Frequently Asked Questions
How does it get the PDF under 100KB?
It tries progressively stronger image compression and keeps the mildest setting whose result fits, so no more quality is given up than the limit demands.
What if my PDF cannot be reduced to 100KB?
You are told plainly, and given the smallest version that could be produced. A document that is mostly text or vector graphics has little left to compress — splitting it into parts is the reliable fix.
Will a scanned document still be readable at 100KB?
A one or two page scan usually is. A longer scan squeezed to 100KB will look soft — check the page preview before you submit it.
Will the text become blurry?
No. Text stays as real text and is never turned into a picture. Only the images inside the PDF — photos and scanned pages — are recompressed.
Can I use a different size limit?
Yes — change the number or the unit, or pick one of the presets (100 KB, 200 KB, 500 KB, 1 MB, 2 MB).
Is my PDF uploaded anywhere?
No. The compression runs inside your browser, so certificates, ID documents and statements stay on your device.
