Compress an image to 200 KB

Scanned documents, marksheets, certificates and some photo boxes use 200 KB because it keeps text and signatures readable. The exact ceiling, pixel size and format come from the portal you are applying to — check its instructions rather than assuming.

Sometimes. A 12 MP phone photo rarely fits; a scan or a screenshot often does. The engine tries quality first and then a bounded set of downscales, and it reports the dimensions it actually used, so you can see whether the original size survived.

PNG is lossless, so quality steps do nothing. At this budget the only lever is fewer pixels, and a detailed PNG still loses. Switch the output format to JPEG or WebP for photographs and scans; keep PNG only when transparency or exact pixels matter.

It should look better, because there are more bytes for the same pixels. The ceiling is a limit, not a target to beat: compress to the largest size the portal accepts, which is why this page defaults to 200 KB instead of pushing lower.

No. Decoding, resizing and encoding happen inside the page. Nothing is posted anywhere, and you can disconnect the network after the page loads.

The bulk compressor takes up to 30 images per run and returns one ZIP. For PDFs, merge or split first — this project does not compress PDFs, because meaningful PDF compression is a different engine.
