Why CompressTo?
Most "compress my photo" sites are SEO-driven uploaders with stacked ads, slow uploads, and zero awareness of the actual rule your form is enforcing. CompressTo is built for one job: get your file accepted on the first try. The tools enforce the official spec — file size, dimensions, aspect ratio, format — and the result panel tells you per-constraint what passed.
Three things we do differently
- Nothing uploaded. Every compression runs in your browser using the Canvas API and Web Workers. We do not store, log, share, or even see your files. You can verify this in your browser's Network tab — there are no upload requests.
- 98 verified application presets. Each preset is wired up from the official source bulletin (UPSC, NTA, NEET, CMAT, IBPS, India e-Visa, US DS-160, UK passport, Canada PR, LinkedIn, Google Ads — and many more). Spec changes are tracked and dated.
- Real compliance feedback. After compression, the result panel shows per-constraint pass / warn / fail — file size, dimensions, aspect ratio, format, plus a basic background-whiteness check on photo presets.
