Need to shrink a PDF file down to less than 1 MB for online submission? Let Smallpdf help you!

2020 was a year of shifting habits, and one trend we spotted was the increasing need for online file submission. And a common predicament is, well, the maximum file size limitation that many online platforms have imposed.

But worry not, with our Compress PDF tool—you can quickly compress your PDF documents to 1 MB, or even less! The choice is yours.

How To Compress a PDF To 1mb or Less or Free

  1. Visit our online tool for PDF file compression.

  2. Upload your PDF file to the tool.

  3. Choose the appropriate compression level.

  4. Download your new PDF file, or try again until you’re content.


How to quickly reduce the size of PDFs to as little as 1 MB (or even KB!).

Using the best technology in the market, we will reduce your PDF documents’ size while maintaining the highest file quality. Be warned: the more substantial the compression level, the more distortion will occur in the document, especially files containing many images.

Compress Non-PDF Files As well


The good news doesn’t stop there! Our online PDF compression tool can also reduce the file size of other file types, namely JPG, Word, PPT, and Excel. Once you upload one of these files, we will first carry out the PDF conversion from that native file type to PDF format. Then, the PDF compressor will shrink the file down, as described.

In such cases, if you wish to have the file in its original format, head over to the PDF Converter, drag and drop the file in, and we’ll take care of the rest. By doing so—you can compress almost any type of standard digital document for your liking.

Secure and Free PDF Compressing


From the moment you upload your file to when you download your compressed PDF, we’ll make sure that it goes through the utmost secure processing environment. On top of that, our servers automatically delete uploaded files after an hour of processing.

Once you reduce a PDF file size, the tool will display a few available options for you to utilize before downloading your document. For instance, many people compress PDFs to 1 MB or less for emailing or online submissions. But to protect your file even further, you can proceed to encrypt your compressed PDFs with a password with our ‘Protect PDF’ tool—available via the result page.

Compress PDF to 1MB Offline


Some prefer to upload and compress PDFs to tiny sizes without the need for manual software installation—which our online tool suite fulfills. But for those who prefer traditional PDF software to manage files locally, you can check out the Smallpdf Desktop app, which allows offline conversion, modification, and of course, compression. Give it a try today!
