Free Image Compressor Online - Compress JPG, PNG & WebP Without Losing Quality

Yes, completely free with no signup, no watermarks, and no usage limits. Compress as many images as you need.

At 80–90% quality setting, the difference is invisible to the human eye in most images. You can use the quality slider to find the perfect balance for your specific images.

No. All compression happens locally in your browser using the HTML5 Canvas API. Your images never leave your device — no server uploads, no cloud storage, no data retention.

Typically 40–90% depending on the original image and format. JPG photos at 80% quality often compress to 50–70% of their original size. Converting PNG to WebP can reduce size by 30–50% with no visible difference.

WebP is the best choice for most websites — 25–35% smaller than JPG at equivalent quality. AVIF is even better (up to 50% smaller) and is supported by all modern browsers. Both formats directly improve Google Core Web Vitals LCP scores.

Yes. WebP produces files 25–35% smaller than JPG at the same visual quality level. Google recommends serving images in WebP or AVIF format to pass Core Web Vitals assessments.

80–90% is the sweet spot for web use — excellent visual quality with 40–60% smaller file sizes. Use 60–75% for maximum compression where quality loss is acceptable (thumbnails, social media). Use 95–100% for print or professional output.

Yes. Upload multiple images, set your quality and format preferences, and compress them all simultaneously. Download individually or as a single ZIP archive.

Yes, directly. Compressed images improve page load speed, which improves Largest Contentful Paint (LCP) — a Google Core Web Vitals metric used as a ranking signal. Faster pages rank higher, especially on mobile searches.

Lossy compression (JPG, WebP) removes some image data to achieve significant size reduction — at 80%+ quality the difference is invisible. Lossless compression (PNG) reorganizes data without losing any information — perfect quality but larger files. Use lossy for photos, lossless for logos and screenshots.

Images are typically the largest content element on a page, so they directly affect Largest Contentful Paint (LCP). Reducing image file size means faster download and rendering, which lowers LCP time. Google's PageSpeed Insights will flag large images as a critical fix.

Yes. Product image compression is one of the highest-impact SEO improvements for e-commerce sites. Compress product photos to WebP at 80–85% quality — pages load faster, conversions improve, and PageSpeed scores increase.

No server-side limit. The compressor runs in your browser, so performance depends on your device memory. Very large images (20MB+) may take a few extra seconds to process.

Yes. PNG compression is lossless and preserves transparency. If you convert PNG to WebP, transparency is also preserved since WebP supports alpha channels.

Progressive JPEG loads images in stages (blurry to sharp) rather than top-to-bottom, giving users faster perceived load times. This tool generates progressive JPEGs by default, which is recommended for web use.

Yes. The tool is fully responsive and works on any modern mobile browser without installing an app.

No watermarks ever. Your compressed images are completely clean and ready to use.

Yes. Many email clients block images over 1MB. Compress your images to under 200KB for reliable email delivery and faster inbox previews.

TinyPNG and Squoosh upload your files to their servers for processing. Our compressor is 100% browser-based — your images never leave your device, giving you stronger privacy guarantees.

Yes. Once the page is loaded, compression runs entirely in your browser and does not require an active internet connection.
