Multiple files OK · everything stays in your browser
Faster pages, smaller files
Photos from modern phone cameras are typically 4-8 MB. That's overkill for the web — most browsers display images at 1200 px wide max. We resize to your target max dimensions and re-encode at high quality (default 80%), typically cutting file size by 60-80%.
All processing happens in your browser using the canvas API. Your image never leaves your device — safe for unpublished photos, client work, or sensitive content.
Frequently Asked Questions
How much smaller will my image be?▾
Typically 40-80% smaller depending on the original. Photos from phone cameras (often 4-8 MB) compress to 200-800 KB without visible quality loss. Already-optimized images compress less. Use the quality slider to balance file size vs visual quality.
Is my image sent to a server?▾
No. Compression happens entirely in your browser using the Canvas API and the browser-image-compression library. Your photos never leave your device — perfect for sensitive or unpublished images.
JPG vs PNG vs WebP — which should I use?▾
Photos: JPG or WebP. Graphics with transparency or sharp edges (logos, icons, screenshots): PNG or WebP. WebP is the best modern format — 25-35% smaller than JPG at the same quality, supported in all current browsers since 2020.
Will compression hurt SEO?▾
The opposite. Smaller images = faster page loads = better Core Web Vitals = better rankings. Google's Largest Contentful Paint (LCP) metric directly measures hero image size; cutting your hero from 800KB to 80KB can lift you from "Poor" to "Good" instantly.
Why does the output sometimes look the same?▾
Image compression is lossy: it removes detail your eye doesn't notice. At 80%+ quality, most viewers see no difference. Below 60% you may notice artifacts in flat color areas (gradients, skies, skin). Always preview before using on important visuals.
