About Compress image to 100KB
Upload forms for jobs, universities and visas often require images under 100KB. This compressor brings your JPG or PNG down to 100KB or less while keeping the original dimensions whenever possible, so documents and photos remain readable.
100KB is enough for clear scanned certificates and full-size photos, making it the most popular target for online applications.
Hits the exact size
Quality is tuned automatically until the file lands just under 100KB — no trial and error.
Best possible quality
The tool keeps the original dimensions whenever it can, and only scales down if it must.
