Compress PDF Online Free
Use this free online PDF compressor to reduce PDF file size directly in your browser. Upload a document, choose automatic compression for a balanced result, or enter a target such as 100 KB, 200 KB, 500 KB, or 1 MB. The tool rebuilds your PDF as an optimized color copy and checks the real output size—without a paid compression service. Target-size results depend on the number of pages, page design, photographs, and the amount of detail in the original document, so an exact size is not always possible. When the requested size is too small, the PDF size reducer returns the closest readable result it can create. Processing stays on your device, making the tool convenient for forms, attachments, and everyday document uploads.

Compress PDF to a Specific Size
Choose a preset to compress PDF to 100 KB, compress PDF to 200 KB, compress PDF to 300 KB, compress PDF to 500 KB, or compress PDF to 1 MB. You can also enter a custom KB or MB value. The tool adjusts page resolution and image quality over several attempts, then returns the closest practical result. Exact sizes cannot be guaranteed because every PDF contains a different amount of visual information.
Why Reduce PDF File Size?
A smaller PDF is easier to use with online application forms, email attachments, government portals, college admission forms, job applications, and document upload limits. Reducing PDF size also saves storage space and can make sharing faster on slower mobile connections.
Is My PDF Safe?
Your file is processed locally by browser code and is not intentionally sent to Moneygita or an external compression API. The PDF libraries load from a public CDN, but the document itself stays in your browser. For highly sensitive material, you should always follow your organization’s document-handling rules.
Frequently Asked Questions
How can I compress a PDF online?
Choose a PDF, select Auto Compress or Target Size, start compression, and download the newly created PDF when processing finishes.
Can I compress a PDF to 200 KB?
Yes. Select the 200 KB preset. The tool will attempt several quality and resolution levels and return the closest readable result.
Can I compress a PDF to 100 KB?
Yes, but 100 KB may be unrealistic for a long or highly detailed document. If the exact target is unsafe, the tool returns the best result reached at its minimum recommended quality.
Will PDF compression reduce quality?
Some visual quality is traded for a smaller file. Auto mode aims for a balanced result, while very small targets require stronger compression.
Is this PDF compressor free?
Yes. The browser tool uses open-source PDF libraries and does not require a paid compression API.
Is my PDF uploaded to a server?
No. Compression is performed locally in your browser. The document is not intentionally uploaded to Moneygita or an external PDF service.
Why can’t some PDFs reach the exact target size?
Each page needs enough pixels and image data to remain readable. Page count, photographs, diagrams, and small text can make extremely low targets impractical.
Can I use this tool on mobile?
Yes. It works in modern mobile browsers, although large or long PDFs may need more memory than some phones can provide.
