Why Compress Images?

Large image files slow down websites, take up storage space, and are difficult to share via email or messaging apps. Compressing images reduces file size significantly — often by 50–80% — while keeping the image visually sharp.

Web developers, bloggers, and social media managers compress images before uploading to improve page load speed and Google rankings. A 2MB photo can often be compressed to under 300KB with no visible quality loss.

Supported Image Formats

• JPG / JPEG — Most common format for photos. Excellent compression results.
• PNG — Lossless format. Compression reduces file size without altering pixels.
• WebP — Google's modern format. Compresses 25–35% better than JPG at similar quality.
• GIF — Animated image format. Compression supported.
• BMP — Uncompressed bitmap. Can be significantly reduced.
• HEIC — Apple's iPhone photo format. Compression supported via ImageMagick.

Frequently Asked Questions

Does image compression reduce quality?
At 60–80% quality setting, compression is nearly invisible to the human eye. Only at very low settings (below 30%) will you notice visible degradation. We recommend 60% for the best size-to-quality balance.

What is the maximum file size I can compress?
Free users can compress images up to 5MB per file. This covers the vast majority of photos taken on smartphones and digital cameras.

Can I compress PNG images?
Yes. PNG uses lossless compression, so our tool applies maximum compression level to reduce the file size as much as possible without changing any pixels. For the smallest file size, consider converting PNG to WebP or JPG.

Is my image safe after uploading?
Yes. Your image is processed on a secure server and automatically deleted within minutes of processing. We never store, share, or access your files.

Do I need to create an account?
No. The image compressor works without any registration. Just upload, compress, and download — completely free.
