    How to compress a PDF to 1MB

    1. Select your PDF or drop it on the page. The target is already set to 1MB.
    2. Change the target if your form asks for a different limit, for example 150 or 300 KB.
    3. Click "Compress to 1MB". Several settings are tried and the best one under the limit is kept.
    4. Download the PDF and upload it to your form. The new size is shown next to the file name.

    1 MB is the limit of many e-filing systems, HR application forms and online tenders, and a comfortable size for email. Presentations and reports with photos often weigh 5 to 20 MB and can be brought under 1 MB in one step.

    The compressor leaves vector text and charts untouched and only re-encodes the images, so your document still looks professional.

    About the file formats

    PDF (Portable Document Format)

    Created by Adobe in 1993, PDF is the standard for sharing documents that must look identical on every screen and printer. It embeds fonts, images and layout in one file and supports passwords, forms and digital signatures.

    Frequently asked questions

    Can I compress several PDFs to 1 MB each?

    Yes. Select up to 10 PDF files. Each one is compressed separately to stay under 1 MB, and you download them together in a ZIP file.

    How do I compress a PDF to 1MB?

    Select your PDF, keep the target at 1MB and click "Compress to 1MB". A few seconds later you can download a PDF of 1MB or less.

    What if my PDF cannot get under 1MB?

    The images inside the PDF are compressed first. If that is not enough, the pages are turned into compact images. When even that is too big (very long documents), you get the smallest possible file and a message tells you so. Split the PDF or remove pages, then try again.

    Is the text still readable?

    Yes. Text and vector graphics are kept as they are whenever the target can be reached by compressing the images, which is the case for most scans and photo documents.

    Does 1 KB mean 1000 or 1024 bytes here?

    We count 1 KB as 1000 bytes, so the file is slightly under the limit in both systems and every upload form accepts it.

    Is MajorPDF free to use?

    Yes, completely free. There is no registration and no watermark is added to your files.

    Are my files safe?

    Files are uploaded over an encrypted connection and deleted automatically after 1 hour(s). After downloading you can also delete them immediately with one click.

    What is the maximum file size?

    Each file can be up to 50 MB.
