About Optimize PDF
Try lossless PDF optimization without uploading your document. This tool rewrites the PDF structure and object streams. It does not downsample photos or remove pages. Some PDFs are already optimized, so a smaller download is not always possible.
How to use this tool
- Choose a PDF and select Convert.
- Wait while the browser rewrites the PDF structure.
- Download and compare the output size. FileLane retains the original when the optimized result is larger.
Common questions
Can I compress a PDF to exactly 100 KB or 200 KB?
This tool does not guarantee an exact or maximum PDF size. Image-heavy scans often need image downsampling, which this lossless tool does not perform.
Does this PDF compressor lower image quality?
It does not intentionally downsample images. That preserves their quality but also limits how much a scanned or image-heavy PDF can shrink.
This lossless tool rewrites PDF structure. It does not downsample images or promise a target size. If the output is larger, it keeps the original.
