Home › Image Compressor — Exact KB Target
Compress any photo to an exact KB target — 20KB, 50KB, 100KB, 200KB or custom — for forms, applications and portals.
Government portals, exam forms, visa applications and job sites all demand photos under exact size caps — 20KB, 50KB, 100KB. This compressor hits the target precisely: it binary-searches the JPEG quality (and, when needed, the dimensions) until the file lands just under your limit, then shows the result with the exact size and savings. Presets for the common caps, a custom field for everything else, JPG or WebP output — and like every iConvertDoc tool, the photo is processed entirely on your device. When you're done, send the result straight to the Photo Editor with one click.
It binary-searches the compression quality across seven rounds, and if even the lowest acceptable quality is too large, it scales dimensions down and searches again — so the result is the best-looking image that fits under your number.
The output is a standard JPG (or WebP if you choose). Dimensions are only reduced when mathematically necessary, so the photo stays as sharp as your target allows.
No — compression runs in your browser. It works even offline once the page is loaded.
Possible for small dimensions; the tool will shrink the image until it fits. For face photos on forms, pairing this with the Passport Photo Maker's exact-size crop gives the best results.
Currently one at a time for precision. For bulk size reduction without an exact target, the Image Converter's quality slider zips a whole batch.
