Free Online Image Processing Tools
Convert PNG images in batch and generate AI grayscale heightmaps right in your browser — no account, no limits, files deleted right after processing.
详细介绍
imagetool.cc is a free online image toolkit for designers, developers and 3D creators. Its core features include batch PNG conversion to WebP, GIF or JPG, plus AI grayscale heightmap generation. Tools run in your browser or through secure cloud processing, with no software installation or account required.
Unlike services such as CloudConvert, imagetool.cc focuses on free access, no sign-up and privacy-conscious processing. Files are handled only as needed for conversion or generation and are not retained as a permanent library. Batch-select PNG files to prepare product photography, game assets and app icons, then download the results together as a ZIP.
Format conversion supports separate image and canvas dimensions, with each image centered on its output canvas. The grayscale heightmap tool serves 3D modeling, material displacement, CNC relief and 3D printing workflows. It offers quick local processing and cloud AI monocular-depth inference, with up to four candidates to compare.
The tools are free to use without usage quotas. Whether you are preparing one image or a batch of assets, you can start directly in the browser without a subscription or paywall.
