About Compress PDF to 100KB
Many application forms cap ID and certificate uploads at 100 KB. A single scanned page usually fits at this size after compression.
If your file is a multi-page scan, compress only the pages the form actually requires.
Frequently asked questions
Will my PDF fit under 100KB?
Text documents and single scanned pages usually do. Large multi-page scans may not. If 100KB can't be reached, you'll see the smallest size the tool achieved.
Are my files uploaded to a server?
No. The tool runs inside your browser, so your files are read and processed on your own device and never sent anywhere.
Will compressing a PDF reduce its quality?
Keep text mode only optimizes the file structure and leaves everything intact, but savings are modest. Smaller file mode converts each page to an optimized image, which shrinks files a lot but makes text non-selectable.
Can I compress a PDF to a specific size like 100KB?
Yes. Enter a maximum such as 100 or 200 KB. The tool tries stronger settings until the file fits, or tells you the smallest size it could reach.
Why is my PDF file so large?
Usually because of scanned pages or high-resolution photos. Each scanned page is a large image, so a few pages can add up to several megabytes. Those files shrink the most.
How do I reduce PDF size without losing selectable text?
Choose Keep text selectable. It cleans up the file without redrawing pages, so text stays searchable. The saving is smaller than with Smaller file mode.
Does it work on iPhone and Android?
Yes. It runs in any current mobile browser. Very large files depend on your phone's memory, so compress long scans in parts if a phone struggles.
