How Target Size PDF Compression Works
This tool first tries safe PDF optimization to keep the document structure close to the original. If the file is still bigger than your selected target size, the tool automatically uses page rendering and image compression to get closer to the size you need. If your selected target is larger than the compressed file, the tool can also increase the PDF file size with safe padding.
Is My PDF Uploaded Online?
No. This tool is designed to work in your browser. Your selected PDF is processed locally by the browser scripts, and the tool does not need to upload the file to a server. For sensitive files, always check your browser and website environment before using any online tool.
Tips for Smaller PDF Files
- Set a realistic target size for better quality.
- Scanned documents and PDFs made from photos usually compress more.
- If the file must look very sharp, choose a slightly higher target size.
- Text-only PDFs may not shrink as much as image-heavy PDFs.
- Set a bigger target if you need to increase PDF file size for a specific upload requirement.
- If a PDF is already optimized, the size may not reduce much.
