FAQ
Will image quality be preserved?
Quality is optimized automatically, and you can manually adjust quality and dimensions for better results.
Can I batch resize images to 150KB?
Yes for Pro accounts. Batch mode supports up to 10 files at once.
Common situations for this workflow
Online application forms and government portals that cap each image at 150KB.
Document or certificate uploads where 150KB keeps text and stamps legible after compression.
Profile or ID photo uploads that need clarity without dropping to a tiny 50KB-style limit.
Checklist before you upload
Start with JPEG - it reaches a 150KB target more reliably than PNG for photographs.
Reduce dimensions first if a detailed or text-heavy scan will not compress to 150KB cleanly.
Confirm both the 150KB size and any required width and height before you upload.
Tips to hit the target faster
150KB is a comfortable mid-range cap, so headshots and scanned documents usually stay sharp.
If the portal also lists pixel dimensions, set them too - many 150KB rejections are actually dimension mismatches.
Target slightly under 150KB so a strict upload check still accepts the file on the first try.
