Lösung
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.
Drop an entire folder of images, set a global preset, and download a ZIP of all compressed outputs. No file-by-file manual processing.
Pro users can process unlimited images per session — practical for large catalog runs or campaign asset sets.

Einschränkungen und realistische Erwartungen
Batch processing speed depends on your device's CPU and available RAM. Very large batches (100+ high-resolution images) may require patience on slower hardware.
Häufig gestellte Fragen
How many images can I process at once?
Free tier: up to 20 images per session. ConV Pro: unlimited images per session.
Does the ZIP preserve my original filenames?
Yes. Output files in the ZIP use the original filename with the new extension (e.g., photo.jpg → photo.webp).
Can I mix JPEG and PNG inputs in one batch?
Yes. You can drop a mix of JPEG, PNG, WebP, and AVIF files and set a single output format for the whole batch.
Are images uploaded during batch processing?
No. All encoding happens locally in your browser. No files are transmitted.

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 WebP without uploading them
WebP is the de-facto standard for web images. Converting to it typically reduces file size by 25–35% compared to JPEG, improving page speed and Core Web Vitals without loss of quality.
Optimize Shopify product images locally
Large product images slow Shopify stores and hurt Core Web Vitals scores. ConV lets you compress and convert product images to WebP or AVIF locally before uploading them to Shopify.
