Frequently Asked Questions

Find answers to common questions about ReducerImage and how client-side processing works.

Are my images secure on ReducerImage?
Yes, 100%! ReducerImage processes all files directly in your browser using HTML5 Canvas, WebGL, and Web Assembly. No files are ever uploaded to a server, ensuring your data is completely secure and private.
How does the watermark remover tool work?
When you brush over a watermark, we map the pixels of the brush stroke. A fast-marching, local patch-blending algorithm runs inside your browser to fill the area using colors from neighboring zones, recreating the texture.
Can I process multiple images in batches?
Absolutely! Our Compress and Convert tools support batch uploads. You can select up to 10 images at once, customize the compression quality or output format, process them together, and download them sequentially.
What formats are supported for conversion?
We support imports of JPG, PNG, WEBP, AVIF, HEIC, GIF, BMP, and SVG files. You can convert these files into PNG, JPEG, WEBP, AVIF, or raw BMP formats.
