Hi Product Hunt! ImageTool brings together three focused tools for one JPG or PNG image: compression for upload limits, independent width and height stretching, and overall brightness adjustment. All image processing happens locally in your browser, with no account or image upload required. The compressor lets you set a maximum in KB, add a minimum when needed, and choose exact dimensions or automatic resizing. It reports actual bytes, pixels and format. If your chosen limit cannot be met at fixed dimensions, it explains the problem instead of silently changing those dimensions. A minimum is a constraint to satisfy, not a promise to enlarge every tiny image. Image Stretcher changes the full image's proportions without cropping or adding borders. Image Brightener adjusts the whole image while preserving its dimensions. Both editors show Original and Result together, let you inspect either at full size, and export JPEG or PNG. Stretching does not restore missing detail, and the brightness control is a simple global adjustment, not AI enhancement or selective lighting repair. The 20, 50, 100 and 200KB compression tasks are available in English, Indonesian, Hindi and Nigerian English. The editors and additional guides are English-only. Editing does not automatically enforce a KB limit: save the edited file and select it in the compressor when you need both steps. The site includes public synthetic examples showing actual outputs and these tradeoffs. I'd like feedback on the comparison view and whether it is clear which tool to use for each task. Please use a synthetic or non-sensitive example if you want to share a case.
