Useful to know
Downscale vs upscale
Downscaling is safe and often makes images look sharper. Upscaling beyond the original adds no real detail and tends to look soft - use a dedicated AI upscaler if you need that.
Aspect ratio lock
Keeping the lock on prevents stretching. Disable it only when you need exact dimensions and are prepared to crop or letterbox the difference yourself.

Resize online with ImgShifter
Resize 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.
