About this tool
100 KB suits profile pictures, online forms that ask for a clearer photo, and images you want to email without attachments piling up.
A typical phone photo at 100 KB keeps around 800–1000 pixels on its longest side and looks sharp on a phone screen.
Choose WebP if the site accepts it. It looks noticeably better than JPG at the same 100 KB.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser, on your own device. Your files are never sent anywhere, and the tool keeps working even if you go offline after the page has loaded.
Will the file be exactly 100 KB?
It will be just under 100 KB. Upload forms reject files that are even 1 byte over, so the tool always stays below the limit.
Does it work with iPhone photos?
Yes. HEIC photos from an iPhone are converted and compressed in one step.
Is it free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
