Precision-engineered color converter, picker & palette generator for the modern web.
About Color Converter, Picker & Palette Generator
Color Converter, Picker & Palette Generator is a fast, private, browser-only image utility designed around a local-first architecture. It handles common image formats, preserves colour profiles and EXIF metadata on request, and produces clean, web-ready output suitable for production sites. Processing takes place using a WebAssembly engine, so you get consistent, high-quality results without ever uploading source images to a cloud service — ideal for teams with strict privacy requirements.
Problems This Tool Solves
Uploading photos and brand assets to online converters is an uncomfortable privacy trade-off. - Color Converter, Picker & Palette Generator keeps every image on your device by processing in-browser with WebAssembly.
Free online image tools often apply watermarks, strip EXIF silently or degrade colour profiles. - Color Converter, Picker & Palette Generator preserves colour spaces, optionally keeps EXIF and never adds watermarks.
Batch-processing large sets of images in Photoshop is slow and requires a paid licence. - Color Converter, Picker & Palette Generator handles batch operations directly in the browser with no install and no licence.
Quota-limited web tools stop working when you need them most — in the middle of a project. - Color Converter, Picker & Palette Generator has no quota. Process 10 images or 10,000; the limit is your device, not a paywall.
How to Use
Drop your image - Drag a single file or a batch — JPG, PNG, WebP, AVIF, GIF or SVG.
Choose the operation - Convert, resize, compress, recolour or extract data — all from the same workspace.
Preview the result - See before/after side-by-side along with file-size and dimension readouts.
Download - Save individually or as a bundled ZIP for batch workflows.
Why This Tool Is Better
Desktop-grade codecs - WebAssembly ports of libvips, libwebp and AVIF produce results on par with ImageMagick and Photoshop.
Private by design - Photos and brand assets never leave your browser, which matters for client work and personal content.
No watermarks, ever - Every export is clean, unbranded and ready for production use.
