ImgConvertFree's image compressor tool lets you reduce the file size of JPG and PNG images directly in your browser — no upload to any server required. Simply select your image, choose your desired quality level, and click compress. Your compressed image is ready to download in seconds.

Our compression algorithm reduces file sizes by up to 90% while maintaining excellent visual quality. This makes it perfect for web use, email attachments, social media uploads, and saving storage space.

Frequently Asked Questions

How much can I compress an image? +
Depending on the original image and your quality setting, you can reduce file size by 30% to 90%. A 5MB photo can easily become under 500KB without visible quality loss at 75% quality setting.
Is my image uploaded to a server? +
No. All compression happens locally in your browser using JavaScript. Your images are never sent to any server, making this tool completely private and secure.
What image formats are supported? +
Our compressor supports JPG/JPEG, PNG, and WebP formats. The output is always in the same format as your input file.
Is there a file size limit? +
There is no server-side file size limit since processing is done in your browser. Very large files (over 50MB) may take a few extra seconds depending on your device's processing power.
What quality setting should I use? +
For web use and social media, 70–80% quality gives the best balance of file size and visual quality. For professional printing, use 85–95%. For thumbnails and previews, 50–65% is fine.
