How to use Compress PDF to 100 KB, 200 KB or 500 KB

  1. Choose one PDF file up to 50 MB.
  2. Select the required target size such as 100 KB, 200 KB or 500 KB.
  3. Start compression and wait while several quality levels are tested.
  4. Check the final size and readability before downloading.

Why use target-size compression?

  • Choose a limit commonly required by online application portals.
  • The service searches for the closest practical balance of size and quality.
  • The result clearly reports the final file size.

Tips for the best result

  • Choose the largest limit accepted by the destination for better quality.
  • Crop unnecessary scan borders before uploading.
  • If a document remains too large, split it only when the receiving portal permits multiple files.

Privacy and security

Uploads use encrypted HTTPS transfer. Filenames are sanitized, temporary working directories use unique identifiers, and generated files are removed automatically. Never upload a document unless you have permission to process its contents.

Frequently asked questions

Is Compress PDF to 100 KB, 200 KB or 500 KB free?

Yes. You can use this tool without registration or payment.

What is the maximum file size?

Each uploaded file can be up to 50 MB.

Are uploaded files stored?

Files are held temporarily for conversion and deleted automatically after processing.

Can I use this on mobile?

Yes. The uploader and download flow work in current mobile and desktop browsers.

Will the result be exactly the selected size?

The converter aims to stay near or under the target, but exact results depend on document content and the minimum readable quality.

Which target should I choose?

Use the limit stated by the website receiving your file. Do not choose 100 KB when 500 KB is allowed, because a larger target usually preserves more detail.

Why can a scanned PDF be difficult to compress?

Scanned PDFs contain full-page images, which usually require stronger image reduction than text-based PDFs.
