What This Site Is
Images in Constant Flux is a collection of 31 free image tools covering format conversion (PNG, JPG, WebP, GIF, AVIF, HEIC, TIFF, BMP), compression, resizing and cropping, background removal, watermarking, base64 encoding, EXIF reading, and long-image workflows. Every tool runs entirely in your browser using JavaScript — the files you work with are never uploaded to a server.
Why We Built It
Most image tool sites ask you to upload private screenshots, contracts, and client photos to a stranger's server just to rename a file format. We wanted the opposite: tools that respect the files by never taking them. Browser-side processing is also faster — no upload queue, no waiting room.
How the Tools Work
Conversion and compression use the browser's native image decoding wherever possible, with a hand-built GIF frame decoder and battle-tested open-source libraries (UTIF for TIFF, heic2any for HEIC) loaded from a public CDN for the formats browsers can't read natively. Each tool page states exactly what it does — and what it honestly can't, like true vector tracing.
Our Standards
Tool behavior is verified before publication — the GIF decoder alone passes a 13-case unit suite including real-world files. Pages describe limitations plainly rather than overselling. If a tool can't do something, the page says so.
The Short Version
Free tools, no accounts, no uploads, stated assumptions, and a working contact path. That's the whole promise.
