Compress PDF to 1MB online, free
Compress PDF to 1MB online for free. Upload your PDF, and our compressor automatically reduces it to 1MB or less while keeping it as sharp as possible — no signup, no software, and no watermark. It's exactly what you need when an upload portal, email attachment limit, or application form caps your PDF at a specific size.
Rather than trial-and-error with quality presets, enter 1MB as your target and we progressively optimize the embedded images until your PDF fits under the limit — while keeping the text crisp and selectable. Your file is encrypted in transit and deleted automatically after processing.

Compress PDF to 1MB — FAQ
How do I compress a PDF to 1MB?+
Upload your PDF above, make sure the target is set to 1MB, and click compress. We reduce the file to 1MB or less and give you the result to download — completely free.
Will compressing to 1MB ruin the quality?+
Text stays sharp and selectable. To reach 1MB we mainly lower the resolution of embedded images, which is the part that takes up the most space in a PDF.
What if my PDF can't reach 1MB?+
We always return the smallest usable version we can produce. If a file simply can't be squeezed under 1MB without becoming unreadable, you'll get the closest result and a note that it's slightly over target.
Is it free and private?+
Yes. Compressing PDF to 1MB is 100% free with no signup or watermark. Files are uploaded over encrypted HTTPS and automatically deleted from our servers a short time after processing.
