Smart PDF Compressor
Reduce a PDF’s size in the browser.
Frequently asked questions
How does this Smart PDF Compressor work?
Upload one PDF, choose a compression goal, optionally add a target size, and click Compress PDF. The result step shows the optimized size, savings, and download option when a smaller output is available.
Can I compress a PDF to a target size?
Yes. Add a target in megabytes during the review step. The tool validates that target and compares the final output against it after compression.
Why did my PDF not shrink much?
Some PDFs are already optimized or are made of image-heavy pages with limited room for further browser-side reduction. In those cases, the result step tells you that clearly instead of pretending the reduction was meaningful.
Will this add a watermark?
No. The compressed PDF download does not add a watermark.
