How to compress an image without losing quality
- Click "Compress Image" and select your JPG, PNG, or WebP file (up to 50 MB)
- Select Low compression to preserve maximum quality (~70% smaller, 85% JPEG quality)
- Download your compressed image — visually indistinguishable from the original at normal viewing sizes
What "85% JPEG quality" means in practice
JPEG quality is measured on a scale from 0 (worst) to 100 (best). At 85%, the human eye cannot detect any difference from the original under normal viewing conditions — on screen at 1:1 zoom or printed at standard sizes. This is the same quality setting used by Photoshop's "Save for Web" export and Google's recommended quality for web images. File size is roughly 30% of the original.
When to use each compression level
- Low (85%): CVs, portfolios, professional photography, images for print
- Medium (60%): Email attachments, social media, website thumbnails
- High (35%): File size limits on upload portals, maximum storage efficiency
