Free Image Compressor Online

Compress images online without uploading to a server

Large hero images slow pages and blow past email attachment limits. This free image compressor shrinks JPG, PNG, and WEBP files in your browser—adjust quality, cap dimensions, optionally convert to WEBP, and compare before/after previews with exact byte savings.

Workflow tips

Drop multiple files for batch compression during content launches. Use WEBP output for modern browsers while keeping PNG when you need lossless transparency. Pair with our image to Base64 tool when you need inline data URLs, or the QR code generator for scannable marketing assets.

Quality versus size

Start around 75% quality for photos; raise it for screenshots with text. Lower max width when thumbnails are the target—resize often saves more bytes than aggressive quality cuts alone.
