Compress locally instead of sending files to the cloud
Classic online compressors are convenient but not always compliant for sensitive work. ConV keeps originals on your device; outputs are built with WASM encoders right in the tab.
That workflow fits NDA work, internal marketing reviews, and deployments in regulated environments.
Comparable compression quality to popular cloud tools — without the privacy trade-off.
Beneficios clave
- MozJPEG, WebP, PNG, and AVIF WASM codecs — same quality as cloud tools
- No file upload — image bytes never touch a remote server
- Batch compression with ZIP export for fast CMS handoff
- Works for agencies, developers, and internal teams
Casos de uso habituales
- Marketing teams compressing campaign images under NDAs
- Agencies processing client photos without cloud data exposure
- Developers building assets for performance-sensitive web projects
- E-commerce teams preparing product image batches

Download a ZIP of all compressed files
Limitaciones y expectativas realistas
Compression results depend on source image content and your quality settings. ConV does not guarantee a specific file size reduction for every image.
Preguntas frecuentes
How does compression quality compare to TinyPNG?
ConV uses the same underlying codecs (MozJPEG, libwebp) as many popular cloud tools. Results are comparable for typical photos and graphics.
Are my images sent to any server?
No. All compression runs locally in your browser. No image data is transmitted.
Can I compress RAW photo files?
No. ConV works with JPEG, PNG, WebP, and AVIF. RAW formats (CR2, NEF, etc.) are not supported.
Is there a file size limit?
Very large individual files (above several hundred MB) may hit browser memory limits. Most standard web images are well within limits.

A TinyPNG-style workflow — with a zero-upload guarantee
TinyPNG and similar tools are great for consumers. B2B teams often need auditable data flows. ConV removes the upload path entirely.
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.
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.
