// FAQ
Frequently asked
+Can every PDF compress to 100 KB?
Text-heavy PDFs hit 100 KB easily. Highly visual PDFs (lots of full-page images) sometimes need to drop to 200 KB to stay legible — our tool tells you when this happens.
+Is this lossless?
No. Hitting 100 KB requires lossy image downsampling. Text remains crisp. Photos may show very mild softening at 96 DPI.
