¿Por Qué Comprimir Imágenes Antes de Publicar?
Heavy image files slow down page loading speeds, cause social media feeds to buffer, and eat up user bandwidth. Major social networks (like LinkedIn, X/Twitter, and Instagram) apply aggressive server-side compression algorithms to oversized uploads, which often ruins photo sharpness and degrades typography in graphics.
PreviewYourPost's 100% client-side compressor uses HTML5 Canvas and browser-native re-encoding to compress your PNG, JPEG, and WebP images directly on your machine. By maintaining complete control over image quality and resolution before uploading, your posts look crisp, professional, and load instantly across all devices.

Unlike traditional online compressors that upload your photos to external cloud servers, PreviewYourPost processes every image 100% locally inside your web browser using HTML5 Canvas and WebAssembly. Your photos, screenshots, and proprietary graphics never leave your device.
Standard photographs and heavy PNG screenshots typically see a 60% to 85% reduction in file size at the recommended 80% quality setting without any noticeable loss in visual clarity or sharpness on retina screens.
You can compress PNG, JPEG, JPG, and WebP files. When compressing PNG images with solid backgrounds, converting to JPEG or WebP unlocks massive byte savings while preserving crisp edge detail.
Large, unoptimized images cause mobile feed buffering, slower post loading times, and lower engagement. Furthermore, platforms like X (Twitter) and LinkedIn enforce strict upload thresholds (5MB to 10MB) and apply harsh server-side recompression if original files are too heavy.
Yes! You can drop up to 20 images at once (up to 25 MB per file). Each image is compressed in parallel, and you can download them individually or all at once.
We recommend setting the quality slider between 75% and 85%. This preserves crisp text readability in infographic carousels and vibrant color reproduction while keeping files lightweight.
