Free Image Compressor Online — Reduce JPG PNG WebP Size Without Quality Loss
Compress JPEG, PNG and WebP images by up to 80% with no visible quality loss. Our tool automatically selects the best compression algorithm for each file type. No software, no account — files deleted after 1 hour.
Smart compression by file type
JPEG/JPG images use lossy compression: our tool finds the optimal quality level (typically 75–85%) that produces the maximum file size reduction while keeping the image visually identical to the human eye. PNG images use lossless compression with quantization: colors are intelligently reduced from 24-bit to an optimized palette, shrinking file size by 40–70% with imperceptible quality change. WebP uses Google's modern codec which delivers 25–35% better compression than JPEG at equivalent quality.
Why image compression matters for web performance
Page speed is a confirmed Google ranking factor. Heavy images are the #1 cause of slow websites. A page that loads in 2 seconds converts 3x better than one loading in 5 seconds. Compressing images to under 200 KB each reduces page weight dramatically, improves Core Web Vitals (LCP, CLS) and delivers a faster experience on mobile connections. Our compressor produces web-optimized images that meet Google PageSpeed and Lighthouse recommendations.
Batch compression
Upload and compress up to 20 images in one batch. All compressed files are available for individual download or as a single ZIP archive. The original file names are preserved so you can directly replace files in your project without renaming.
FAQ
Does compression make images blurry?
No. Our tool applies compression at a quality level where the difference is imperceptible to the human eye. JPEG compression at 75-85% quality is visually identical to the original at a fraction of the file size.
Which formats are supported?
JPG, JPEG, PNG and WebP as input. The compressed output uses the same format as the input.
Can I compress images for social media?
Yes. Facebook, Instagram, Twitter and LinkedIn all recompress uploaded images anyway. Pre-compressing your images ensures they pass size limits without the platforms applying their own (often lower-quality) compression.
What is the maximum file size per image?
Each image can be up to 20 MB. Batch upload supports up to 20 images at once.
Is there a difference between compressing PNG and JPEG?
Yes. JPEG uses lossy compression (some data is permanently removed). PNG uses lossless compression with color quantization (all original pixels can be reconstructed). For photographs, JPEG is more efficient. For logos, icons and screenshots with flat colors, PNG compression is better.
Can I compare the original and compressed image before downloading?
Yes. A side-by-side preview shows the original vs compressed image along with file size reduction percentage before you confirm the download.
