Compress to 150 KB nowThe tool opens with the 150 KB target already applied | nothing is uploaded anywhere.
Text is forgiving under compression as long as you do not shrink the pixels | keep the scan at 150-300 DPI, compress to 150 KB and every character stays legible. Photos at this size look genuinely good on screen and in print.
Typical askers: marksheets, certificates, affidavits and application attachments.
Portals reject files by the byte, so guessing with quality sliders wastes hours. This preset runs a measured quality ladder (and downscales only if quality alone cannot reach the target) on your own device, then reports the achieved size before you download. Your file never leaves the browser tab.
Will the image still look acceptable at 150 KB?
It depends on the picture: tight crops and flat subjects compress beautifully, while wide busy photographs give up fine detail. The live preview lets you judge before downloading.
Is my photo uploaded anywhere?
No. Every pixel is processed by JavaScript inside your own browser tab | nothing is sent to a server, stored or logged, which matters when the file is an ID photo or signature.
Does this work on my phone?
Yes. The tool is fully responsive and touch friendly, and the whole conversion runs in the mobile browser itself | no app install.
