What is Image Compress?
Image compression reduces the file size of an image by lowering its quality or changing its encoding format. Lossy formats like JPEG and WebP discard visual data that the human eye is unlikely to notice, producing dramatically smaller files. PNG is lossless — it preserves every pixel exactly, so quality settings have no effect. This tool lets you pick a format and quality level, then instantly see how much space you save.
How to Use
- Upload an image — drag and drop or click "Choose Image" to browse.
- Pick an output format — JPEG or WebP for lossy compression. PNG is listed but produces lossless output.
- Adjust quality — drag the slider from 1 (smallest file) to 100 (highest quality).
- Click Compress — view original vs. compressed size, percentage savings, and a preview.
- Download — save the compressed image to your device.
Common Uses
- Web optimization — smaller images mean faster page loads and better Core Web Vitals scores.
- Email attachments — stay under inbox size limits by compressing photos before sending.
- Social media uploads — reduce upload time on slow connections without visible quality loss.
- Storage savings — free up disk space on phones and laptops by batch-compressing photo libraries.
