Compress a JPG to 100 KB
A 100 KB JPG is generous enough to keep a photo looking genuinely good while still slipping under common form limits. JPG is lossy, so the tool quietly lowers quality until the file matches 100 KB, with almost no visible cost.

How good a 100 KB JPG looks
100 KB carries a clean photo around 600x600 to 800x800 pixels with very little visible loss. Skin tones stay smooth and edges stay crisp, so this size suits document scans and clear ID photos. Most people cannot tell a 100 KB JPG from the original at normal viewing size.
JPG reaches 100 KB exactly because it is lossy and can shave bytes in small increments until the target is met. JPG and JPEG are the same format with different file extensions, so a .jpeg file lands on 100 KB identically.
Where a 100 KB cap fits
Government portals, bank verification, and many job applications accept JPGs up to 100 KB. It is roomy enough that a typical phone photo only needs a light squeeze to comply, which keeps the picture sharp.
If you need a tighter result or a different input format, compress to any size lets you set the number. To control the quality slider directly on a plain photo, reach for quality-based JPEG compression.
