Lösung
Compress images in your browser with local WebAssembly processing
ConV uses WebAssembly (WASM) compiled codecs — the same production-grade libraries (MozJPEG, libwebp, libavif, libpng) used by server-side image processing tools — running entirely in your browser tab.
Web Workers distribute encoding across CPU cores to keep the interface responsive. You get professional compression quality without installing software, without uploading files, and without depending on a cloud service.
The entire processing pipeline is client-side. Close the tab and no trace remains on any server.
Hauptvorteile
- Production-grade WASM codecs: MozJPEG, libwebp, libavif, libpng
- Web Workers for parallel, non-blocking encoding
- No installation, no plugins, no software
- Zero upload — fully client-side pipeline
Typische Anwendungsfälle
- Developers who want professional codec quality in a browser tool
- Teams who cannot install software on managed devices
- Privacy-conscious users who verify no network requests carry image data
- Users on multiple devices needing a consistent cross-platform tool
So funktioniert es
- 01
Browser loads WebAssembly codec modules on first use
- 02
Web Workers initialize codec instances in parallel threads
- 03
Encoding runs in worker threads — UI remains responsive
- 04
Encoded files are written to browser memory and offered for download
Einschränkungen und realistische Erwartungen
WASM module load adds a brief startup time on first use (~1–3 seconds for codec initialization). Very large images may exceed browser memory limits on constrained devices.
Häufig gestellte Fragen
What is WebAssembly (WASM) image compression?
WebAssembly lets production C/C++ codecs run in browsers at near-native speed. ConV uses WASM builds of MozJPEG, libwebp, and libavif — the same libraries used in server-side pipelines.
Does this run offline?
Once WASM modules are loaded, ConV can process images without a network connection.
How does browser-based compression compare to desktop software?
WASM codecs achieve near-identical output to their native equivalents. ConV's compression quality matches tools like ImageOptim or command-line MozJPEG.
Is this suitable for professional use?
Yes. ConV uses the same codecs as production image processing infrastructure. The outputs meet professional web publishing standards.

No-upload image optimizer for private workflows
Most image optimizers send your files to a remote server. ConV takes a different approach: the entire compression pipeline runs inside your browser using WebAssembly.
Convert images to AVIF locally in your browser
AVIF is the next-generation image format backed by the Alliance for Open Media. It achieves 30–50% better compression than JPEG at comparable visual quality and often outperforms WebP.
Compress multiple images locally and export them as ZIP
Processing images one at a time is impractical for agencies, content teams, and e-commerce workflows. ConV's batch mode handles dozens of images in a single session with parallel encoding and ZIP export.
