About compress image to 100kb
Online application forms often set an upper limit on photo and signature uploads, and state it in KB. The limit is set by each form, so check the exact number on the page you are uploading to before you compress.
At 100KB most phone portraits keep their full detail at a smaller pixel size, so this is a common limit for profile photos and document uploads where the face must stay sharp.
A PNG keeps every pixel, so it is often far larger than a JPG of the same picture. If a PNG will not get under 100KB without shrinking a lot, convert it to JPG first with the Convert Image tool.
Compress Image to 100KB: common questions
Does compressing to 100KB lose quality?
Some, since the file is smaller, but the tool picks the highest quality that fits under 100KB, and you can compare the result in the preview before you download.
Can I compress a PNG to 100KB?
Yes. A PNG ignores the quality setting, so the tool reduces its pixel size until it fits. Converting to JPG first usually keeps more detail.
