Frequently Asked Questions
Will my image look blurry after compression?▼
No. Our image compressor online uses smart lossy compression for JPGs and lossless compression for PNGs. At the recommended 80% quality setting, the human eye cannot detect the difference between the original and the compressed version.
How can I compress image to 50kb for online applications?▼
Upload your photo and gradually drag the quality slider to the left until the estimated output size drops below 50kb. If the file is still too large, you may need to use our Image Resize tool first to reduce the physical dimensions.
Are my personal photos uploaded to your servers?▼
Never. Unlike other services, all image compression happens locally inside your web browser using HTML5 Canvas APIs. Your private photos never leave your device, ensuring 100% privacy.
What is the difference between compressing a JPG and a PNG?▼
JPG compression is "lossy," meaning it permanently removes some colour data to drastically reduce file size, which is perfect for photographs. PNG compression is "lossless" and optimizes how the data is stored without altering the pixels, which is ideal for logos and graphics with transparent backgrounds.
