Compress JPG, PNG, WebP up to 80% without losing quality
Supported:JPGPNGWebPBMP(Max 50MB)
Reduce JPG, PNG, and WebP file sizes by up to 90% without sacrificing visual sharpness using browser-native Canvas compression algorithms.
Compress JPG, PNG, WebP up to 80% without losing quality
Your photos are compressed using HTML5 Canvas APIs inside your browser memory; zero bytes are ever uploaded to any cloud server.
Fine-tune quality sliders from 1% to 100% with real-time file size estimation before downloading.
Compress unlimited images of any resolution without paywalls, email sign-ups, or artificial daily quotas.
Intelligently handles alpha transparency in PNG and WebP assets to avoid blackened backgrounds.
Softnag Image Compressor leverages modern HTML5 Canvas 2D rasterization and native browser encoding subroutines (such as canvas.toBlob). When you drop an image, the browser decodes the compressed bitstream into an uncompressed RGBA pixel buffer in local memory.
Upon adjusting the target compression slider, our algorithm computes optimized quantization matrices and re-encodes the image stream with lossy or lossless parameters. Because the computation runs in a dedicated client thread, compression executes almost instantaneously even on multi-megapixel photos.
Unlike traditional cloud compressors that queue your confidential files on remote servers, Softnag provides absolute privacy with zero latency and zero data transfer overhead.
Shrink hero banners and blog illustrations to sub-100KB to boost Google PageSpeed scores.
Comply with government and HR upload restrictions that mandate photos under 200KB or 500KB.
Avoid 25MB attachment bounce-backs by compressing batches of presentation slides and screenshots.
Reduce Android APK and iOS bundle sizes by optimizing embedded graphic assets.
For standard photographic JPEGs, setting quality between 75% and 85% typically reduces file size by 60% to 80% with virtually imperceptible perceptual degradation.
No. Softnag operates purely on client-side Web APIs. All decoding, compression, and encoding occur locally within your browser sandbox.
Yes. The compressor automatically preserves alpha transparency when exporting to PNG or WebP formats.
Because processing happens on your local device, the tool comfortably handles single images up to 50MB–100MB depending on your available system RAM.
Canvas re-encoding strips sensitive GPS coordinates and camera metadata by default, enhancing your digital privacy.
Client-side compression eliminates the upload time (sending 15MB over home broadband) and download wait time, performing the math directly on your device GPU/CPU.
No. Softnag processes all images directly in your browser using HTML5 Canvas and WebAssembly. Your photos remain private in your local device memory.
You can compress JPG, JPEG, PNG, WebP, BMP, and GIF files.
By default, pixel dimensions stay identical while redundant metadata bytes and color tables are optimized.
