100% Secure & Private Processing

Unlike conventional online compressors, our tool processes images entirely inside your web browser using JavaScript HTML5 Canvas APIs. Your photos are never uploaded to our servers, ensuring total privacy and data confidentiality.

Targeting Specific File Sizes (20KB, 50KB, 100KB)

Many government portals, job applications, and university forms require uploaded images to fit below strict limits like 20KB or 50KB. While setting lower quality percentage reduces file size, large high-resolution photos may also require scaling dimensions down to strictly hit smaller target KB thresholds.

Format Conversion & Technical Limitations

Understanding how different file extensions behave helps in choosing the right output settings:

PNG to JPG Conversion: PNG files are uncompressed/lossless and larger in file size. Converting PNGs to JPG significantly shrinks size but removes background transparency.
WebP Format: WebP offers superior compression compared to JPG at similar quality, though older legacy devices may not support it.
Quality Loss Expectation: Lossy compression (JPG/WebP) removes imperceptible pixel data to reduce file weight. Fine-tuning the quality slider ensures your image remains visually sharp to the naked eye.

Frequently Asked Questions (FAQ)

Q: Will reducing image size compromise visual quality?

A: Lossy compression removes minor photographic details that the human eye rarely notices. Setting quality between 75% and 85% usually reduces file size drastically with no visible loss in sharpness.

Q: Why did my PNG image change to JPG upon downloading?

A: PNGs use lossless compression which keeps file sizes large. Defaulting compression to JPG allows the tool to achieve maximum file size reduction. You can manually re-select PNG output from our settings if needed.

Q: Can I use this tool offline?

A: Yes! Once the webpage is loaded, the entire compression script runs client-side inside your browser memory without requiring an active internet connection to process images.
