar quality
- Stay under upload size caps
- Keep the same dimensions but shrink bytes
Compared with resize
Compress changes encoding quality; Resize changes pixel dimensions. Use both if needed.
Always eyeball the result before publishing.
❓ Frequently Asked Questions
- Q. Is it really free?
- Yes. This compress tool is offered at no charge.
- Q. Do I need to sign up?
- No. Use it directly on this page.
- Q. Are images uploaded to a server?
- No. Compression runs only in your browser; files are not sent to Webooro servers.
- Q. JPEG or WEBP—which should I use?
- WEBP typically gives smaller files at the same quality. Use WEBP for web optimization, JPEG for maximum compatibility.
- Q. Can I keep transparency?
- JPEG does not support transparency. For transparent backgrounds, save as PNG or use the Image Converter for format-only conversion.
- Q. Can I compress PNG files too?
- PNG uses lossless compression so size reduction is less dramatic than JPG or WEBP. For large size savings on a PNG, convert it to WEBP or JPG using the Image Converter tool instead.
- Q. Can I compress multiple images at once?
- Currently one image at a time. Upload each image separately — all processing is in the browser so each compression finishes quickly.
- Q. Can I compare file size before and after?
- Yes. The result screen shows the original size and the compressed size side by side so you can see exactly how much was saved.
