Can you compress a PDF to 100 KB?
A 100 KB limit may be achievable for some PDFs, but the compressor cannot guarantee a target size.
Walkthrough
- Check whether your submission limit uses KB or KiB, and keep the original.
- Try High Quality, then Balanced or Maximum if image quality can be reduced.
- Compare actual input and output sizes. Inspect small print and scans before submitting.
Open the relevant Tooldit tool.
What to check before relying on the result
Text-bearing pages are copied and may barely shrink. Image-only pages are JPEG-rendered. Forms, signatures and document-level features may change.
Troubleshooting
If the output grows, the tool retains the original and does not download a larger replacement. Extract unnecessary pages using Split PDF or reduce image resolution in the source document; do not remove required content just to meet a byte limit.
Privacy and output checks
Tooldit file and text tools process their contents locally. Optional page analytics is separate, and SEO and contact tools use network services. Read the Privacy Policy. Keep original files and inspect the output before sharing it. Examples in this guide are instructions, not measured performance tests.
