The Image Resizer & Compressor lets you resize images to specific dimensions and compress them to reduce file size — all entirely in your browser. No images are uploaded to any server.
Supports JPEG, PNG, and WebP output formats. The quality slider (for JPEG and WebP) lets you balance between file size and visual quality. Perfect for optimizing images for websites, emails, or social media.
No, all processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
WebP generally provides the best compression with good quality. JPEG is a good fallback for wider compatibility. PNG is lossless but produces larger files.
There's no hard limit, but very large images (10,000+ pixels) may be slow to process depending on your device's capabilities.
PNG is a lossless format — it preserves all image data. Quality/compression only applies to lossy formats like JPEG and WebP.
