Bulk Image Compressor & Resizer | Batch Process 100+ Photos - Dopic
Everything you need to know about processing large batches of images safely.
Absolutely. Dopic uses client-side processing. Your images are processed entirely within your browser's memory and are never uploaded to any external server. This ensures complete privacy and security for sensitive business or personal photos.
You can upload and process between 50 to over 100 images in a single batch, depending on your device's performance. The tool utilises multi-threading to handle large volumes efficiently without crashing your browser.
Dopic uses advanced smart-compression algorithms that maintain visual fidelity. You can adjust the quality slider to find the perfect balance between file size reduction and image sharpness. We prioritise preserving DPI and colour accuracy.
Currently, bulk operations apply uniform settings (same width/height and compression level) to all selected images to ensure consistency. For mixed-size needs, we recommend grouping images by required dimensions.
While Dopic is optimised for desktop browsers (Chrome, Edge, Firefox, Safari) due to the heavy computational load, it may work on powerful tablets. For best performance with 50+ images, we recommend using a laptop or desktop computer.
