Why Compress Images Online?

Website performance and loading speeds are critical aspects of both User Experience (UX) and Search Engine Optimization (SEO). Unoptimized, massive image files are one of the biggest culprits of slow-loading pages.

Our free online image compressor uses advanced browser-based Canvas processing to shrink your image filesize immensely without discernible quality loss—and because it runs strictly inside your local browser, no data is uploaded to our servers, keeping your photos 100% private.

WebP to JPG Converter

Convert and compress modern formats effortlessly. By leveraging modern codecs built right into your browser, you can easily handle webp to jpg workflows and slash filesizes across formats while maintaining maximum fidelity.

HEIC to JPG Compiler

iPhone photos look great, but the .heic container isn't friendly for all websites. We securely convert heic to jpg completely locally and compress it up to 80% with our photo compressor.

Faster Page Speeds

Lighter web pages result in improved Core Web Vitals (like LCP) and lower bounce rates. Keep your traffic high and your visitors happy by squashing huge bloated photos before uploading them to your CMS.

100% Client-Side Privacy

Other image tools upload your camera rolls to cloud servers where they can be retained. We use the HTML5 Canvas API to compress and resize the image locally inside your computer's RAM.

No, to offer you the absolute best compression filesize possible, the image generator primarily aims to output as a compressed JPEG. During this process, our system will fill any transparent backgrounds with a solid white matte to avoid rendering visual glitches.

Yes, keeping true to the browser limits and preventing out-of-memory RAM errors, our online image compressor currently handles individual image photos up to a maximum size of 20 Megabytes (20MB).
