Compression
This tool only reduces file size (encoding). It does not change width or height in pixels. To change dimensions, use the image resizer or an image converter.
Smaller file 80% Sharper image
How heavily the encoder compresses (similar to “JPEG quality”). Lower values make a smaller download but can show blockiness or soft detail. PNG with graphics may change less than photos. Extremely large images can still hit your browser’s canvas limits when decoding.

About the Image Compressor
Upload an image and reduce file size for websites, CMS uploads, and content handoffs—tune quality while keeping dimensions for supported formats.
Shrink assets before publishing
Compression trades some quality for smaller downloads. Use the quality control when CMS budgets or page-weight targets matter more than keeping an oversized source file.
Resize first with the Image Resizer, crop with the Image Cropper, combine shots in the Image Merger, or caption graphics in the Meme Creator.
Tune compression quality
Balance smaller file size against detail retention with the quality control before downloading.
Meet CMS and web budgets
Compress before uploading to a CMS or placing assets on landing pages, product pages, and blogs.
