Compressing a PDF reduces its file size, making it much easier to upload to websites, send via email (which often have attachment size limits), and save storage space on your device without deleting the document.
Will compressing a PDF affect the quality of the images inside?
It depends on the compression level. Most tools use "lossy" compression, which slightly reduces image quality to achieve a smaller file size. However, for text documents, the visual difference is often unnoticeable. Many compressors offer different quality settings (e.g., Extreme, Recommended, Less Compression) so you can balance file size with clarity.
Is it safe to use an online PDF compressor?
Generally, yes, provided you use a reputable service. Most reliable PDF compressor sites use encrypted connections (HTTPS) and automatically delete your files from their servers after a short period (usually between 1 to 24 hours) to ensure your privacy.
