Useful to know
Quality vs file size
Lower quality settings shrink files but introduce artifacts in flat areas like skies and skin. For most photos, 70-85% quality is visually indistinguishable from the original at typical viewing sizes.
What gets compressed
ImgShifter compresses JPG, PNG, and WEBP locally in your browser. PNG compression is lossless. JPG and WEBP are lossy, so re-compressing the same file repeatedly will compound quality loss.

Compress online with ImgShifter
Compress Image keeps the workflow simple: upload an image, adjust the settings, preview the result, and download the finished file. The page is built for speed, responsive layouts, and search-friendly content, with no signup required.
Common formats like PNG, JPG, and WEBP run entirely in the browser using the Canvas API, so files never leave the device. For heavier formats — HEIC, AVIF, TIFF, RAW, and SVG — ImgShifter routes the work to its conversion service while keeping the same upload, preview, and download flow.
