About Image Compression
Image compression reduces file size by re-encoding pixels more efficiently. Lossless compression (PNG, WebP lossless) preserves exact pixel data; lossy compression (JPG, WebP lossy, AVIF, HEIC) discards imperceptible detail. Either way, the image looks the same at normal viewing size — it's just smaller.
Exam & Form Uploads
Portals like SSC, UPSC, IBPS, PPSC, FPSC, and visa applications require photos and signatures under 20KB–200KB. Our target-size pages hit those limits automatically.
Web Performance
Smaller images mean faster websites. Modern formats (WebP, AVIF, JXL) plus compression can cut page weight by 60–80%.
Cloud Storage & Email
Compress photos before uploading to Drive, iCloud, or sending by email. Saves storage quota and avoids attachment limits.
Format Preservation
Unlike converters, compressors preserve the original format. Upload a HEIC, get a smaller HEIC. Upload JXL, get smaller JXL.
