What is ExamFo's JPEG to KB Compressor?

JPEG (JPG) is the format almost every exam portal accepts, and it compresses far smaller than PNG for the same photo. ExamFo lets you compress JPEG to KB by taking any JPG, JPEG or even a PNG and bringing it down to any figure you type, right in your browser with nothing uploaded. Because JPEG is a lossy format, you control the exact trade-off between size and clarity with a live preview, whether you need to compress JPG to 20KB or reduce JPEG file size to an odd target like 35KB or 70KB that presets never offer.

A JPG image compressor to compress jpg image to 20kb, 30kb, 50kb, 100kb or 500kb online, and reduce jpg file size fast.

Common Problems While Uploading JPEG Photos to Exam Forms

  • A PNG signature is heavy, and saving it as JPEG cuts the size dramatically.
  • Your form needs an odd target like 35KB or 70KB that fixed presets do not offer.
  • The same JPEG looks fine on screen, yet the portal still reports it as too large.
  • Re-saving a JPEG many times stacks up compression artefacts and dulls the image.
  • A camera JPEG carries EXIF and extra data that quietly inflate the file.
  • Your photo is currently in HEIC or WebP, but the form only accepts JPG.
