Image compression
Compvert uses advanced lossy and lossless compression algorithms to reduce image file sizes while maintaining visual quality. For JPEG images, our tool applies intelligent compression that targets the optimal quality level — typically achieving 60–90% size reduction without visible quality loss.
PNG images are compressed using lossless algorithms that reduce file size without losing any image data. This is ideal for screenshots, logos, and graphics with transparent backgrounds. WebP format typically achieves 25–35% smaller file sizes than JPEG at equivalent quality.
Video compression
Video files can be compressed using H.264, H.265 (HEVC), VP9 or AV1 codecs. H.264 offers the best compatibility across devices and browsers. H.265 provides up to 50% better compression than H.264 at the same quality. You can also reduce the resolution, remove audio tracks and strip metadata to further reduce file size.
PDF compression
PDF files are compressed by optimizing embedded images, removing unnecessary metadata and applying lossless compression to document content. Our PDF compressor supports four compression levels — from screen quality (smallest file size) to prepress quality (maximum fidelity) — so you can choose the right balance for your needs.
Privacy & security
All files are uploaded over encrypted HTTPS connections and processed on secure servers. Uploaded files are automatically deleted from our servers 1 hour after download, or 6 hours if not downloaded. We do not analyze, share or sell your files or their contents. Metadata (EXIF, GPS location, camera info) is removed from compressed images by default.
