Compress JPEG to 100KB

This preset does two things at once: it targets 100 KB and it writes the result as a JPEG regardless of what you drop in. That combination matches what most photo-upload fields want. Visa and immigration portals, exam registrations, university admission forms and plenty of job boards state a 100 KB maximum and often add that the file must be .jpg or .jpeg, rejecting PNG and WebP outright. Converting and compressing in one pass saves the round trip through a separate converter.

JPEG is the right choice for this budget because it discards detail the eye is least likely to notice, which is why a photograph at 100 KB can still look natural at roughly 800 to 1000 pixels wide. Quality is reduced before dimensions are touched, so the pixel size stays intact whenever the budget allows. The trade-off is in the kind of content JPEG handles poorly: sharp text, thin lines and flat areas of colour pick up faint halos and blocking at lower quality. A photo of a document or a screenshot of a form will still be readable, but if the receiving system accepts PNG and your image is mostly text, the plain Compress Image page may serve you better. Transparent areas, if any, become solid white in the output.
