Upload a PDF and get a file under 100KB, ready for online forms that refuse anything bigger. We keep the highest quality that still fits.

Please keep this page open.
100 KB is one of the strictest limits you will meet. Many government services, exam registrations and scholarship forms only accept certificates, ID cards or mark sheets under 100 KB, while a phone scan of a single page is often 1 to 3 MB. The file has to lose more than 90% of its weight.
For the best result, upload only the pages the form asks for and scan them in grayscale at 150 dpi. A one or two-page document then fits in 100 KB and stays perfectly readable.
You choose the limit and the file comes out under it. No guessing between low, medium and high compression.
Images are compressed step by step and only as much as needed, so the text stays sharp and readable.
No account and no watermark. Files are deleted automatically after 1 hour(s).
Created by Adobe in 1993, PDF is the standard for sharing documents that must look identical on every screen and printer. It embeds fonts, images and layout in one file and supports passwords, forms and digital signatures.
Portals that receive thousands of applications limit each file to keep uploads fast on slow connections and storage costs low. 100 KB is enough for one or two clearly readable pages.
Select your PDF, keep the target at 100KB and click "Compress to 100KB". A few seconds later you can download a PDF of 100KB or less.
The images inside the PDF are compressed first. If that is not enough, the pages are turned into compact images. When even that is too big (very long documents), you get the smallest possible file and a message tells you so. Split the PDF or remove pages, then try again.
Yes. Text and vector graphics are kept as they are whenever the target can be reached by compressing the images, which is the case for most scans and photo documents.
We count 1 KB as 1000 bytes, so the file is slightly under the limit in both systems and every upload form accepts it.
Yes, completely free. There is no registration and no watermark is added to your files.
Files are uploaded over an encrypted connection and deleted automatically after 1 hour(s). After downloading you can also delete them immediately with one click.
Each file can be up to 50 MB.
