Getting a PDF under 100 KB
To compress a PDF to 100 KB, add it to Wispdf with 100 KB as the target. Wispdf tries different settings in your browser until the file is 100 KB or less, then tells you the size it reached. 100 KB is a tight limit. A 1 or 2 page text document often fits, while color scans and photos usually need extra steps.
Tips that help
- Make the PDF from the original file, such as a Word document, instead of scanning a printout.
- If you have to scan, use grayscale and a lower resolution. One clear page can fit. A stack rarely will.
- Upload only what the form asks for. Delete cover pages and blank backs before you compress.
Questions about compressing to 100 KB
What kind of PDF can realistically fit in 100 KB?
A short document made straight from a word processor, like a 1 or 2 page resume or letter, often fits in 100 KB with room to spare. A single scanned page can fit if it's in grayscale at a modest resolution. Several color scans or anything with photos usually won't, even after compression, so plan to trim or split.
Why won't my PDF compress to 100 KB?
Usually because it holds images. Every scanned page or photo is a picture, and pictures take far more space than typed text. Wispdf tells you the size it reached, so you know how far off you are. Then try removing pages, converting with Grayscale PDF, rescanning at a lower resolution, or splitting the file with Split PDF, which can split by size.
Will a 100 KB PDF still be readable?
Typed text usually stays sharp, because it takes very little space. Scans and photos are a different story. To reach 100 KB they give up detail, so small print, stamps and signatures can look soft. Open the result and zoom in before you upload. If something important is hard to read, send fewer pages instead of squeezing harder.
Is it free, and is my file uploaded?
