Frequently asked questions
Is this PDF compressor really free?+
Yes. There are no file limits, no daily caps, no watermarks and no sign-up. The compression runs in your own browser, so there are no server costs to pass on to you.
Are my PDF files uploaded to a server?+
No. Unlike most online PDF compressors, your files are never uploaded anywhere. Compression runs entirely inside your browser. Your documents never leave your device — you can even use the tool offline once the page has loaded.
How does PDF compression work?+
Most PDF size comes from embedded images. The tool re-samples images to a lower resolution (for example 150, 72 or 30 DPI) and re-encodes them efficiently, which typically shrinks scanned documents by 70–95% while keeping text perfectly sharp.
How do I compress a PDF to a specific size like 100KB or 200KB?+
Switch to “Target size”, choose your limit (100KB, 200KB, 500KB or 1MB) and drop your file. The tool automatically tries multiple quality levels and keeps the highest quality that fits under your limit.
Will compression reduce the quality of my PDF?+
Text and vector graphics stay sharp at any setting — only embedded images are downsampled. “High quality” (150 DPI) is fine for printing, “Balanced” (72 DPI) is ideal for screens and email, and “Extreme” (30 DPI) produces the smallest possible file.
Is it safe to compress confidential documents here?+
Yes. Because processing is 100% local, this tool is suitable for contracts, medical records, IDs and other sensitive documents that you should never upload to an unknown server.
