Frequently Asked Questions
Everything you need to know about bulk processing with Dopic.
How many images can I process at once?
You can upload and process between 50 to 100+ images in a single batch, depending on your device's memory and the complexity of the files. Our multi-threaded engine handles large loads efficiently.
Is my data safe? Do you store my photos?
Absolutely not. Dopic processes everything directly in your browser using local JavaScript and WebAssembly. Your images are never uploaded to our servers, ensuring 100% privacy and zero risk of data leakage.
Will the compressed images lose quality?
We use intelligent compression that minimizes file size while preserving visual fidelity. You can adjust the quality slider to control the trade-off between file weight and sharpness. For most use cases, the difference is imperceptible to the human eye.
Does this tool preserve the original DPI?
Yes. When you resize or compress images, Dopic maintains the original DPI (dots per inch) settings unless you explicitly change them. This ensures your images remain print-ready if needed.
Can I convert HEIC files to JPG in bulk?
Yes! Dopic supports batch conversion from HEIC (iPhone format) to JPG, PNG, or WebP. Simply select your HEIC files, choose the output format, and download the ZIP archive.
Is there a watermark on the processed images?
Never. Dopic provides clean, professional outputs with absolutely no watermarks, logos, or branding added to your images. They are ready for commercial use immediately.
