Compress PDF - FAQs

How to compress PDF without losing quality

Compressing a PDF without losing quality means that you have to reduce the file size while maintaining the PDF quality, which is very challenging in practice. Here are some methods you can try:

Use a PDF compressor with control over compression settings: It should allow you to fine-tune the compression settings to balance between file size and quality.

Convert to a different PDF format: Some PDF formats inherently support better compression without losing quality. For example, the PDF/A format is designed for long-term archiving and might result in smaller file sizes.

Manually compress image in PDF: If your PDF contains images, consider manually compress the images before adding them to your PDF. This can significantly reduce file size while maintaining acceptable quality.

Delete unnecessary content: Review your PDF and remove any unnecessary pages, images, or elements. This will reduce the file size without affecting the quality of the remaining content.

How to compress PDF file size for email for free

Most email service providers have a maximum attachment size limit of up to 25MB. For example, the maximum email attachment size limit for Gmail is typically 25 MB, while the maximum file size on Outlook is only 20 MB. If your PDF file is larger than 25MB, you can follow the methods to below to compress the PDF file size for email.

Use a compression software before attaching: You can use compression software like WinZip (Windows) or StuffIt (Mac) to create a compressed archive (ZIP or RAR) of the files you want to send. This can significantly reduce the file size.

Use online compression tools: As mentioned earlier, you can use online tools to compress your files before attaching them to an email. Websites like HiPDF or ILovePDF can help reduce the size of PDF files.

Use cloud storage services: Instead of attaching large files directly to your emails, you can upload the files to a cloud storage service like Google Drive, Dropbox, or OneDrive. After uploading, you can share a link to the file in your email. This allows you to send large files without worrying about attachment size limits.
