About GPJam Image Tools
GPJam Image Tools is a collection of 1198+ free image tools built on one principle: your images should never have to leave your device to be edited.
What we build
Compression to an exact KB, pixel- and unit-perfect resizing, passport photos, format conversion, image-to-PDF, cropping, a full effects studio, a collage maker and more — all running locally in your browser. Browse the full tool list or our guides.
How it works
Modern browsers can do serious image processing: the Canvas API resamples and re-encodes pixels, WebAssembly runs codecs and even neural networks, and WebGPU accelerates the heavy lifting. We use these to do everything on-device — which is why there is no upload, no queue and no privacy risk. Read more on our privacy page.
Our principles
- Private by design — no upload, ever.
- Free and open — no signup, no watermark, no paid AI APIs.
