How to Compress a PDF to 100KB, 200KB or Any Size (Free)
Job portals, college forms and email services often reject PDFs over 100KB, 200KB or 2MB. Here is how to shrink a PDF quickly without installing software.
Why PDFs get so large
Most oversized PDFs contain scanned pages, high-resolution photos, or embedded fonts. Scans are the biggest cause: a single phone-scanned page can be several megabytes.
How to compress a PDF, step by step
- Open the PDF Suite and choose the Compressor tab.
- Select or drag in your PDF.
- Pick a target size such as 100KB or 200KB, or set a custom size.
- Click compress and wait a few seconds.
- Download the smaller file and check that the text is still readable.
Tips for keeping quality
- Start with a moderate target. Squeezing a 5MB scan to 50KB will blur text.
- If the result is too soft, try a slightly larger target.
- Keep your original file as a backup.
Is it safe?
Compression runs inside your browser, so your document is not sent to a server. That matters for ID proofs, contracts and bank statements. Read more in our privacy policy.

Frequently asked questions
Will compressing a PDF reduce quality?
Some quality is traded for size, mainly in images. Text stays readable at reasonable targets.
Can I compress a PDF to exactly 100KB?
You can set a target size, but very large or image-heavy files may not reach very small targets without visible blur.
Do I need to create an account?
No. The tool is free and works without sign-up.
