About StackImage

Private image tools that never leave your browser

StackImage is the image sibling of StackPDF, built by Stack Tools. We make simple, privacy-first image tools as an alternative to suites that upload your photos to process them.

Eighteen tools run in the browser today. Compress, convert (including HEIC), crop, and the on-device Enhance tools — remove background and upscale — are the core. Each page states what you actually get, including format limits and quality tradeoffs.

Image processing never leaves your tab. There is no account, no upload API, and no server-side pipeline for your files. Enhance tools only fetch model weights from our storage; your photo stays on the device.
