Recruitment platforms, company career pages and government job portals often cap uploads at 100 KB for each photo, signature or certificate scan. It is a limit that leaves room for a good-looking image, but phone photos and multi-megapixel scans still have to shrink by twenty or thirty times to get there.
This page is already set to 100 KB. It squeezes out the extra bytes while keeping a professional headshot sharp and the small print on a degree certificate readable. The compression happens on your own device, so the documents in your application are never shared with a third party.

Making a good impression at 100 KB
A recruiter usually sees your profile photo as a small thumbnail, so a 800–1000 px wide headshot is more than enough, and it fits in 100 KB with high quality. Use soft, even light, a neutral background, and crop from the top of the head to the shoulders before compressing.
For certificates and mark sheets, straighten and crop the scan first so only the paper is visible. A clean scan of an A4 page stays readable at 100 KB at around 1200 px wide. If the portal accepts PDF files, you can also combine several scans with JPG to PDF and compress the PDF.
Frequently asked questions
How can I reduce my photo size to 100 KB without losing quality?
Drop it on this page. The tool picks the highest quality that fits under 100 KB, and for typical headshots the difference from the original is not visible on screen.
Why is the 100 KB limit so common on job sites?
It keeps applicant databases small and pages fast, while still allowing a clear photo. Many systems also resize your photo again after upload.
Can I compress a PNG certificate to 100 KB?
Yes. The result is saved as a JPG, which is much smaller than PNG for scans and photos. Any transparent areas become white.
Will my documents be uploaded anywhere?
No. Your files are compressed by your browser and remain on your device.
