Frequently Asked Questions
How do I reduce PDF size for email attachments?
Upload your PDF to BA Convert, select High or Maximum compression level and optionally set a size target like Under 2MB or Under 5MB. Click Compress PDF and download the smaller file. Most PDFs can be reduced by 40-90% depending on content.
How do I compress PDF to under 1MB or 2MB?
Use our Target File Size option and select Under 1MB or Under 2MB. BA Convert will apply the necessary compression to hit your target. Note that PDFs with many high resolution images compress best while text-heavy PDFs may have limits.
What is the difference between compression levels?
Low compression preserves the best quality with minimal size reduction. Medium is balanced. High gives good compression with decent quality. Maximum gives the smallest file size but lower visual quality. For email use High or Maximum.
Why does the compressed PDF have non-selectable text?
Our compression method converts PDF pages to images which significantly reduces file size. This means the text in the output PDF is part of the image and cannot be selected or searched. This is clearly mentioned in our disclaimer before you compress.
How much can I compress a PDF?
Compression results vary by content. PDFs with high resolution images can be compressed by 70-90%. Text-heavy PDFs typically compress by 20-40%. PDFs that are already optimized may compress very little.
Is the PDF compressor free and secure?
Yes completely free with no signup required. All compression happens in your browser. Your PDF files are never uploaded to any server making it 100% private and secure.
